This was the first time the event has been hosted in the country.Precision flying competitions test the fundamental skills of pilots flying solo in single-piston engine aircraft. Armed with just a compass and map, participants have to follow a precise flight path while sticking to a tight time limit, complete observation tasks from the air to the ground while navigating the plane, and make inch-perfect landings on short, narrow airstrips with trees and other obstacles on the approach.The sport is the aerial equivalent of orienteering.With ever-increasing automation in modern planes such skills aren’t put to the test in everyday commercial flight, meaning that those who compete in precision flying “represent the cream of the crop in terms of good, solid aviation practice”, says director of the 2011 champs Antony Russell.This year’s championships included host team South Africa, as well as participants from Norway, France, Finland, Denmark, Austria, Switzerland, Sweden, Russia, Czech Republic, Poland, New Zealand, UK and Germany.Poland was named the overall team winner, with member Michal Wieczorek being crowned the individual world champion for 2011. Czech Republic came second, France third and South Africa fourth.‘Felt proud to be South African’South Africa’s Hans Schwebel has been competing in the sport since 1994, with 2011 being the 18th time he has represented the country at the world champs. He’s a private pilot living in Brits, North West, and has his own business, which gives him the flexibility to practise as often as he can. He started preparing for this event three months ago, flying as often as three times a week.“But there’s always stiff competition from overseas – a lot of the competitors are commercial pilots who fly and get to practise every day. There are also far more precision flying competitions and events in Europe than here,” he says.Schwebel believes precision flying has made him a better pilot.“Today with all the modern GPS systems, you press a knob and it tells you exactly where to go. But when there’s a failure in the airplane, most of the pilots don’t know what to do anymore. With precision flying you do it the old way – you have a map and a compass and you follow the road,” he says.“The highlights of this year’s competition were coming second and the camaraderie from the South African team – it made me feel very patriotic. It’s a very special feeling. It’s also a way of giving back to the country. I want to encourage more youngsters from this country to join the sport – and I hope that my performance this year serves as an example to them that it is possible to excel.”The next precision flying world champs will be held in two years’ time, probably in Europe, and Schwebel says he’s going to do all he can to make the national team again.‘I love this country’One of the youngest competitors at this year’s event, 30-year-old Michal Wieczorek is a commercial pilot working for a charter airline in Poland. He’s been flying for 11 years and participated in his first international airsport event in 2003 at Sun City, also in North West.He attributes his love of flying and talent for precision flying in particular to his father, who also used to compete and excel in the discipline.“The flying conditions in South Africa are very different from those in Europe. Because it’s so hot, you have to fly at higher density altitudes, which decreases the performance of the aircraft. Navigation in South Africa is also completely different – there’s bush everywhere. The first few days of practice here were very hard for me,” he says.It was determination and cool-headed landings which clinched the 2011 title for Wieczorek.“After the second navigation stage I thought I had no chance of even coming in the top three, but the landings stage on last day of the competition changed everything. There’s a lot of pressure to make the perfect landing and if the nerves catch you, it’s over – but I felt less pressure because I didn’t expect to win. When I thought the game was over for me, I just wanted to end it off with good landings – unlike Czech Republic’s Jiri Filip, who did well in the first stages and the pressure was on for him. But I can say I fought ’til the end.”He says competing in South Africa this year was like coming home.“This is my third time in South Africa. I really enjoy being here – I love this country. South Africans are very hospitable and helpful – I’ve got many friends here and I feel at home.”Wieczorek believes one of the reasons why former Eastern bloc countries do well in precision flying is because of a familiarity with older planes and less advanced automatic navigation systems.“We don’t have that many aircraft with modern avionics. We train in old planes. Although they’re in very good condition, they don’t have GPS systems – we have to use a map and conventional navigation techniques as you have to do in precision flying.”But it’s also Poland’s coach, Andrzej Osowski, who primed the team for this year’s champs.“Andrzej gives us a hard time and trains us well. He’s being doing it for more than 25 years and is very good at what he does.”Wieczorek says his aim now is to defend his title at the next world championships and participate in the sport for as long as he can.last_img read more

A Heat-Recovery Ventilation System for the Potwine Passivhaus

first_imgWhere should the ventilation vents go?At left is an image of the exhaust vent in the kitchen. The architect and Zehnder seemed to have two different philosophies about where each vent should go. The architect intended to place exhaust vents in the kitchen and the two bathrooms, and to place supply vents in the bedrooms and the main living area. Zehnder seemed to think that supply vents weren’t needed in the main living area because the supply air from the upstairs bedrooms would filter downstairs.On one hand, the architect’s configuration seems like a better idea because the living area is a large space and it would be nice to have fresh air piped there directly. On the other hand, the bedrooms are the locations where CO2 buildup will be the greatest — small spaces, closed off all night, with people breathing inside — and therefore would benefit from as much fresh air as possible.Three weeks later, we still appear to be at an impasse. Tightly sealed homes are more comfortableWhen you seal up the exterior shell of the building, it makes for a more comfortable home in addition to saving energy. When you open the front door, cold air can’t rush in — it has nowhere to go. There are no cold drafts throughout the house because cold air isn’t leaking in anywhere.If you build your house according to the Passivhaus standard, it should take 1 hour 40 minutes for all of the air in the building to leak out and be replaced by new air when the house is depressurized to 50 Pascals with respect to the outdoors. (This is equivalent to 0.6 air changes per hour at 50 Pascals. It’s not exactly clear to me why this particular number is the target.) A typical home will leak out all of its air in 30 minutes, equivalent to leaving the front door wide open! As they set out to build a single-family Passivhaus on Potwine Lane in Amherst, Massachusetts, Alexi Arango and LeeAnn Kim asked themselves, “Is it possible to live without burning fossil fuels?” One measure of success would be meeting their goal of net-zero energy performance. This is the ninth blog in a series. Alexi Arango is an assistant professor of physics at Mount Holyoke College in South Hadley, Massachusetts, where he and his students conduct research on next-generation photovoltaic cells. Arango teaches a joint physics/environmental studies course on renewable energy. Arango’s blog is called Potwine Passive House. The amazing ventilator brings in fresh air without wasting energyA ventilation system is designed to address this problem, bringing in fresh air to every room while miraculously not wasting much energy. It’s ingenious and surprisingly simple — probably one of the coolest energy-saving ideas ever!The heart of the system is a type of heat exchanger (shown in the image above) which takes cold air from outside and pulls it through tiny pores. Each pore is surrounded by another set of pores flowing warm air from inside in the opposite direction. As the cold air passes by the warm air, almost all of the heat energy (up to 95%) transfers from the warm air to the cold air. It’s easy to think that the temperature of the two air flows might equilibrate to some intermediate temperature, but that’s not what happens. The real life Zehnder ComfoAir 200 HRVThe actual ventilator, called a heat-recovery ventilator (HRV), looks like a big rectangular box with squid-like flexible ducts going everywhere. It’s installed in the attic space and the ducts are routed down to each room. The installation seemed to be pretty quick and easy — it took two guys about two days, although we ran into an issue.center_img The secret behind how it worksImagine two tubes, side by side, shown at left. One has cold air entering from outside, one has warm air entering from inside. Since the two tubes are in contact, they will have pretty much the same temperature at each cross section along the tubes, warmer near the inside and cooler near the outside. As air passes through the tubes, heat is transferred between the tubes in order to maintain the temperature profile along the length of both tubes. Notice how incoming cold air is heated up to room temperature and outgoing warm air is cooled down to the outside temperature. The efficiency of this process can be very high as long as the temperature difference between the two tubes is small and the thermal conductivity of the tubes is high. The same process runs in reverse in the summer. You are getting sleepy and sicklyPeople need fresh air, otherwise they’ll start to feel a little dizzy and tired due to the build up of CO2 and lack of oxygen. At 600 ppm of CO2, air starts to feel stuffy. At 1000 ppm, you’ll start to feel drowsy. Even measurements of typically constructed homes find that CO2 concentrations in the bedrooms at night with the windows closed will often reach over 2000 ppm!The more tightly sealed the house, the worse the situation gets. Furthermore, toxic gases offgasing from glues, coatings, paints, and plastics will cause long-term health problems if they are allowed to build up in the home. June 5, 2014: The amazing ventilation systemBack from my trip to Korea and Japan, I have three weeks of exciting work on the house to catch you up on. The ventilation system went in, although we ran into some issues about where to put some of the vents.

Junior World Cup victory puts Indian hockey on crossroads again

first_imgGolden boys: The Indian hockey team with the Junior World Cup trophyOne night during the junior men’s hockey World Cup India captain Gagan Ajit Singh sat in his hotel room in Hobart, stuck at the bottom of the world. Hobart is a long way Down Under, but Gagan was talking,Golden boys: The Indian hockey team with the Junior World Cup trophyOne night during the junior men’s hockey World Cup India captain Gagan Ajit Singh sat in his hotel room in Hobart, stuck at the bottom of the world. Hobart is a long way Down Under, but Gagan was talking history, not geography.India had just lost a crucial pool match to Australia and Gagan asked the question Indian hockey has been asked for 20 years. How is it that every time it really counted, someone else ended up celebrating and the Indian team had to put its heads down and leave the field.”Yaar, hum field pe kab nachenge (When will we be the ones dancing on the field)?” Gagan asked roommate Arjun Halappa. “Hamara din kab aayega (When is it going to be our day)?”Surely now, with the Junior World Cup trophy held up to an astonished nation, every one in Indian hockey understands. When they plan for it, when they prepare for it, when they will it, it can be their day.For the first time in more than 25 years India returned from a world hockey event with something other than regrets. India has won only three major titles in 25 years – the 1975 senior World Cup, Olympic gold in 1980 and Asian Games gold in 1998 – far too little for a country that once painted hockey’s greatest works of art but now struggles to read its modern textbooks. The under-21 World Cup and the way it was won could prove to be the key to the difficult translation.Two days after the Indians had to swallow the defeat versus Australia, they played the mighty Dutch with only one option: victory. Coach Rajinder Singh, who spent a fitful night thinking of formations, didn’t spare his team the truth.advertisement”I told them if they couldn’t win that match, there would never be a revival of Indian hockey,” he says. That’s a very heavy cross to carry even if you’re not running full tilt at goal, hockey stick in hand, white ball in focus, eyes darting, heart pumping. But Rajinder’s words freed his side.They played like it was the final, running on a battery of self-belief and energy. The Netherlands equalised three times, but the Indians scored still one more to win 4-3. They beat Germany 3-2 in the semis and Argentina 6-1 in the final.Aussie junior team coach Colin Batch was impressed. “The Indians kept improving throughout the tournament. They attacked very quickly, but also had very good defence, launching the ball a good 50-60m out of defence, bypassing the midfield,” he told INDIA TODAY.Attack and defence are not two sides of a coin but the elements of the precious metal that makes it. Post-Hobart, there is celebration over the fact that the Indians won playing “traditional” hockey with five forwards and not the “European style”. Former Olympian and ex-coach Balkishen Singh differs.”The game that we displayed was a mix of Indian skills and European thrust. It cannot and must not be interpreted as a triumph of the so-called Indian classical hockey. India has clearly evolved a new style of hockey,” he says.It’s what is being worked on at the national camp, the seniors argue, call it what you like. The tactic Batch singled out – the scoop out from the defence – is a signature move. Rajinder explained it was taken to thwart counter-attacks, break tight man-to-man marking and open up the play.The precise, nimble hand of skill fitted into the glove of modern hockey – in some parts, they’re already calling this the “Eurasian” style. Never mind the name tags. The victory was a result of a sustained programme of training and international competition for the past three years.”The 2001 Junior World Cup was seen as a target from August 1999,” says C.R. Kumar, who coached the junior squad until earlier this year. Of the 18 players in the team, 14 have played for India at various levels: juniors, ‘A’ teams, second XIs, developmental teams as well as the seniors.Most other teams in Hobart also had players who belonged to their senior squads, including two Australian internationals who had 100 caps between them. So while the Indian experience may have helped, what may have worked more was that they had played in each other’s company very often. The team was sent to Australia two weeks before the start of the Junior World Cup for practice games and acclimatisation to Hobart’s temperatures that sometimes hit 4 degrees Celsius.advertisementEvery little bit helped. The programme now in place for Indian juniors from the under-14 levels upwards is the IHF’s one bright idea that is showing results. But its feudal management policies often threaten to undo all that good work.Continuity in personnel is seen as dangerous and mild dissent is considered armed rebellion. Kumar was suddenly moved out to the senior camp at the start of the year. Rajinder, who had previously worked with the under-18s, was announced new coach two months before the World Cup.Fortunately the team made the most of Rajinder’s expertise and ensured that Kumar’s work was not wasted. Now, when there should be talk of how to translate the win into success at the senior level, there are calls to sack the seniors and groom the glory boys from Hobart for the 2004 Olympics.Senior coach Cedric D’Souza ignores it all. “The victory will give these boys confidence – when they come into the national camp they will push the seniors, there will be two-three guys fighting for one spot. It’s a healthy competitive atmosphere and that’s fantastic,” he says.The senior World Cup – the true barometer for India’s standing in the world game – is only four months away and every step taken from here on is critical. In 1997, India had finished runners-up in the Junior World Cup.The desire to fast-track those players into the senior team led to upheaval, heartburn and no less than four changes of coaches between 1998 and 2001. Former Olympian and selector M.M. Somaya wants perspective to prevail and the younger players to develop their own analytical skills.The juniors are scattered and savouring victory. Gagan to Ferozepur where there are two hockey Olympians in his family: father Ajit and uncle Harmeek.Player of the tournament Deepak Thakur to Una to talk to his father, a driver with the Himachal Pradesh Government, about how he scored 10 goals. Deep defender Jugraj Singh, whose penalty-corner hitting is called world class, to Rayya near Amritsar for an overdue haircut.And Halappa to Coorg where his parents want to know why his brand-new Oakleys sunglasses, the cool sportsman’s most vital accessory, cost more than a washing machine.To a man they are energised and empowered. What happened to very few Indian hockey players in two decades happened to them. Their day arrived. They danced. Someone else left quietly.Which is why Hobart is more than an achievement or a landmark for the sport. Hobart is hope itself. The men who run Indian hockey must now decide whether to let that hope float or sink.- with Rohit Brijnath and bureau reportslast_img read more

Mumbai Test: Ravichandran Ashwin dents England after Keaton Jennings debut hundred
