Make a plane powered by battery 10 engines and can start the helicopter and as effective as a plane. This is a concept the researchers developed the NASA shell called the lightning or GL-10.high technal news
The team, the NASA Langley RESEARCH CENTER, Hampton, Virginia, the idea initially analyzed as a potential factor of the vehicle without air transport pilots (UAV). "We have some options, this approach could well for ", said Bill Fredericks, an engineer in Aerospatiale. "It could be used the small delivery of packages or vertical takeoff and landing, long endurance surveillance for agriculture, mapping and other applications. A revised version at the level -- is far more important that what we are now one -- both of four persons was personal air vehicle size." The
GL-10 is currently in the phase of the planning and testing. The original idea was the development of a range of 20 feet (6.1 m) aircraft powered by Dieselmotoren-Hybriden electrical, but the team began with the smaller versions for the examination, builds the prototypes quickly.
"We have built 12 prototypes, starting with simple five pounds (2.3 kilograms) models of foam then 25 pounds (11.3 kg), heavily modified the fiber Hobby kits aircraft way of all to 55 pounds (24.9 kg), high-quality carbon fiber, GL-10 builds in our model shop by experienced technicians, " said the engineer aerospace David Nord.
"Each type we contributed to the costs at the lowest answer technical now. We are missing some of the first prototypes of 'landings hard" as we learned of pilotage services configure the system. But we discovered something any loss and could continue to make progress."
Recently, on a day in the spring, the engineers, the GL-10 testing their wings to a military base about two hours road Langley Research Center of NASA. The aircraft he has a size of 10 pieces 3.05 m), eight electric motors, the fender, two electric motors on the tail and weighs more than 62 pounds (28.1 kg) Start.
Hover tests already exceeded -- but also how helicopters -- with even colors. But now that there was a large obstacle -- the transition from the vertical before " Flugel-Kosten " Vol. How the engineers have designed, full scale vertical takeoff and landing "tilt rotor" such as the V-22 Osprey will give you -- is not simply because of the difficult aerodynamics in Vol.
"during the flight tests, we enforce the stationary flight, the wing-instructs vol than a plane again then conventional return steady flight. So far we have five flights," said Fredericks. " We were pleased. We are now working on our second objective -- to prove that this concept four times more efficiency aerodynamics in vol cruise a helicopter "
as John's the GL-10's pilots main. He says his engine had its flag ten high and low, but in reality not stolen more than one schema with three engines from the point of view of the control.
" The four engines on the left-hand page is the same control," said Johns. " The four engines also work together on the right-hand wing. Then the two on the same order received tail." A further advantage
for the GL-10 in addition to its versatile vertical takeoff and landing capacity on noise or missing him. " This is quite calm," said Fredericks. " The prototype is more muffler a neighbor with a lawnmower right engine with gasoline. " The next step
in the GL-10 Test Program try a confirmation of your effectiveness aerodynamics, but first, a judgment of the Association for vehicles I Systems International 2015 conference in Atlanta may 4-7. The GL-10 is the heart of a exposure at the center of policy making some Langley RESEARCH CENTER NASA The VAT research.
