Is a pusher prop more efficient?
The pusher design is more efficient, because the suction forward of the prop reduces flow separation, and the accelerated flow behind it is not streaming around the fuselage (or wing), where it would create additional friction drag.
What is the world’s largest pusher configured aircraft?
Convair B-36 “Peacemaker
The largest pusher aircraft to fly was the Convair B-36 “Peacemaker” of 1946, which was also the largest bomber ever operated by the United States. It had six 3,800 hp (2,800 kW) Pratt & Whitney Wasp Major radial engines mounted in the wing, each driving a pusher propeller located behind the trailing edge of the wing.
What is the difference between a pusher and a tractor airplane?
Normally, there are two main types of propeller position; where the propeller is mounted at the wing leading edge and is known as a “tractor” and where the propeller is mounted at the wing tailing edge, which is known as a “pusher.” The wing aerodynamic characteristics of each are different and their force and moment …
Why did the b36 have pusher props?
But why use pusher propellers on the B-36? Much like the propellers on a boat churn up the water, aircraft propellers leave turbulent air in their wakes. This turbulent air passing over wing surfaces both decreases lift and increases drag. Thus, more thrust is required.
How much is an ultra light kit?
They currently have the Mini-MAX and Hi-MAX aircraft in production. This is probably one of the cheapest ultralight aircraft with a price of only $2850 USD for short kit. So if you are looking for a cheap ultralight aircraft kit the Airbike might be the plane for you!
How much does it cost to land at an airport?
Landing fees vary by airport and usually depend on the size and weight of the aircraft. Expect fees to be in the $100 to $500 range. Sometimes these fees are waived if your aircraft is refueling at the airport. The fees are used to maintain runways and airport buildings.
How many hours does it take to build a kit plane?
Kit aircraft can be built in as little as 500 hours to as many as 1,500 hours. A lot depends on the complexity of the aircraft design. Obviously, an aircraft with a retractable landing gear or a pressurized aircraft will take much more time than most of your basic metal kits.
