What's the advantage of the F4U Corsair's gull wing design?
2015年9月17日 · The wing shape in the F4U Corsair is called the inverted gull wing. The main reasons for use of this is the large propeller used in the aircraft. The Corsair design was in response to the US Navy RFP (Request for Proposal) in 1938, which mandated the following things: It should have maximum attainable speed; The stall speed should be 70 mph
How fast were propeller planes during landing on aircraft carriers ...
2017年3月9日 · The F4U Corsair had similar performance. Stall speed: Landing condition - power on - MPH 74.5 . The carrier will typically try to recover with about 25-30 knots of wind down the deck, which (by turning into the wind) will be a combination of the speed of the wind that day and the ship's speed. (We nautical types use knots, not MPH).
aviation history - Did Japan actually use any production aircraft …
2020年8月17日 · I then realized that the inverted-gull wings aircraft that I was thinking of was an American fighter, the somewhat similarly-shaped Vought F4U Corsair: This got me curious on whether any production aircraft used by the IJN (or any branch of the Japanese military) during WW2 used inverted gull wings.
Did WW2-era aircraft have constant-speed or variable-pitch props?
I want to know if WW2-era aircraft typically had variable-pitch or constant-speed propellers. Variable-pitch lets the pilot adjust the propeller blade pitch. "Constant speed" is the same as variable-pitch, but the engine does it automatically to keep the best performance at …
What is this wire going from mid-fuselage to the tail on this 737?
2017年4月13日 · It is an HF (High Frequency) antenna. It is used for aircraft to communicate on overseas flights. VHF (Very High Frequency) airband radios are used for normal local and cross country flights.
What are the pro/cons of polyhedral cranked wings?
2016年2月24日 · When this happens, the AOA on all main wing panels and tail plane is reduced since the airplane has an upward velocity component in the slipstream, resulting from this upward translation (without rotation in pitch). The result is that the entire wingspan and all the wing panels of the polyhedral have less difference between them in AOA.
How is fuel drawn from drop tanks in WW2 airplanes?
Earlier patents (image shown) that correspond with WW2, as far as I've seen, don't mention any relevant internal structures. And two Wikipedia articles weren't helpful: Aircraft fuel system; Drop tank; Most I could find was an F-86 manual on Google Books. And it mentions the jet engine providing compressed air into the tank to draw fuel (the ...
Why were the fronts of the Messerschmitt Me-109 painted yellow?
2018年1月8日 · After seeing the movie Dunkirk I learnt that the Luftwaffe didn't actually use the yellow coloring on the Me-109 until a few months after the battle of Dunkirk.
What are the advantages of more than 4 propeller blades?
2015年11月19日 · This increased structural weight is unacceptable as leads to a vicious cycle. An extreme case of this is the F4U Corsair, which had an inverted gull wing to accommodate the huge three bladed propeller required for the extremely powerful engine. Increase the rpm The problem is again the tip speed, which can increase drag significantly at high ...
Why do most single propellers have a clockwise rotation?
The engine and propeller are a gyroscope and have a great gyroscopic effect on a light airplane like the Sopwith Camel. Gyroscopic procession for a clockwise rotating engine and propeller meant that right tuns tended to force the airplane down into the ground (bad) but left turns tended to force the airplane up (good as long as you don't stall).
