>flying planes backwards >what are UAVs Pusher-configuration planes have been used may times throughout history. They've never really been that popular though. Keep in mind, jet planes are pushers as well.
>>12504014 The advantages? Forward visibility is increased, the change in configuration allows for a shorter fuselage, the flight is supposedly a bit more stable, and... there's not a whole lot else I'm seeing that's significant.
Mostly, it seems like the big advantage is that it allows planes like UAVs to mount more avionics and surveillance equipment in the front without needing to worry about obstruction by the propeller (and the rest of the engine).
Incidentally, this is one of the most uncited wiki articles I've ever seen, but I'm too lazy to check why.
Pushers were popular around the beginning of flight, and then went out of style in favor of other configurations. It occasionally shows up in weird modern designs or ultralights, but possible the most well-known use of the pusher configuration is in modern UAVs.
>>12504014 There are quite a few advantages, a least in terms of stability and aerodynamics. The stabilizers can afford to be smaller since the engine tends to self-stabilize, and thus saves weight, and at the same time there is basically no drag due to propwash. Wikipedia has more to say on the topic and is probably a more credible source than me, however.
>>12505833 Cooling when the plane is stationary is probably the biggest reason. Pushers tend to overheat. Ruggedness is another factor. Tractor prop + taildragger minimizes prop strikes, especially on undeveloped or impromptu runways.
>>12505833 Tractor configuration was popular for airplane for several reason : - firstly the large size of propeller was critical - then it greatly simplified landing and taking of at a time where the plane were not very stable - lastly it allowed to cool the engine much very easily. (and the aerodynamic bellow 400km/h wasn't to hard on that)
To give an example : the Grumman F4 particular wing come from a redesign to avoid very long landing gear, themselves a result of the huge propeller fan.
Then there's also that constructor were used to that (stable) aerodynamic design. Nowadays thanks to computer we can make planes that are inherently instable and would not be flyable by human if the flight-computer didn't micro-corrected itself.
>>12506002 >we can make planes that are inherently instable and would not be flyable by human if the flight-computer didn't micro-corrected itself Pretend I'm an idiot and explain why we'd want to make an unstable plane. More maneuverable?
>>12506736 That's hard to pretend, those thing aren't obvious to anyone. Me I happen to be an aeronautics technicians.
In short increasing stability mean your aircraft will resist more attempt at turning, your ailerons aren't just to change the attitude but also to fight of the aerodynamic force pushing you back into Flow/Gravity/Thrust stable position. ex : Airliner are made to stay stable even if you don't touch the command.
If you built the plane the other way however... you have to keep it from doing thing like Cobra. http://en.wikipedia.org/wiki/Supermaneuverability
So fighter of the far future might look like a mix between Yukikaze and Macross, Turn on a dime and own the skies with thrust vectoring.
