does a propeller screw itself on air or is it just reaction

[jf1981]

See what happens in static (standstill on the ground), imagine that the same continues to happen when building up speed except that the slip will reduce i.e. the speed transfered into the air locally will diminish.


Basically the air is pulled backward therefore speed of aircraft 500 km/h => propeller pushing air at speed >500 km/h e.g. 550 km/h.

In other words, the propeller is a real airscrew, it works with a slip, it works as a wing, it can be stalled but works well when it generates lift (thrust) without being stalled.

you are just being plane rude imo raids has a curious mind and those have been the most well remembered after time because you dont find new things by following others ideas but making owns. For Riad my advise is not give up but develop your skill it takes time and meanwhile you can maybe have dayjob and save money for future when you make breakthrought and need financing

No...because the spelling is identical and it would fit perfectly into the Narcissism you suffer from, youre obsession with madness would be just the thing to inspire you to create a profile using House as an avatar, also pointing out the fact you are really the troll I have claimed you were.

forgive me if my spelling is not correct always but we are not all english speakers by birth. you make very curious remark about house i believe you are a fan? You can claim we are same person but i does not make it true also ive read these boards for long and it has been you more like troll who always attacks some people and creates argument. if you don't like someone you can ignore imo. but i have nothing personally against you
