but no one desing the aircraft to be unstability it is just choise between light stability and heavy stability ( the distance between ac and cg= static margien )and the ac shoud be after the cg then u look for the range for the movment of the cg forword or backword

trying help Better than spell check i think that arent u?

yes sure hope it help u just read it well i will give u the name of it becous i don't have its link it's name is (report no.690 longtudinal stablity and control with special reference to slipstream effects)

all i know the choisen limit for static margin is from 1% to 40% and as u increas the static stabilty u decreas the contrlabilty so for good manuvers u need the a/c to be light stability

thx for the re and i fiend out report for NASA and after working in it i think the effect will be increas in the dunimec pressuer and increas in the roll moment due to propwash as the thrust increas

i will make an report about the propeller efficiency can anyone help me and tell me the things i need to put in this report and the references i can use

that for my graduate project and i need that effect to calculate tha stabilty and how the slipstream effect in it

could anyone help me in that please? i want to to detmine the effect of the propeller slipstream on the horizontal tail the aircraft is pusher and the propeller in front of the horizontal tail the distance is 15cm and the propeller diamter is 40cm or anyone help me with references
