1. The problem statement, all variables and given/known data
I need to find required thrust power for lockeed s3a. I know Thrust=Drag in horizontal flight.
For take off, need to use the take off angle, split the Weight (G) into 2 components using the takeoff angle... Same for landing.
G=19278kg ---> 19278*9.81=189,1kN
Wing area=22m(in square)
Expluatational overload = 4
2. Relevant equations
G=Y ; G=weight, Y= Lift
T=Q ; T= thrust, Q=drag
Q=0.5Cx*(air density)*S*(v in sq)
I dont have the Cx...
3. The attempt at a solution
expluatational overload = (P-Q)/G
Anyhow i was thinking, if theres a way to calculate the required thrust using airspeed?
Btw in wikipedia it shows the Thrust for that aircraft is 2*41.26kN
