Sorry that I can't write English well.
I was wondering how can I consider a UAV thrust power for wind effects.
Assuming a wind velocity of -7 m/s, uav velocity of 10m/s and the stall speed is 10 m/s.
Considering that the desired velocity of the uav must be close to the stall speed. And, assuming that the wind is opposite to the flight direction.
With this information the uav velocity should be 3m/s? And if that's the case, how can I calculate the thrust force.
I'll add a figure and clarifying question. first, I desire minimize thrust power of UAV for flight.
Like a figure, If the wind speed is 7m/s and the UAV speed is 10 m/s, ground speed must be 3m/s.
however, I thought relative velocity for a UAV is 17m/s. And To minimize thrust, The UAV closed to the stall speed(stall speed is 10m/s). I thought the UAV need only UAV speed over than 3m/s.
And if that's the case, how can I calculate the thrust force.
