Electrically Powered Ultralight Aircraft

The power required to overcome drag is 1/2(p*v^3*A*C) No. It is v^2 unless they have changed the physics since I was an aero engineering student back in the 70s. Yes. The drag goes up with the square of velocity, the POWER required to overcome the drag goes up as the cube. Force: Fd = 1/2(p*v^2*A*C) Power: Pd = Fd * v = 1/2(p*v^3*A*C) -- Jim Pennino Remove .spam.sux to reply. |
