Does anybody knows what is drag coefficient of a hang glider pilot with and without aerodynamical bag...?

Question

im interested what is drag coefficient of a human body in air stream. im working on a home made flying machine and this information is very important to me. thanks

Answer 1

Contact the EAA (experimental aircraft association) in Oshkosh, Wisconsin, USA

Answer 2

My hang glider (Moyes, from Australia) has a 10:1 glide ratio  with my harness which isn't aerodynamic in shape. It's all straps and arms and feet, lots of drag. Total weight is about 250lb so there's 25lb of drag at 25knots due to glider plus harness.

The same glider with an aero harness gets about 13:1 so there's 19.2 lb of drag. 5.8 lb less. The drag coefficient of the aero harness is really low, like a tear-drop so the coeff of drag is probably less than 0.2 or so.

i would guess the coeff of drag of my harness is 6lb/4sqft/(1/2rho*37f/s^2) = .93 so about 1.00.
