December 16, 2022, 15:49	Drag and Moment Coefficient	#1
ErenKartal0 New Member Eren Join Date: Dec 2022 Posts: 1 Rep Power: 0	Hi, I am working on a rocket. To determine the drag and moment coefficient. When calculating the drag force, I need to set an area value as a reference value. should I choose the cross-sectional area or the surface area of the nose cone as the reference value? When I selected the surface area, the drag coefficient was very low (like 0.04 in a 250 cm rocket). Is this normal? Another question is, How can I determine moment coefficient of the rocket? Please Help me!!!
