While impulse forces not acting on the centroid, the influence of accessional attack Angleoscillation amplitude, impulse force scale and function time interval on range correction was discussed.
In order to study dynamic stall phenomena of an aircraft in portrait at a high Angleof attack, designing a measuring device of heave oscillation for a low speed wind tunnel.
