Aerodynamic Forces on an Airdrop Platform

attack over the range -10o to 178o and with the plate undergoing dynamic pitching which was scaled from full-size platform motion. The results showed that the dynamic pitching of the plate significantly increased the lift and drag coefficients of the plate when compared against the plate at static angles of attack. The peak lift coefficient was increased by 72% and the maximum drag coefficient was increased by 350%. Although the peak lift coefficient occurred at the same angle of attack in both cases, the peak drag coefficient was delayed by ~42o with the dynamically pitching plate.
