The present investigation and test series involving the M101 34-ton cargo trailer has consisted of five drops of the vehicle at impact velocities ranging from 25.4 fps, for the initial drop, to 55 fps for the fifth and final drop of the series. During the series, the design impact acceleration was varied from 20-30g. The cushioning system used for each drop of the series is described and the damage sustained by the vehicle during that drop is discussed. It is concluded that this vehicle can be dropped at impact velocities up to 50 fps without any damage, if a properly designed cushioning system is employed to dissipate the energy of the drop. Recommendations for improvements, from the airdrop standpoint, in the design of the vehicle, are included.
