Book Description
An analytical study was conducted to develop a procedure for determining the deceleration characteristics of vehicles landing on gas-filled bags of various arbitrary shapes. The analysis developed is applicable for landing on planetary or lunar surfaces for sinking speeds that are small compared to the sonic velocity of the gas contained within the bag. For relatively high velocities a light gas such as hydrogen or helium should probably be used. A series of calculations was made for four bag shapes for impact on the earth at seal-level conditions for sinking speeds consistent with descent by parachute to determine how deceleration characteristics were influenced by various factors entering the equations.
