The Air-Cell Suspension System - A Solution to Off-Road Mobility Problems 690152

Recent studies by Missiles and Space Division-Michigan, LTV Aerospace Corp., have quantitatively verified that the air cell track/suspension concept originally applied to the pneumatic all-terrain amphibian (PATA) vehicle offers a unique solution to off-road mobility problems of tactical vehicles. Analog computer simulation techniques were employed to determine ride characteristics and experiments with scaled models were conducted to analyze air cell performance in water and soft soils. This paper covers current efforts to develop and perfect the air cell concept, concentrating on analytical studies and recent significant design improvements that promise improved suspension capabilities.
