Pressure Suit, Lower Torso and Legs, RX-2 and RX-2A

This is the lower portion of a Litton Corporations constant volume suit, the Litton RX-2 or RX-2A. Litton began adapting its line of vacuum chambers suits first for the Air Force in 1955 and then for NASA in 1964. The Litton suits were articulated exoskeletons that maintained a constant volume through a full range of motion. Litton delivered the RX-2 suit to NASA Manned Spacecraft Center in December 1964 as a solution to the problems of bending at the hips in previous models. The RX-2 and RX-2A models differed in the weight and design of the upper body, thus the lower sections were interchangeable. This was the first of the constant volume suits to have all-metal rolling convolute. This suit is constructed predominantly of aluminum, and has electrical connectors and fittings. Due to bulk considerations, the constant volume suits were never used as mission equipment.

NASA transferred this portion of the RX-2 to the museum in 1971.
