The HL-20, also known as personnel launch system (PLS), is a lifting body re-entry vehicle designed to complement the Space Shuttle orbiter. Designed to carry up to ten people and very little cargo[1], the HL-20 lifting body was to be placed in orbit either launched vertically via boos...
Also known as the ACRV (Assured Crew Return Vehicle) or PLS (Personnel Launch System). the HL-20 was a lifting body re-entry vehicle based on the Russian BOR-4 design. It was designed for two flight crew, eight passengers, and piloted landing at airfield on landing gear. The HL-20 w...
The HL-20, also known as the Personnel Launch System (PLS), is a lifting body reentry vehicle designed to complement the Space Shuttle orbiter. It was developed originally as a low-cost solution for getting to and from low Earth orbit. It can carry up to 10 people and a limited cargo...
The human factors testing of the HL-20 personnel launch system full-scale model was conducted in both the vertical and horizontal positions at NASA Langley Research Center. Three main areas of testing were considered: an anthropometric fit evaluation, the ingress and egress of a 10-person crew,...
