The HL-20 lifting body was developed as a low cost solution for getting to and from low Earth orbit. HL-20 lifting body was designed to have a powered deorbiting accomplished with an onboard propulsion system while its reentry was to be nose-first, horizontal and unpowered. Designed to carry up to ten people and very little cargo, the HL-20 lifting body was to be placed in orbit either launched vertically via booster rockets or transported in the payload bay of the Space Shuttle orbiter.

The HL-20, also known as personnel launch system (PLS), is a lifting body re-entry vehicle that was designed to complement the Space Shuttle orbiter. This example requires Control System Toolbox™. In this block, you can choose a previously saved data file, a Signal Editor block, or a set of constant values. If the FlightGear interface is unavailable, you can simulate the model by closing the loop using the alternative data sources provided in the Variant block. Visualization for this model is done via an interface to FlightGear, an open source flight simulator package. If Parallel Computing Toolbox™ is not installed, the analysis is run in serial. If Parallel Computing Toolbox™ is installed, the analysis is run in parallel.

To analyze the effects of actuator failures and wind gust variation on the stability of the vehicle, use the 'Run Failure Analysis in Parallel' project shortcut. The entire model simulates approach and landing flight phases using an auto-landing controller. It also includes effects of the environment, such as wind profiles for the landing phase. The vehicle model includes the aerodynamics, control logic, fault management systems (FDIR), and engine controls (FADEC).
