X-38 Program Objectives and Requirements

Phase 2-A full scale, approximate X-24A shape without outboard fins and low-cost mockups. These will include parachute controls but no active vehicle control systems or aerodynamic surfaces (inert). These vehicles will be dropped from a C-130 at the Army test facility at Yuma, Arizona.

  1. Demonstrate deployment, autonomous flight, and landing flare capability of a parafoil/payload system with a wing loading of 2.0 pounds per square foot.

  2. Make a preliminary evaluation of the touchdown dynamics of the full-scale vehicle/parachute combination.

  3. Measure stability and control of the full-scale vehicle/parachute combination.

  4. Demonstrate integration and operation (including guidance) of the Guided Precision Aerial Delivery System (GPADS) parachute recovery system. This system has been developed by Pioneer Corporation under contract to the US. Army for use in the delivery of military equipment to specific target areas.

  5. Begin assessment of parachute system reliability.

  6. Measure parafoil riser and ground impact loads for structural analysis.

  7. Demonstrate composite structure integrity.
