About Orbital Re-entry Experiment (OREX)
The Orbital Re-entry Experiment (OREX) flight experiment is part of the research for the H-II Orbiting Plane (HOPE).
The OREX flight experiment is part of the research for HOPE to answer some critical technical questions. OREX is especially designed to acquire the following data related to atmospheric re-entry:
- 1. Aerodynamic and aerodynamic heating data during re-entry
- 2. Heat-resistant structural data during re-entry
- 3. Communications blackout data during re-entry
- 4. GPS navigation data during re-entry and in orbit
The OREX vehicle has a blunt-cone shape. The front of the vehicle, which is subjected to aerodynamic heating du-ring re-entry,is constructed of carbon/carbon material and ceramic tiles. These heat-resistant and thermal protective materials are planned to be used in HOPE. Temperature sensors and pressure sensors are installed in the vehicle.
