PRIMARY ADVANTAGE
Zero Parasite Landing Gear Mass
VALIDATION
Runway Prototype & Flight Trials
§ 1.0
The Engineering Problem
Conventional retractable landing gear adds 4% to 8% dead weight to an aircraft, consumes critical internal fuel volume, and introduces wheel-well thermal sealing vulnerabilities on supersonic and hypersonic airframes.
§ 2.0
Patented RLG Architecture
Invented, engineered, and patented an autonomous ground-assist Remote Landing Gear (RLG) system at Destinus. The RLG acts as a mobile ground cradle that carries the aircraft during takeoff roll and synchronizes beneath the airframe for runway recovery—completely decoupling landing gear loads from the flight vehicle.
§ 3.0
Key Engineering Capabilities
- Eliminates Onboard Gear Penalty: Frees internal airframe volume for cryogenic liquid hydrogen (LH2) propellant tanks and removes heavy hydraulic retraction actuators.
- Continuous Thermal Protection: Preserves an unbroken lower fuselage aerodynamic and thermal shield without landing-gear door seams.
- Kinematic & Release Engineering: Designed mechanical retention latches, shock-absorption kinematics, and synchronized release/capture mechanisms validated on active runways.
