Traditional VTOL aircraft face challenges with fuel efficiency, range, and performance during horizontal flight due to high power requirements for vertical take-off and landing. These issues result in limited speed and autonomy. Transitioning from VTOL to horizontal flight is inefficient and safety risks are elevated due to the lack of redundancy and precise control during critical phases like take-off and landing.
Core Features
This hybrid propulsion system integrates the strengths of VTOL and fixed-wing aircraft through the following features:
- Hybrid Propulsion: A combination of four electric ducted fan (EDF) engines for VTOL mode and four turbofan engines for horizontal flight.
- Engine Articulation: Turbofan engines tilt between vertical and horizontal positions, enabling smooth transitions.
- Independent Control: Separate systems manage EDF engines for precision during take-off/landing and turbofans for long-range, high-speed cruise flight.
- Dual Navigation and Control: A redundant system ensures safety by independently managing propulsion systems.
- Energy Optimization: EDF engines deactivate during cruise flight, and their battery energy is partially recovered through turbofan generators.
Benefits
The system offers enhanced efficiency by combining precise control during VTOL and long-range capabilities in horizontal flight. Its dual propulsion setup increases safety, allowing continued operation even if one set of engines fails. The hybrid design reduces fuel consumption and improves flight autonomy. By transitioning smoothly between flight modes, the aircraft achieves the speed and range of fixed-wing planes without the need for a runway. This innovative approach delivers versatile and efficient VTOL aircraft with improved safety, performance, and operational flexibility, meeting modern aviation demands.
