Comprehensive rescue system for the "FLARIS LAR1" aircraft - Phase II

The aim of the project is to develop a comprehensive redundant rescue system based on a parachute and safety cushions for the FLARIS LAR1 aircraft, ensuring safe landing/earth impact in the event of an engine failure occurring during a regular operational flight. As part of the work financed to date from the Smart Growth Operational Programme, Tasks 1, 2 and 4 have been fully implemented, thus achieving key project milestones parameterizing the developed prototype of an adaptive rescue parachute for the entire aircraft, providing gradual adjustment of the canopy area from 4 m2 to 184 m2, ensuring a descent speed of no more than 9.5 m/s. The validity of the system operation was also confirmed, i.e. parts of the subsystems of the container release mechanism, suspension covers, rocket system mounting elements and correct safe release of the rocket and parachute above the aircraft structure. The parameter confirming the KM is throwing the parachute at a distance of at least 2 m beyond the outline of the aircraft's vertical stabilizers. A reinforced central part of the fuselage structure was also designed, i.e. a duralumin space frame, which ensures optimal strength of the attachment points (parachute suspension fittings). The parameter confirming KM is the lack of plastic deformation of the attachment nodes). The above was achieved thanks to the implementation of Task 4, the aim of which was to develop prototypes of auxiliary systems, i.e.: 1. Aerodynamic braking system for the aircraft at speeds from 760 km/h to 300-250 km/h using: on-board computers and aerodynamic brakes. 2. Optimized landing gear ensuring safe, controlled deformation of the legs in critical conditions (emergency touchdown). 3. Prototypes of the cabin, fuel tank and center wing guarantee the safety of the crew at the moment of aircraft collision with the ground. 4. Optimized landing gear ensuring safe, controlled deformation of the legs in critical conditions (emergency touchdown). 4. Seat prototype. As part of the European Funds for Modern Economy program, the implementation of Tasks 3 and 5 is planned, which will end with the achievement of the remaining milestones and will ultimately lead to obtaining an aircraft with TRL9 readiness equipped with all systems designed and manufactured in stages 1-4, in the cockpit of which there will be control devices along with full visualization of the readiness of the subsystems. The final effect of the project will be an aircraft equipped with rescue systems with the following parameters: - take-off weight = 1700 kg, - cruising ceiling = 7620 m, - free fall speed on a parachute - below 28 km/h. The division into two phases does not affect the achievement of the original goals planned for the entire project, including the implementation of R&D results in business activity. Both the milestones planned to be achieved in individual tasks and the main result of the project in the form of an aircraft equipped with rescue systems at TRL level 9 remain unchanged. Phase II of the project is consistent with the specific objective in Priority 1. FENG, i.e. Developing and strengthening research and innovation capabilities and using advanced technologies. The work planned in Phase II of the project consists of carrying out industrial research and development work, therefore it is consistent with the scope of support provided for in the SMART Path action in FENG.
