The project
E-LISA is a research project aimed at developing, manufacturing, testing, and qualifying an innovative Iron Bird for integration tests of landing gear electro - mechanical actuator and brake for small aircraft transport applications.
Tests will be performed able to reproduce in a realistic and comprehensive way the landing gear operational cases, defined by certification specifications and topic leader requirements.
The Iron Bird will consist of a multi-functional intelligent test facility integrating hardware and software allowing performing all the tests and analyses perceived as fundamental to demonstrate the maturity of an electro-mechanical landing gear, hence paving the way for its implementation in a small transport aircraft.
The activities addressed by E-LISA aim to push the integration of electrical technologies to a further level of complexity and maturity than currently available, so as to drastically de-risk their integration on future products and contribute to achieve the permit-to-fly.
Key features
- Use of innovative modular design architectures and cost effective technologies:
- Modular architecture, allowing testing of either main, or nose landing gear
- Modularity in terms of capability of integrating different types of main and nose landing gears of different small transport aircraft
- Modularity in terms of capability of being integrated in more complex Iron Birds
- Reproduction of aircraft inertia, aerodynamic forces and runway characteristics
- Hardware and software in the loop testing
- Development of a methodology suitable for deep learning from big data obtained from the test campaign
- Validation and fine tuning of prognostics and health management algorithms and of failure models, facilitating the maintenance paradigm change from "scheduled" to "condition based"
All together, these key features will contribute to advance the Iron Bird technology beyond the current state-of-art

Significant Iron Bird innovations |
- Real-time application of loads
- Contact between landing gear wheel and runway simulator with a controllable vertical approach speed
- Possibility of reproducing the contact between wheel and runway with different roughness and irregularities of the runway, and to create wet conditions
- Realistic physical reproduction of the whole deceleration phase for landing (or acceleration for takeoff) by use of a high-fidelity real-time simulation model of the aircraft and of a speed controlled runway simulator, which actually embeds the effect of the aircraft inertia in the longitudinal direction
- Possibility of running tests representative of different aircraft weights and different landing (or takeoff) speeds
