Simulation Environment for Development of Unmanned Helicopter Automatic Take-off and Landing on Ship Deck

Helicopter take-off and landing operations on ship carrier are very hazardous and training intensive. Guidance, Navigation and Control algorithms can help pilots to face these tasks by significantly reducing the workload and improving safety level. Anyway, the design and verification of such algorithms require the availability of suitable simulation environments that shall be a trade-off between simplicity and accuracy. This paper presents the simulation models developed to support the design, pre-flight verification and validation of helicopter trajectory generation and tracking algorithms for automated take-off and landing on a frigate deck. The process for generation and testing of the code to be integrated into the real-time Software-Inthe-Loop simulator is also described. Such fast time and real-time simulation environments contributed to reduce algorithms design time, risks and costs, by limiting the required flight test activities. Take-off and landing algorithms developed by using the proposed simulation environments were successfully demonstrated in flight.
