Take-off and landing using ground based power - landing simulations using multibody dynamics

Abstract

A novel take-off and landing system using ground based power is proposed in the EU-FP7 project GABRIEL. The proposed system has the potential benefit to reduce aircraft weight, emissions and noise. A preliminary investigation of the feasibility of the structural design of the connection mechanism between aircraft and ground system has been performed by simulating the landing procedure on a moving ground system. One of the key challenges is the landing on a moving ground system under high crosswind conditions. The main focus in the current research is the calculation of the impact loads on both aircraft and ground system for a wide range of landing conditions (sink rate, velocity differences between aircraft and ground system, etc.). For comparison, conventional landing procedures with a traditional landing gear have also been simulated. Two different aerodynamic models (empirical and vortex lattice method) have been used and compared in the simulations for verification and validation purposes. The results of this research study are a set of load cases and operational constraints that can be used for the structural design of the ground system and modifications to the aircraft. Detailed values are presented in the paper. Key word

Assessment of Sub-scale Designs for Scaled Flight Testing

“…It has been used in a variety of research studies to investigate the flight mechanics of novel aircraft configurations such as a blended wing body [6,7,18], a box-wing aircraft [19,20] and a propulsive tail empennage concept [15]. Studies have been performed to assess the loads encountered during advanced take-off and landing procedures [21,22]. Finally, in case real-time simulations are required with a pilot in the loop, the simulation output can be cast to the Flight Gear open-source simulator † visual display system.…”

Magnetic levitation assisted aircraft take-off and landing (feasibility study – GABRIEL concept)

“…The developed simulation models [76][77][78] have two major parts. One of them includes (i) the pilot module, (ii) the flight control system, (iii) the aerodynamic model and (iv) the power plant simulation.…”
