Abstract This paper summarizes the abort recovery strategy for future vertical landing spacecraft in case of single engine failure, by applying state-of-art non-linear control law. The abort recovery strategy applied to future vertical landing systems with multiple engines are composed of two approaches. First is to shutdown the counter engine of the failed engine in order to minimize the attitude perturbation. And the second, which is the key approach, is applying a nonlinear control law. Such an approach has the robustness to the large attitude motion, and also to the variation in weight, moment of inertia and center of gravity. The control law applied has been developed under the collaboration with Nagoya University. To demonstrate the above mentioned strategy, Mitsubishi Heavy Industries is preparing flight test by a subscale demonstrator called “OEEX”, which stands for “One Engine inoperative EXperimental vehicle”. The results of application of such strategy are described. Also, the status of the OEEX is presented.

Highlights • We model the abort recovery strategy applied to future vertical landing systems. • The abort recovery strategy includes a state-of-the-art non-linear control law. • Simulation results show that the abort recovery strategy works well. • We are preparing to demonstrate the strategy with a sub-scale prototype.
