AbstractA lifting body re-entry vehicle is one of the concept of re-usable Space Transportation System that Japan Aerospace Exploration Agency, JAXA, has been investigated. In this concept the vehicle generates lift force by its body without wings. The lifting body shape has some advantages such as superior volumetric efficiency and better characteristics against aerodynamic heating at hypersonic speed. On the other hand, the disadvantages such as its low lift-drag ratio, poor stability and controllability at low speed make it more difficult to land on a conventional runway. LIFLEX (LIfting-body Flight Experiment), a flight experiment using a small and law-cost vehicle, has been planned to accumulate the knowledge and skills for automatic landing technology for liftingbody re-entry vehicle.This report describes about the flight path planning and the guidance low design for LIFLEX vehicle. A flight reference trajectory and feed-forward command profiles were designed by executing an six-degree-of-freedom open loop flight simulation. And, onboard compensation was added to modify the trajectory and feed-forward commands to handle various separation conditions and steady wind conditions. The structure of guidance law is based on the PID controller. The guidance feed-back gains were designed using MDM/MDP approach. These are the same architectures as that of ALELEX. Finally, six-degree-of-freedom simulations including a nominal case and six off-nominal cases were performed and all cases are satisfied all the required conditions during the flight and at the touchdown point.
