The first step of the study consists in choosing the vehicle you will work on: either vehicle 1 for local suborbital flights, vehicle 2 for high-speed long-range suborbital transportation or vehicle 3 servicing low Earth orbit.
Note than for type 1 vehicle, the study can deal with the "generic" sub-orbital vehicle described hereafter, focusing on the “propulsion” aspects, or it can be dealing with a sub-orbital vehicle studied previously by other student team. The study will be done by taking care of the minimization of environmental impacts from the solutions proposed, as well as to the maintainability induced by the need for “reusability” of the rocket propulsion system. It is welcome to refer to, and pursue, work done by previous teams.
You will address one of the following topics:
Propulsion system:
Or
Analysis of take-off phase of a suborbital vehicle using an innovative technological system (for example: magnetic rail Maglev type, other solution, ...) for assistance to the foreseen on-board propulsion, and of the benefit / constraints that it brings to vehicle design and performance
Or
Input data: the analysis shall be done by taking into account a needed control torque of 1200Nm around each of the 3 control axis of the vehicle, and a total duration (cumulated) of operating , for each control axis, of 100s.
Definition: the wording “Propulsion system” means the whole system delivering a propulsive force, and it encompasses: Rocket Engine(s), propellant and fluid Tanks, the propellant Feeding Circuit, the Pressurization System, the Loading/Unloading circuits, the propulsion system Controller, all other elements necessary for the proper operating of rocket propulsion.
