2 Project Overview 2 From 3 rd Fp7 Space Call Grant Agreement n Start date: 1 st March 2011 Planned duration 3 years Project Coordinator: Thales Alenia Space Italia (Business Segment Space Infrastructures & Transportation Torino) Project Partners: UNIVERSITA degli STUDI PADOVA Italy NAMMO RAUFOSS AS Norway BRADFORD Engineering BV The Netherland POLITECNICO di MILANO Italy Vysoke uceni technicke v Brne Czech Republic GMV Aerospace and Defence SA Spain STUDIEL France

3 Scope 3 Aimed at the development of a new throttling propulsion technology enabling a Lander to perform a soft and precision landing on a planetary surface, and a new low-cost highly realistic test bed to qualify precision landing capability on ground. The Hybrid propulsion technology has been selected, because of its peculiarities (safety, minimum environmental impact, low life cycle costs, responsiveness, competitive performances, increased reliability, soft ignition and shutdown). The landing test requirements are derived from the soft and precision landing requirements on the mars planet surface (i.e. Exomars and Mars Sample Return missions), adapted to the earth environment and to the proposed test specific objectives.

4 Objectives 4 Focuses on three major objectives, that are the key to achieve the soft and precision landing capabilities: Engine design, specific for throttling functionality, Oxidizer throttable device development, Design of the landing case: test bench and testing procedures.

5 Expected Results 5 SPARTAN Project expected results are aimed at enabling soft and precision landing capabilities on Mars by: Development of an innovative engine design, specific for throttling functionality, Development of an oxidizer throttable device, Design of the landing case including test bench and testing procedures. Perform the demonstration of these high level technologies making the first, but horizontally extended, step up to the throttable propulsion capability. Demonstrate the first European soft landing drop test, by means of a throttable engine and of a Lander module, autonomously guided. It is expected that these results will trigger an upstream research aimed at improving, in the long-term, the capability for access to planet surfaces in the frame of Space Exploration activities.

12 Main Results Achieved 12 A specific regression rate measurement device has been designed and tested; the measurement device foreseen in the proposal was supposed to be acquired from the US but this is no longer available for the external market. This is an important added value brought by the project since no such device existed in Europe. Advanced Coding: a CFX code has been developed and extensively used to support the engine design, allowing the engine and engine injection design optimisation (leading to L/D optimization). A detailed design of the Flow Control valve has been carried out and the breadboard model is now being manufactured for verification testing.

13 Main Results Achieved The preliminary Flight Dynamics System design has been performed, allowing for detailed requirements definition and mission profile characterization. GNC components have been selected and preliminarily tested. After a preliminary test aimed at consolidating the test plan for the Throttable Engine validation campaign, an additional representative test in preparation for the validation campaign has been planned and specified. This will be performed with a dummy structure to verify and validate the recovery system, the aerodatabase and the helicopter wake effect. 13
