Propulsion Design Engineer

The propulsion department is responsible for the R&D, conception, design, analysis, test planning, launch and in-orbit support of spacecraft propulsion systems. Typically components such as engines, valves and tanks are procured from external suppliers, they are assembled into the systems at Stevenage and then tested at various sites across Europe. This is all prior to support provided for the launch campaigns at sites around the world. Technical expertise is then provided for the subsequent on-station or in-flight operations.

Design Tasks

The propulsion design engineer will perform the role of a Propulsion Architect. From a mission plan a system must be generated to meet the requirements specified. The propulsion architect must be in touch with industry standards and technology in order to generate the system concept.
They will be then responsible for the component selection, system analyses and the generation of the associated documents for proposals, PDR, CDR, FDR, In-flight reviews.

Typical document sets are summarised below;

R&D Technical Studies and associated reports
System and Component Specifications
System analyses: encompassing pressurant analysis, propellant tank capacity, main engine performance, propellant loading, pressure drop and residuals analysis
Design Reports
Statements of Compliance
Test Plans and Requirements together with assessments and risk analysis

These analyses require familiarity with gaseous and liquid pressure drop theory for pipes, components and orifices, thermodynamic properties of gases including propellant vapour effects and phase properties of liquids, vapours and gases. For some analyses the engineer will be using existing code. In other cases it may be necessary to perform analyses from first principles. An ability to write code for new software models and to update existing software models (Visual Basic, Delphi, Java and C++) is desirable.

The engineer will have to give guidance to 3D CATIA engineers in order to generate the propulsion system mechanical layout, detailed drawings, bills of materials and documents for manufacture. The engineer will also have to work with manufacturing during the build phase to resolve problems as necessary. Manufacturing processes are mainly related to the forming and welding of small bore titanium alloy pipework manifolds, construction of sub-assemblies and the integration of systems. Familiarity with this type of manufacture and contamination control below 50µ would be of benefit.

The company use separate departments * specialists in the thermal control, product assurance * quality assurance, electronics (High Rel) stress and fracture analysis and FMECA*reliability fields, but the propulsion engineer requires an awareness of all these disciplines and be able to review these analyses. The propulsion engineer must also understand the rudiments of statistics.

The propulsion design engineer has to be able to review the design principles used in the externally provided components. This is necessary to understand testing philosophy, to review supplier s documentation, to assess whether the item is suitable for flight (qualification) and diagnose problems. It requires the ability to understand mechanical and electro-mechanical devices such as filters, pressure regulators, check valves, solenoid valves, latch valves, pressure transducers, pyrotechnic valves, pressure vessels (350 bar) and monopropellant* bipropellant rocket engines.

The engineer presents the propulsion system design to customers with the use of presentations and formal design review packs and meetings. Similarly the engineer has to agree * accept test results from the various phases of build (subsystem*spacecraft) and where necessary defend these at customer delivery reviews.

Support spacecraft testing, launch and operation. This role involves interfacing with engineers from related disciplines (i.e. thermal, structure, harness, S*C system, Assembly Integration & Test) and will involve meetings with customers.
Following launch, monitoring of spacecraft operations and investigations of anomalies if necessary. With component suppliers, testing facilities and launch sites spread throughout the world it may be necessary for the propulsion engineer to travel.

Management Tasks

The management of work package schedule and costs utilising the company software.

Skills Required

PC Skills; Matlab and most Microsoft Packages including Word, Excel, Powerpoint and Access.
Programming Skills: Visual Basic, HTML, Delphi, C++ and Java would be beneficial.
Presentation skills, verbal and written communication.
Understanding of fluid physical properties, fluid flow and gas thermodynamics.
Awareness of mechanical properties of elastomers, plastics and metals.

Qualifications

Degree subjects Maths* Physics* Mechanical, Aerospace or Aeronautical Engineering or relevant experience in lieu

Successful candidates will be required to be security cleared prior to appointment.
