Space Propulsion Structure Mechanics
and Analysis.
Analysis of space propulsion elements performed by Astrium's structure mechanics
team at Ottobrunn, Germany.
Experience
The structure mechanics team at Ottobrunn have gathered an impressive
portfolio of achievement that has extended beyond the structural
analysis of rocket
engines and satellite
thrusters. This experience includes the efficient structural
analysis of cryogenic
valves, satellite structures, propellant
tanks, solar generators, satellite antennas and helicopter pylons.

DISCIPLINES
Activities within the structure mechanics
department are centred around the main disciplines of finite element analysis,
many body dynamics, damage mechanics, stress analysis and actual testing.
The main activities performed under each of these disciplines are summarised
as follows:
Finite Element
- Model preparation (free or by using CATIA files).
- Linear statics Non-linear statics (buckling, contact, plasticity,
creeping).
- Dynamics (natural frequency, sine, random, shock, acoustics analyses).
- Optimisation.
Many-Body Dynamics
- Deployment of solar generators.
- Switching processes inside valves.
- Attitude control and simulation.
Damage Mechanics
- Load spectra.
- Service life, fatigue.
- Fracture mechanics, crack propagation computation.
Stress Analysis
Components, fasteners, riveting, bonding, soldering, welding, etc.
Structural Test
- Static load test.
- Vibration test (sine, random, shock, acoustics).
- Engine hot-fire tests.
- Material test.
