L&T Defence has been associated with India's Space Programme since 1975 - from the SLV-3 to the current GSLV. Our offerings include rocket motor casings, convergent and divergent nozzles, titanium gas bottles for liquid stages, titanium tanks for liquid upper stages, heat shield, core base shroud and inter-stage assemblies for launch vehicles as well as solar array deployment mechanisms and reflector deployment mechanisms for satellites.
Over the last 3 decades, L&T Defence has manufactured motor casings, convergent and divergent nozzles, gas bottles for liquid stages, tanks, heat shield, core base shroud and inter-stage assemblies for various launch vehicles using exotic materials.
L&T Defence has experience in manufacturing satellite mechanisms such as Solar Array Deployments Mechanism & Reflector Deployment Mechanisms.
The solar array deployment mechanism is used to stow solar panels to the satellite body during launch and provide smooth, controlled deployment once the satellite is put into orbit. The deployment energy is stored in the springs while the pyro-actuated device cuts the cable on ground command. The mechanism is assembled in a dust free, humidity and temperature controlled environment.
The antenna reflector deployment mechanism is one of the most important systems in the satellite, and is used for communication purposes. Antenna reflectors are kept stowed on the spacecraft body during the launch and are deployed after the satellite reaches its final orbit by ground command.
L&T Defence has experience in installation and commissioning of Aerodynamic Test Facilities which can be used for aerodynamic and aero-thermal characterization of launch vehicles and missiles. The facility can simulate actual conditions for testing of the launch vehicles and missiles
