Liquid Propulsion System Center (LPSC), Bengluru
Liquid Propulsion Systems Centre (LPSC) is the lead Centre for development and realization of earth-to-orbit advanced propulsion stages for Launch Vehicles and also the in-space propulsion systems for Spacecrafts. The LPSC activities and facilities are spread across its two campuses viz., LPSC Headquarters and Design Offices at Valiamala/Thiruvananthapuram, and Spacecraft Propulsion Systems Unit at LPSC, Bangalore/Karnataka. LPSC is vested with the responsibility of design, development and system engineering of high performance Space Propulsion Systems employing Earth Storable and Cryogenic Propellants for ISRO’s Launch Vehicles and Satellites. Development of fluid control valves, transducers, propellant management devices and other key components of Liquid Propulsion Systems are also under the purview of LPSC.
LPSC Valiamala is the Centre Headquarters, responsible for R & D, System Design/Engineering and Project Management functions. The Fluid Control Components Entity and the Materials & Mechanical Engineering Entity are located here apart from the Earth Storable & Cryogenic Propulsion Entities, handling the core tasks of the Centre.
LPSC Bangalore focuses on satellite propulsion. Design & Realisation of Propulsion Systems, integration of spacecraft propulsion systems for Remote Sensing and Communication satellites, Development and production of transducers / sensors are other major activities at LPSC, Bangalore. Fabrication of launch vehicle stage tanks and structure at ASD/HAL is also coordinated and managed by LHWC at Bangalore.,

What is a liquid-propellant rocket engine?
A liquid-propellant rocket engine is a rocket engine that uses liquid propellants as its working fluid. The propellants are stored in separate tanks and are pumped into the combustion chamber, where they are ignited and burned. The hot gases produced by the combustion are then expanded through a nozzle to produce thrust.
What are the advantages of liquid-propellant rocket engines?
Liquid-propellant rocket engines have several advantages over solid-propellant rocket engines. They can be throttled, which means that the thrust can be varied during flight. This is useful for maneuvers such as orbit insertion and landing. Liquid-propellant rocket engines also have a higher specific impulse, which means that they produce more thrust for a given amount of propellant. This makes them more efficient for long-range missions.
What are the disadvantages of liquid-propellant rocket engines?
Liquid-propellant rocket engines have several disadvantages compared to solid-propellant rocket engines. They are more complex and require more maintenance. They also take longer to start and shut down. Liquid-propellant rocket engines are also more expensive than solid-propellant rocket engines.
What are the different types of liquid-propellant rocket engines?
There are two main types of liquid-propellant rocket engines: bipropellant engines and hypergolic engines. Bipropellant engines use two different propellants, such as kerosene and liquid oxygen. Hypergolic engines use two propellants that ignite spontaneously when they come into contact with each other, such as hydrazine and nitrogen tetroxide.
What are some of the applications of liquid-propellant rocket engines?
Liquid-propellant rocket engines are used in a variety of applications, including:
- Spacecraft propulsion: Liquid-propellant rocket engines are used to propel spacecraft into orbit and to maneuver them in space.
- Missile propulsion: Liquid-propellant rocket engines are used to propel missiles to their targets.
- Launch vehicle propulsion: Liquid-propellant rocket engines are used to propel launch vehicles into orbit.
- Aircraft propulsion: Liquid-propellant rocket engines are used to power some experimental aircraft.
What are some of the challenges of using liquid-propellant rocket engines?
One of the biggest challenges of using liquid-propellant rocket engines is the need to store the propellants in separate tanks. This can be difficult and expensive, and it also increases the risk of leaks. Another challenge is the need to keep the propellants at the correct temperature and pressure. This can be difficult to do, especially in the harsh Environment of space.
What are some of the future developments in liquid-propellant rocket engines?
One of the most promising future developments in liquid-propellant rocket engines is the development of new propellants that are more efficient and less toxic. Another promising development is the development of new engine designs that are more reliable and easier to maintain.
