PEGASUS specifications "MPLC"

The reusable MPLC or multi-purpose logistics carrier, named PEGASUS functions as a cargo carrier.  It`s designed to transport, protect, and support equipment and experiments in space.

The PEGASUS rocket booster is powered by the liquid propellant engine HTP3Z-1X  which provides about 3,8 ton of thrust at lift off. It runs on 85% H2O2 and Ethanol. The engine will burn for 110 seconds and consume 1,220 kg of propellant during flight!

  • Lift off mass: 1,820 kg

Why a rocket fuel pump?

The Sweden Rocket Research Group`s rocket fuel pump increases safety, reliability and performance while reducing cost and development time. The pump system uses only a few valves and pump chambers to achieve better performance than current rocket fuel pump designs today.

Easy To integrate
  • The rocket fuel pump is easier to integrate because it can be easily scaled up or down and still provide constant, controllable pressure, regardless of flow.
High Reliabilty
  • The pistonless pump is not susceptible to contamination, contains no sliding parts or lubrication, and may be started after extended periods of quiescence. Also the simplicity of the pump operating system reduces the risk of fluid cavitation during operation.
Increased Safety
  • The rocket fuel pump is easy to start up and shut down with no spool up time required.Unlike others Turbo pumps this have almost no moving parts, except 4 pcs ball valves that control the flow of liquid.
  • The pump uses inexpensive materials and processes in construction which can be easily scaled up or down, keeping engineering and test costs low.

Both pump chambers are alternatively pressurized with a preset gas pressure from delivery vessels that is mounted just above the fuel tanks.This system operated by a number of ball valves on the pumps top plate.
