The VLM (Veículo Lançador de Microssatélites) is a proposed Brazilian satellite launcher. The project originated as a simplified version of the VLS-1 rocket, using only the core stages.

Currently, a version based on the S50 rocket engine is being studied, with the objective of orbiting satellites up to 150 kg in circular orbits ranging from 250 to 700 km.

It will be a three stage rocket, expected to launch the SHEFEX III mission by the German Aerospace Center (DLR) in 2016.[1][2][3]

Configuration[edit]

Original VLS-1 derived[edit]

Initially, a four solid fuel rocket stages configuration was proposed, arranged in the following order:

  • Stage 1 - S-43 rocket engine
  • Stage 2 - S-40TM rocket engine
  • Stage 3 - S-44 rocket engine
  • Stage 4 - S-33 rocket engine

This configuration is related to the proposed VS-43 sounding rocket.

Current proposal (VLM-1)[edit]

Currently, the first two stages will use the new S50 12 tonnes[4] solid fuel engine, with the third using the same S-44 engine as in the VS-40 sounding rocket.[5] This configuration is related to the proposed VS-50 sounding rocket and known as VLM-1:[6]

  • Stage 1 - S50 rocket engine (to be developed)
  • Stage 2 - S50 rocket engine
  • Stage 3 - S-44 rocket engine

Planned versions[edit]

In the future, the L5 liquid fuel rocket engine will replace the solid 3rd stage engine:[5]

  • Stage 1 - S50 rocket engine (to be developed)
  • Stage 2 - S50 rocket engine
  • Stage 3 - L5 rocket engine (to be developed)
