The VLM (Veículo Lançador de Microssatélites) is a proposed three-stage satellite launcher being developed by the Brazilian General Command for Aerospace Technology in collaboration with Germany. The project originated in 2008 as a simplified version of the VLS-1 rocket, using only the core stages.

A version based on the S-50 rocket engine is being developed, with the objective of launching satellites of up to 150 kg into equatorial circular orbits at 300 km altitude.[2]

Development history

Development on VLM started in 2008 for the purpose of low-cost and reliable launch of microsatellites.[1] Initially, a four-stage rocket using solid fuel 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

It was later decided in 2011 to build a precursor single-stage rocket bearing a new engine called S-50. The vehicle is being developed and its engine tested in collaboration with the German Space Agency (DLR).[1][3] This precursor test is called VS-50 and is planned for launch in 2019.[4][5] The VS-50 vehicle measures 12 m (39 ft) long, 1.46 m (4 ft 9 in) in diameter, and has a mass of about 15 tons.[1]

All launches are planned to take place from the Alcântara Launch Center, located on Brazil's northern Atlantic coast.

VLX family

When the VLM design and tests are completed to satisfaction, it is planned to develop a larger rocket family called VLX, targeting the delivery of payloads of between 300 and 500 kg to low Earth orbit.[1] The VLX family will include two launchers named Aquila 1 (for delivery of 300 kg to 500 km) and Aquila 2 (for delivery of 500 kg to 700 km into a polar orbit).[1] An early concept calls for two lateral S-50 engines configured as strap-on boosters.[1] A new liquid fuel engine, called L-75, is being designed for this launcher family. [1] It is hoped that the maiden flight of Aquila 1 will take place in 2023, and that of Aquila 2 in 2026.[1]

VLM-1

The VLM-1 vehicle is designed to deliver up to 150 kg (330 lb) payloads to a 300 km equatorial circular orbit.[1] VLM-1 is projected to have a total mass of 28,000 kg (62,000 lb), including 10 tons of propellant.[2] The first two stages will use the S-50 solid fuel engine,[6] with the third using the same S-44 engine as in the VS-40 sounding rocket.

Stage 1: S-50 rocket engine
Stage 2: S-50 rocket engine
Stage 3: S-44 rocket engine

Planned versions

In the future, the L5 liquid fuel rocket engine will replace the solid 3rd stage engine. The configuration will be:

Stage 1: S-50 rocket engine
Stage 2: S-50 rocket engine
Stage 3: L5 rocket engine (to be developed)

Proposed flights

The qualification flight is VLM-1 (or XVT-00).[4]

#	Vehicle	Payload	Date	Launch site
1	VLM-1 (XVT-00)	Qualification	2019[4][7]	—
2	VLM V-01	SHEFEX III	2021[4]	—

gollark: That seems like a lot for a school project.

gollark: (also, this is probably more <#496135660831375370>)

gollark: (this isn't about a single actual physical molecule or something changing, but the genes for it changing slightly over time and producing different verisons)

gollark: I guess so. If you need, say, ten changes to an enzyme to bring it from one state to a much better one, but it works much worse/totally breaks while it's in the middle of both, it's hard for it to evolve to the better version.

gollark: If one what is stuck?
