The VS-40 (Foguete Suborbital VS-40) is a Brazilian sounding rocket using solid fuel and stabilized aerodynamically.

The original version, VS-40, uses the S-40TM (4,200 kg) first stage engine and the S-44M (810 kg) second stage engine.[2][3][4] This configuration corresponds to the upper stages of the VLS-1 rocket.[5]

Version VS-40M used a S-40M engine for the first stage.[4]

Flights

[edit | edit source]

VS40 performed the following flights:[4][6][7][8][9][10][1][11]

Date Version Flight Site Mission
1993/04/02 VS-40 V01 Alcântara Operação Santa Maria - Qualifying flight for the S44 engine. 760 seconds in micro-gravity.[4]
1998/03/21 VS-40 V02 Alcântara Operação Livramento - VAP-1 (Fokker) payload.[12]
2012/06/22 VS-40M V03 Andøya SHEFEX (Sharp Edge Flight Experiment) II payload.[9][10]
2015/11/13 VS-40M Alcântara Operação São Lourenço - SARA Suborbital 1 (reentry experiment) – Failure (exploded on pad) [6][7][8][1][12]

A flight of VS-40M carrying "SARA Suborbital 2" was planned but eventually cancelled. A future flight of VS-40M carrying HIFiRE 8 is in development.[4]

S-40 rocket engine

[edit | edit source]

The S-40 is a solid-propellant rocket motor developed and manufactured by Avibras Aeroespacial, a Brazilian aerospace company, primarily for use in sounding rockets. Different versions were used on several rockets:[4]

  • S-40 - first stage of Sonda-4;
  • S-40TM - first stage of VS-40; third stage of VLS-1;[5][13]
  • S-40M - first stage of VS-40M; second stage of VLM.

S-40TM specifications:[13]

[edit | edit source]
  • Total mass: 5664 kg
  • Unfueled mass: 1212kg
  • Thrust: 208.39 kN
  • SI: 275 seconds
  • Burn time: 56 s

S-44 rocket engine

[edit | edit source]

The S-44 is a solid-propellant rocket motor developed by the Instituto de Aeronáutica e Espaço (IAE), part of Brazil’s Departamento de Ciência e Tecnologia Aeroespacial (DCTA).[14] It was used as second stage of VS-40 and VS-40M; the third stage of VLM and the fourth stage of VLS-1.[4]

S-44 specifications:[14]

[edit | edit source]
  • Total mass: 1025 kg
  • Unfueled mass: 190 kg
  • Thrust: 33.24 kN
  • SI: 282 seconds
  • Burn time: 68 s
