The Vikram 1 is a small-lift launch vehicle being developed by Skyroot Aerospace, an Indian startup aerospace company. This launch vehicle has a payload capacity to deliver 225 kg to 500 km SSO or 315 kg to 500 km LEO for launching small satellites. It aims to launch by end of 2022.[1][2] Its name is derived from the Father of Indian space program, Vikram Sarabhai.[3]

Vehicle Description[]

The Vikram-1 rocket has three solid fuel-powered stages each with a burn time ranging between 80 and 100 seconds and the final stage is Raman engine. The Raman engine is powered by UDMH and NTO liquid fuels in a cluster of four engines that generate 3.4 kN thrust. These Raman Engines will be used to do final adjustments in the orbit of the stage.[4] Vikram I is designed to lift 225 kg to a 500 km Sun synchronous polar orbit (SSPO) and 315 kg to 45º inclination in a 500 km low Earth orbit (LEO).[5][6]

Development and Testing[]

  • On 12 August 2020, Skyroot Aerospace successfully tested Vikram 1 launch vehicle's upper stage engine "Raman".[7]
  • On 21 September 2020, Several Ballistic Evaluation Motors (BEM) were fired to fine tune and qualify Vikram-1 Solid Stage Propellant formulation.[8]
  • On 22 December 2020, Skyroot conducted a successful test firing of a Solid rocket stage demonstrator 'Kalam-5'.[9] The test was conducted at Solar Industries in Nagpur at 3 pm. The test cleared a 24 seconds long duration demonstration, achieving a peak thrust of 5.3 kN.[10]
  • On 20 June 2021, Vikram 1's third stage (Kalam-100) successfully completed the Proof Pressure Test (PPT).[11]
