Engineering:Vikram-II
Vikram-II (Sanskrit, lit. Brave; Namesake: Vikram Sarabhai) is an under-development Indian small-lift launch vehicle being developed by Skyroot Aerospace.
The rocket will use a cryogenic upper stage powered by the Dhawan-series rocket engine and is intended for launching small satellites into low Earth orbit (LEO) and Sun-synchronous orbit (SSO).
Development
Vikram-II was announced by Skyroot Aerospace as part of its family of orbital launch vehicles following the successful suborbital launch of Vikram-S in November 2022.[1]
The vehicle is being designed as a heavier variant of the Vikram launch family and is expected to feature multi-orbit deployment capability. In September 2020, Skyroot unveiled the Dhawan-1 cryogenic engine, intended to power heavier launch systems such as Vikram-II.[2] In November 2021, the company successfully test-fired the Dhawan-1 engine using liquefied natural gas (LNG) and liquid oxygen (LOX), describing it as a technology demonstrator for the Vikram-II upper stage.[3]
Skyroot later conducted endurance tests of upgraded cryogenic engine variants, including fully 3D-printed configurations for future launch vehicles.[4]
