Skyroot Aerospace test-fires advanced fully 3D-printed cryogenic engine
In Nagpur, private space vehicle company Skyroot Aerospace test-fired its 3D-printed Dhawan II engine for a duration of 200 seconds on 4 April.
An overview of the news
This is the second cryogenic rocket that has been successfully test-fired by Skyroot, following the Dhawan-I engine that was tested in November 2021.
The achievement comes after the November 2022 launch of Vikram-S, making Skyroot the first Indian private company to send a rocket into space.
The engine has been developed by the company for its heavy vehicle Vikram II.
This cryogenic engine will be used as an advanced stage of the updated version of Vikram-II.
The cryogenic engine series is named after Dr. Satish Dhawan, a renowned Indian rocket scientist who played a key role in the development of the Indian space programme.
Utilisation of Skyroot’s cryogenic rocket engines
Skyroot's cryogenic rocket engines use two high-performance rocket propellants, liquefied natural gas (LNG) and liquid oxygen (LOX), which require cryogenic temperatures (below -150 °C) for storage and operation .
Fully cryogenic engines are ideal for rocket upper stages due to their high specific impulse, which increases payload carrying capacity.
Skyroot Aerospace is a spacetech start-up that aims to address growing concerns in the global space industry.
It provides low cost launch solutions to reach space in short time.
The startup's three launch vehicles - Vikram I, II and III - can carry payloads ranging from 200 kg to 700 kg to low Earth orbit.
Currently, the team is testing a 3D printed liquid propellant engine and a fully composite (carbon fiber) and high-performance solid rocket motor.
