### Rocket Engines

Skyroot Aerospace has produced several different classes of Rocket Engines for each of their rockets.

#### Earth-storable rocket engine
##### Raman-1

In August 2020, Skyroot first came into the limelight when it test-fired the Raman-I (named after C. V. Raman) hypergolic-fuel upper stage engine. This liquid-fuel upper stage is a component of Vikram-I and Skyroot was the first Indian private entity to test such an engine.

#### Solid rocket motor
##### Kalam-5

On 22 December 2020, Skyroot tested the solid-fuel rocket engine Kalam-5 (named after A. P. J. Abdul Kalam), the first of five planned carbon-composite Kalam rocket motors which are expected to power its launch vehicles. The test happened in Nagpur at a private test facility owned by Solar Industries, which is also an investor in Skyroot. In the name "Kalam-5", the 5 refers to the peak sea level thrust of 5.3 kN. The final engine in the series will be four times the size of Kalam-5.

##### Kalam-100

On 19 May 2022, Skyroot announced the successful completion of a full duration test-firing of its ‘Vikram-1’ rocket stage, representing a major milestone for the company. Named ‘Kalam-100’ after former president and the renowned Indian rocket scientist A.P.J. Abdul Kalam, the third stage of ‘Vikram-1’ produces a peak vacuum thrust of 100 kN (or ~10 Tons) and has a burn time of 108 sec. The rocket stage has been built with high-strength carbon fiber structure, solid fuel, novel thermal protection system, and carbon ablative nozzle. This testing will help Skyroot in development of orbital vehicle Vikram-1 and gives great confidence for the other rocket stages planned to be tested soon. This is largest rocket stage ever designed, manufactured, and tested completely in the private sector. There was a good match of test results with the design predictions in the very first attempt, which is a testimony to the team's capabilities. The state-of-the-art technology like carbon composite case, high propellant volumetric loading up to 94%, lighter EPDM based thermal protection system, and submerged nozzle have been validated through the successful static test.

#### Cryogenic rocket engine
##### Dhawan-1

On 25 September 2020, Skyroot Aerospace unveiled the Dhawan-1 (named after Satish Dhawan) upper stage cryogenic engine that will power heavier-lift systems such as Vikram-II. This is the first cryogenic engine in India that will use liquefied natural gas (LNG) as fuel; this fuel has the advantages of being clean, renewable and suited for long duration space missions. Dhawan-1 is 3D printed and designed with a regenerative cooling configuration.
Skyroot successfully test fired India's first privately developed small cryogenic engine called Dhawan-1 running on liquefied natural gas (LNG) and liquid oxygen (LOX) with pressure-fed engine cycle on 25 November 2021. It was a technology demonstration experiment for the upper stage of Vikram-2 rocket that is under active development. Solar Industries provided the test site. The engine made by 3D printing process and using super alloys.
