Skyroot Aerospace test fires solid propulsion rocket stage Kalam-5
Spacetech startup Skyroot Aerospace has successfully test fired its solid propulsion rocket stage named Kalam-5. The company claims that this is first time for the private company to successfully design, develop and test a full solid propulsion rocket stage.
The Hyderabad-based startup also eyes to raise $15 million next year.
Naga Bharath Daka and Pawan Kumar, ex-ISRO scientists established Skyroot Aerospace to build private space launch vehicles. The Vikram series of the startup is named after ISRO founder Dr. Vikram Sarabhai and have three launch vehicles under it, specially made for launching small satellites.
Pawan Kumar Chandana Co-founder and CEO of Skyroot Aerospace, in an official statement said, "Kalam-5 is a demonstrator solid rocket propulsion stage with exactly the same propellant, materials, and interfaces as the three solid propulsion stages of the Vikram-1 launch vehicle."
The first vehicle, Vikarm-I is currently in manufacturing stage and is expected to be launched in December 2021 with ISRO’s help, he said.
The CEO added that this is the first of the five Kalam series of solid rocket motors. The other four motors are in the process of manufacturing and is predicted to be tested next year.
"It gives a peak Sea Level thrust of 5.3kN and designed to take 66 atmospheres and 30,000 C of combustion pressure and temperature respectively," Kumar said.
Kalam-5 is made of 15 diverse kinds of advanced material, nine manufacturing processes with zero moving parts.
“This is a major milestone for Skyroot and for the Indian private space sector. The test results closely matched our predictions and this success gives great confidence for our Vikram-I vehicle development,” Kumar said.
