In an official statement, the startup revealed that its solid propulsion rocket stage has been
built with advanced carbon composite structure in a completely automated process. Carbon composite case is five-times lighter than steel case but is also very challenging to design and manufacture.
“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. 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,” Pawan Kumar Chandana Co-founder & CEO of Skyroot Aerospace, said in a statement.
