Indian Space startup, Skyroot Aerospace, has proven the crucial propulsion technology of their maiden rocket Vikram-1, with the latest test-firing of an engine. In August this year, the company had tested its liquid-fueled engine and now has proven the technology of the solid-fueled engine (Kalam-5), by successfully test-firing a miniature version. Solid motors or solid-fueled engines are high thrust, low-cost rocket engines with propellant in solid form. Simply put, a rocket is a combination of multiple engines (stages) that are vertically stacked. Kalam is a series of five solid-fueled rocket engines with a thrust ranging from 5kN to 1000kN (approx 100Tons).
