Vihaan The Sounding Rocket lifts off and dazzles in the evening sky
IIST team, from VIHAAN, The Rocketry Club at IIST, competed in the IN-SPACe Model Rocketry Competition. Around 40 teams across India qualified for the competition, and only 20 could pass the flight readiness review and launch their sounding rocket, thereby welcoming Diwali in advance. IIST's team Vihaan also could launch their sounding rocket which was designed and built exclusivley by the student rocketeers of IIST. VIHAAN-02, as the team has named the rocket, is a sounding rocket which uses solid propulsion, specifically a K Class motor with an impulse of 1500 Ns. The rocket is 175 cm in length and weighs around 9kg without propellants. It boasts an incredible Length to Diameter ratio of 14, a truly unique one in the competition, which helps in the aerodynamic stability of the rocket. It uses a low-shock, spring-based ejection mechanism, which the team designed for this mission. Post-flight analysis confirmed an altitude above 1 km which is similar to the those predicted using simulations.
