Study of a thrust vectoring system for rockets through a pressurized air test bench
, 2017 Aiming to be the first step towards the design of a fully operational stabilization system for rockets, thebuilding of a model is done representing the attitudeof a rocket with anactive stability system. Several tests are done with the model both static and dynamic with different type of sensors that give us a view of the response of the system to ...
