Rockets are systems and need be designed & engineered as a system.ArjunPandit wrote:question related to what Ramana guru mentioned
will composite casings help in this case or they only help to reduce the mass?ramana wrote:When range is increased by reducing weight if the payload the accelerations increase. This makes the entire vehicle design subject to new loads and environments. And higher accelerations could lead to structural changes.
Rocket science, not art.
Elemental (Component) refinement is first step of evaluating first order approximation possibilities. Based on requirements, after picking up candidate alternatives one does multiple iterations of system design, before picking up best option and then do engineering development process.
The reduced payload requires perticular attention to payload subsystem sustaining very high peak acceleration by solidfuelled second stage at burnout time.
Those figures are closely guarded numbers that potential challanger agencies would die to know.
