Project Title: Consultancy for Design and Analysis of Sabot for Effective Separation
Project Description: Sabot is a very general term for projectile objects very commonly used to guide a projectile during its launch to avoid direct interaction between the projectile surface with that of holding component in a launcher, mainly canister. The design of sabot needs optimization of parameters and form for efficient separation action without interference with projectile and launcher vehicle for both of jump and fly-off behavior. Both mode of separation will be analyzed such that final design proposals may be made. Apart from the dynamic behavior of Sabot the issue of material including elastomeric element and friction at the contact surfaces should also be addressed.
