Effect of Loading Densities in Closed Vessel Tests on the Burning Rate of a Propelling Charge

Pragati Mehta, Chandrakala P. Shetty, Ramesh N. Pundkar, Himanshu Shekhar

Closed vessel firing of gun propellant at different loading densities is conducted for evaluation of its ballistic parameters. Although in actual gun applications, loading densities are higher, but for closed vessel evaluation standard loading density is ... see more

Effect of Temperature on Mechanical Properties of Solid Rocket Propellants

Himanshu Shekhar

Mechanical properties of solid rocket propellants are dependent on temperature. Any change in temperature brings significant change in the tensile strength, percentage elongation, and elastic modulus of the propellant. Different classes of operational sol... see more

Assessment of Poisson's Ratio for Hydroxy-terminated Polybutadine-based Solid Rocket Propellants

Himanshu Shekhar, Anil D Sahasrabudhe

Poisson's ratio of hydroxy-terminated polybutadine (HTPB)-based composite propellant is estimated from uni-axial tensile testing. Double dumbbell specimens as per ASTM D638 type IV standard were used and Poisson's ratio at break, obtained by cha... see more

Studies on Stress-Strain Curves of Aged Composite Solid Rocket Propellants

Himanshu Shekhar

Mechanical property evaluation of composite solid rocket propellants is used as a quick quality control tool for propellant development and production. However, stress-strain curves from uni-axial tensile testing can be utilised to assess the shelf-life o... see more
