Performance of Fuel-Rich Propellants for Ramjet Applications

Autor: P. G. Shrotri, V. K. Bhat, Haridwar Singh, R.H. Brahmbhatt

Publikováno v: Defence Science Journal. 46:331-336

A hydroxy terminated block copolymer-based fuel-rich propellant has been studied for gun and missile applications. The copolymer has shown certain advantages over hydroxy terminated polybutadiene. Zirconium was found as a promising metal fuel.

Effect of gamma radiation on hydroxyl terminated polybutadiene-base elastomers loaded with ammonium perchlorate

Autor: P. G. Shrotri, P. B. Navle, V. G. Dedgaonkar

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 187:1-8

Composite elastomers containing varying amounts of ammonium perchlorate (AP), hydroxyl terminated polybutadiene (HTPB) and toluene-di-isocyanate (TDI) with NCO/OH ratio unity were synthesised by γ-radiation over a dose range 0–720 kGy. To understa

Properties of hydroxyl-terminated polybutadiene-base elastomers under the influence of γ-radiation

Autor: P. G. Shrotri, V. G. Dedgaonkar, P. B. Navle

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 176:153-160

Following radiation treatment, a number of polyurethane samples were synthesized from hydroxyl-terminated polybutadiene and toluene diisocyanate: the equivalence ratio of NCO/OH was varied over 0–2.0 and the γ-dose over 0–720 kGy. Understanding

Diol-diisocyanate polymerization by gamma irradiation

Autor: V. G. Dedgaonkar, P. G. Shrotri, P. B. Navle

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Letters. 176:77-84

Gamma irradiation has been used as an alternative way of curing diol-diisocyanate by means of specific catalysts and/or elevated temperatures. A mixture of toluene diisocyanate (TDI) and hydroxy terminated polybutadiene (HTPB) oligomer were irradiate
