The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...

In this paper, we use a combination of experiment and simulation to achieve enhanced levels synthetic control on the microstructure much-used binder material hydroxyl terminated polybutadiene (HTPB).

Abstract In this study, the mechanical response of HTPB propellant grain under ultra-high loads is investigated. The low, intermediate and high strain rate uniaxial compression tastings (1.7×10 −4 ~3×10 3 s −1 ) hydroxyl terminated polybutadiene (HTPB) at room temperature were carried out by using universal testing machine split Hopkinson pressure bar (SHPB) system, respectively. tests cellular...

Hypersonic air breathing propulsion system has been in the minds of human being for a very long time. Ramjet propulsion provides efficient operation along with very high specific thrust and is very attractive for gun launch ramjet projectiles, hypersonic cruise vehicles and hypervelocity missiles. In the present investigation, Zr based fuel rich propellants in NC-NG matrix and HTPB matrix were ...

This manuscript presents an ultrafast-laser-absorption-spectroscopy (ULAS) diagnostic capable of providing calibration-free, single-shot measurements temperature and CO at 5 kHz in combustion gases low high pressures. Additionally, this was extended to provide 1D, a propellant flame. A detailed description the spectral-fitting routine, data-processing procedures, determination instrument respon...
