Hypersonic aircraft design [PDF]

A hypersonic aircraft is designed which uses scramjets to accelerate from Mach 6 to Mach 10 and sustain that speed for two minutes. Different propulsion systems were considered and it was decided that the aircraft would use one full scale turbofan-ramjet.

General method for prediction of thermal conductivity for well-characterized hydrocarbon mixtures and fuels up to extreme conditions using entropy scaling [PDF]

, 2019
A general and efficient technique is developed to predict the thermal conductivity of well-characterized hydrocarbon mixtures, rocket propellant (RP) fuels, and jet fuels up to high temperatures and high pressures (HTHP).

Advances in phase stabilization techniques of AN using KDN and other chemical compounds for preparing green oxidizers

Defence Technology, 2019
Research and development of green oxidizers and green fuels as a possible replacement for ammonium perchlorate (NH4ClO4, AP) and hydrazine (N2H4) respectively has been increased considerably in the recent years. AP and hydrazine are the oxidizer and fuel

Experimental investigation of erosion rate of insulation materials using hybrid rockets

FirePhysChem, 2021
Thermal insulation is essential to protect the exposed surface from high-temperature and high heat flux situations. The selection of suitable insulation materials plays a crucial role in determining rocket performance.

On Maximum Evaporation Rates of Liquid Droplets in Rocket Motors [PDF]

, 1953
Upper limits have been estimated for the rate of evaporation of small liquid droplets in representative rocket combustion chambers. The droplets are assumed to be isothermal at all times. The droplet temperature as a function of time is determined by an

Additive Manufacturing of High Solids Loading Hybrid Rocket Fuel Grains [PDF]

, 2018
Hybrid rocket motors offer many of the benefits of both liquid and solid rocket systems. Like liquid engines, hybrid rocket motors are able to be throttled, can be stopped and restarted, and are safer than solid rocket motors since the fuel and oxidizer ...
