This effectively reduces leakage of propellant while enhances the safe- ty of aerosol products by avoiding propellant leakage during production, transportation and usage.

Casting the propellant is done through the "bayonets" from the casting pot to the case.

Flow in injector passages of a variable thrust liquid propellant rocket engine was studied.

The result shows that coating boron can be reduced the viscosity of boron-based propellant greatly.

Some stratification exists in the spray produced by any liquid propellant injector.

Two minutes later, after consuming 1.4 million pounds of solid propellant, the rocket burned out.

Viscous flow patterns are set up in the motor, increasing heat transfer to the propellant surface through greater mass transfer.

Input is simply a list of propellant ingredients, as well as chamber pressure and nozzle exit pressure.

This method can quickly and accurately check and diagnose the potential fault of the liquid propellant store and transport, which would be benefit for liquid propellant safe store and transport.

Its can be applied to evaluate the harmfulness of the liquid propellant rocket explosions for the space vehicle launching site.

Rocket propellant has barely changed in the more than 50 years since the launch of the first artificial satellite Sputnik.

The propellant is very hygroscopic and as such is sealed in a plastic bag and stored in a freezer.

The paper studies the influence of propellant thickness on the interior ballistic performance of an equilibrium launcher, such as, probable error of muzzle velocity, maximum pressure.

Accroding to the principle of low temperature sensitivity charge (LTSC), the application test of LTSC of nitramine propellant in the large middle caliber gun was analysed.

To reduce the mass of the propellant management device and the screen area used, the design was aimed to use the minimum mass to meet the requirement.

As control force source, the solid propellant gas generator was used to exert lateral force for the end control and the turn of vertical launching of missiles.

To achieve the right mixture of propellant, the patent presents a hybrid rocket motor that would use 3-d stereolithography to essentially print the fuel.

According to theories of gasodynamics as well as heat transfer from the turbulent gas flow to the burning surface of propellant along a permeable wall, this paper has derived explicit expression for predicting the burning rate of solid propellant with crossflow.

The successful deployment and operation of the Japanese IKAROS and NASA's NanoSail-D solar sails have demonstrated a key method for getting around in space, without having to use any propellant.

Ammonium nitrate (an) propellant used in missile's gas generator is studied for making it having a low burning temperature, clear gas and a larger adjusting rage of burning rate.

This paper describes the charge configuration of a typical cartridge, and the type, shape, charge weight and charge density of the propellant with which a typical cartridge is charged.
