Measurement of Combustion Temperature of Solid Propellant by FTIR Spectrometer
نویسندگان
چکیده
The temperature of solid state propellant combustion flame is studied by a Bruker OPAG33 Fourier Transform Infrared Spectrometer (FTIR). The infrared emission spectra of Nitrate Ester Plasticized Polyether Propellant (NEPE) solid propellant are measured with a resolution of 4 cm−1 at a testing distance of 20 m in real time. The temperature of NEPE propellant plume is calculated by using the fine structure emission spectral lines of HC1 gas molecules released in combustion products. The experimental results show that a passive remote sensing FTIR can measure the temperature of solid propellant plume rapidly and non-contactly in real time. It is an effective means for research.

Hydroxyl terminated polybutadiene (HTPB) is the most important and versatile binder in composite solid propellant, But the immiscibility of this polymer with traditional energetic plasticizers is a disadvantage limits its application as a binder for compounding of high energy propellant. In this research, two types of energetic plasticizer, 2-ethylhexyl nitrate (2EHN) and 2-ethyl-2-buthyl-1, 3 ...

An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

Cracking is the breaking of bonds in a part of the propellant polymer due to the existing stresses that change the structure of the propellant polymer and they are classified into two general categories: macrocrack and microcrack. The service life of rocket engines is largely a function of the mechanical properties of the solid rocket propellant, the aging characteristics of the rocket propulsi...

The method of foil embedding is employed in solid propellant motors with end-burning configuration, thereby significantly improving the burning rate of the propellants. These foils provide such amplification by locally augmenting heat feedback from propellant combustion products to unburned solid material, with resultant increase in burning surface area. Burning rate would raise with the incr...
