Ignition and combustion characteristics of metallized propellants. Experimental and analytical investigations focusing on secondary atomization and ignition characteristics of aluminum/liquid hydrocarbon slurry propellants were conducted.
Experimental efforts included the application of a laser-based, two-color, forward-scatter technique Author: Stephen R. Turns and D. Mueller. Research designed to develop detailed knowledge of the secondary atomization and ignition characteristics of aluminum slurry propellants was started.
These processes are studied because they are the controlling factors limiting the combustion Ignition and combustion characteristics of metallized propellants book of aluminum slurry propellants in Author: M. Scott, S. Turns and D. Mueller. propellants which provide an optimum combination, or an intelligent trade-off, of rheological and combustion characteristics.
Moreover, understanding and being able to predict ignition times for small droplets will provide guidelines for feasibility and developmental studies of metallized propellant engine systems prior to the. SUMMARY Shakedownandcalibrationof theexperimentalapparatusdesigned to study secondary atomization and ignition characteristics of aluminum slurry propellants was begun and nears comp!etion.
The burner was tested over an array of equivalence ratios and oxygen mass fractions to determine the permissible range of operating conditions. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA In spite of long history of the study of the laser ignition (LI) of metalized solid propellants (MSP) there is no commonly accepted opinion on mechanism of the laser initiation.
It is due to wide variety of energetic materials and sources of laser irradiation. Meanwhile, the examined characteristics Author: Igor G.
Assovskiy. Dec 24, · The solid-state ignition of a metallized composite propellant (ammonium perchlorate + 14% butyl rubber +5% aluminum powder + 6% plasticizer) under local heating by several sources of limited power capacity (dimensions of the hot particle x p = 4 mm and y p = 2 mm) was studied by mathematical runrevlive.com by: 1.
The combustion of metallic fuels is an important consideration for composite propellants. The thermal reactivity of the metal has a significant influence on its ignition and combustion characteristics. Fig. 4 shows the TG, DTG and DSC curves for the Al and Al-FCOS powders.
There are two valleys, at °C and °C, in the DTG curves for the Al-FCOS composite particles, but none for the virgin Al runrevlive.com by: 2. Ignition. is the inside story of the Cold War era search for a rocket propellant that could be trusted to take man into space.
A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio/5.
Abstract Though metals and metalloids have been widely considered as reactive fuels, the ability to tune their ignition and combustion characteristics remains challenging. One means to accomplish this may be through low-level inclusion of secondary materials into the metallized fuel.
velopment of liquid rocket propellants: the who, and when, and where and how and why of their development. The story of solid propellants will have to be told by somebody else. This is, in many ways, an auspicious moment for such a book.

National Aeronautics and Space Administration.]. Small-scale ballistic evaluation motor is widely accepted to measure combustion characteristics of solid propellants during static firing tests. The burning rate and the specific impulse are the main parameters which need to be precisely optimized and evaluated during combustion process to meet specific propulsion requirements (booster, sustainer, or dual thrust rocket motor).Cited by: 2.
A mathematical model for the ignition of a single encapsulated particle is proposed. Calculations show a decrease in the ignition time of an aluminum particle with a ﬂuorine-containing coating.
