چکیده

The nanosized powders have gained attention to produce materials exhibiting novel properties and for developing advanced technologies as well. Nanosized exhibit substantially favourable qualities such improved catalytic activity, augmentation in reactivity, reduction melting temperature. Several researchers pointed out the influence of ultrafine aluminium (∼100 nm) nanoaluminium (<100 on burning rates composite solid propellants comprising AP oxidizer. inclusion augments rate by means particle’s ignition through leading edge flames (LEFs) anchoring above interfaces coarse AP/binder binder/fine matrix sandwiches containing 15% loading binder lamina increment about 20–30%. It was noticed that with is around 1.6–2 times respect propellant compositions without various pressure ranges also different micron-sized particles composition. addition nano-Al washes plateaus trends are perceived from non-Al microaluminized propellants; however, nanoaluminized demonstrate low-pressure exponents at higher level. contribution catalysts towards reduced apparent only catalysts. near-surface diffusion-limited particle combustion contribute heat propellant-regressing surface dominates rate. Quench-collected residues display notable agglomeration, although a minor percentage agglomerates 1–3 µm range; these within 5 size. Percentage elongation initial modulus decreased when replaced

Analytical Solution for Pressure-Coupled Combustion Response Functions of Composite Solid Propellants

This paper extends the classical analytical solution for small perturbation analysis of the pressure-coupled response of a homogeneous propellant to any two-component composite propellant. The solution obtained is general and can be used with any particular model for propellant combustion. As an example, the Cohen and Strand ammoniumperchlorate propellantmodel for a single ammoniumperchlorate p...

Ammonium Nitrate as an Oxidizer in Solid Composite Propellants

Despite the fact that ammonium nitrate (AN) has the highest hydrogen content and fairly high oxygen balance (compared to other oxidizers), its extremely low formation enthalpy and relatively low density makes it one of the worst power oxidizers in solid composite propellants (SCP). Nevertheless, AN has certain advantages ¡ the combustion of the compositions containing AN is virtually safe, its ...

Low Acid Producing Solid Propellants

The potential environmental effects of the exhaust products of conventional rocket propellants have been assessed by various groups. Areas of concern have included stratospheric ozone, acid rain, toxicity, air quality and global warming. Some of the studies which have been performed on this subject have concluded that while the impacts of rocket use are extremely small, there are propellant dev...
