Over the past years, solid rocket motors (SRMs) proved to be a reliable and cost-effective propulsion system for a wide range of rocket-based applications starting from small tactical weapons up to current large space boosters. Many designers and

Hybrid propulsion generally combines a liquid oxidizer with a solid fuel. Compared to solid or bi-liquid engines, this type of propulsion offers advantages in terms of cost and flexibility. For several years, ONERA has been providing expertise in this area, both in experimental and numerical simulations.

A solid rocket motor is a rocket motor that uses a solid mixture of chemicals as its propellant. Nozzle is the part of motor responsible for thrust generation and experiences high amount of temperature and pressure changes. Both propellant and nozzle are crucial for design and construction of rocket motor.

Ammonium dinitramide, or ADN (NH N(NO ) ), is a new and promising oxidizer with high impulse and high burning rate. It is a potential replacement for ammonium perchlorate (NH ClO or AP). Since ADN does not contain chlorine, a composite rocket propellant containing ADN and a polymer binder will produce minimal smoke, and will be more environmentally friendly compared to propellants based on AP.

. INTRODUCTION. Solid Propellant Description. A solid propellant is a complex and stable mixture of oxidizing and reducing ingredients which, when ignited, burns in a controlled manner to form predominantly very hot, low-molecular-weight gases.

Advances in Green Cryogenic Solid Propellant Propulsion. The combustion of hydrocarbons with hydrogen peroxide or oxygen based oxidizers is known as the best possible realization of green bipropellants in the realm of conventional propellants. By the nature of these constituents, corresponding rocket motors are either hybrids or bi-liquids.

//&#;&#;The propellant of SRM is stored in solid form, in which solid fuels and solid oxidizers are held together by a solid binder, forming the so-called composite propellant [ ]. Although SRMs are relatively simple in principle, their modern types are complex systems that must incorporate several technical disciplines and teams to meet stringent mission requirements and design criteria.

Current solid rocket propellant formulations still employ traditional ingredients utilized since the s, such as hydroxyl terminated polybutadiene (HTPB). Recent advances in energetic polymer see many binders capable of providing higher specic impulse and burn rates over HTPB. As

Chemical rockets. The standard means of propulsion for spacecraft uses chemical rockets. There are two main types: solid-fueled (such as the solid rocket boosters on the Space Shuttle), and liquid-fueled (such as the Saturn V). In both cases, a chemical reaction is employed to produce a very hot, highly pressurized gas inside a combustion chamber.

The other type of solid propellant is the composite. Here, separate fuel and oxidized chemicals are used, intimately mixed in the solid grain. The oxidizer is usually ammonium nitrate, potassium chlorate, or ammonium chlorate, and often comprises as much as four-fifths or more of the whole propellant mix.
