Solid Fuel Ducted Ramjet
Solid Fuel Ducted Ramjet (SFDR) is a missile Propulsion, propulsion system currently being developed by the Defence Research and Development Organisation of India. The project aims to develop critical technologies required in the propulsion systems of future Indian Beyond-visual-range missile, long range air-to-air missiles. Description The Solid Fuel Ducted Ramjet (SFDR) is a missile Propulsion, propulsion system that includes a thrust modulated Air-augmented rocket, ducted rocket with a reduced smoke nozzle-less missile Booster (rocketry), booster. The thrust modulation in the system is achieved using a hot gas flow controller. The system utilises a Solid-propellant rocket, solid fuelled air-breathing ramjet engine. It is an extremely long-range missile with a projected range of 350 km. As per International Institute for Strategic Studies (IISS), this kind of propulsion system drastically enhances the range with higher average speed. The missiles which use such system are al ...

Defence Research And Development Laboratory
Defence Research and Development Laboratory (DRDL) is an Indian missile development laboratory, part of the Defence Research and Development Organization (DRDO). Their charter is centered on the design, development, and flight evaluation of various types of missile systems for the Indian armed forces. History In 1958, the Indian government constituted a team of engineers, mostly from the Indian Ordnance Factories Service - called the Special Weapons Development Team - to research guided missile weapons development. It was founded by S. P. Chakravarti, the father of Electronics and Telecommunication engineering in India, who also founded the DLRL and the Electronics and Radar Development Establishment (LRDE). This team was later expanded into DRDL, a full-fledged laboratory, in June 1961, at the campus of Defence Science Centre, Delhi. It later shifted to Hyderabad after the state government granted them the former Nizam's army barracks. This was the genesis of the Defence ...

Astra (missile)
Astra (Sanskrit: "Weapon") is an Indian family of all weather beyond-visual-range air-to-air missile (BVRAAM) developed by the Defence Research and Development Organisation (DRDO) for the Indian Air Force and the Indian Navy. Multiple variants of this missile has been developed with engagement range varying from to . Astra Mk-1 has been integrated with the Sukhoi Su-30MKI fleet. The missile will be integrated with the entire fighter fleet except the Dassault Mirage 2000 of the Indian Air Force as well as the Dassault Rafale fleet of the Navy. In 2024, the missile was cleared for full production. Description Astra Mark-1 Astra Mk-1 is long with a diameter of and weighs . It uses mid-course Inertial navigation system, inertial guidance driven by fibre-optic gyroscope with terminal guidance through active radar homing. It is capable of receiving course corrections through a secure data link. The missile's active radar seeker, with a homing range of , was designed by Russi ...

Specific Impulse
Specific impulse (usually abbreviated ) is a measure of how efficiently a reaction mass engine, such as a rocket engine, rocket using propellant or a jet engine using fuel, generates thrust. In general, this is a ratio of the ''Impulse (physics), impulse'', i.e. change in momentum, ''per mass'' of propellant. This is equivalent to "thrust per massflow". The resulting unit is equivalent to velocity. If the engine expels mass at a constant exhaust velocity v_e then the thrust will be \mathbf = v_e \frac . If we integrate over time to get the total change in momentum, and then divide by the mass, we see that the specific impulse is equal to the exhaust velocity v_e . In practice, the specific impulse is usually lower than the actual physical exhaust velocity inefficiencies in the rocket, and thus corresponds to an "effective" exhaust velocity. That is, the specific impulse I_ in units of velocity *is defined by* : \mathbf = I_ \frac , where \mathbf is the average thrust. ...

Mach Number
The Mach number (M or Ma), often only Mach, (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach. \mathrm = \frac, where: * is the local Mach number, * is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and * is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
