Solid Fuel Ducted Ramjet (SFDR) is a missile 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 long range air-to-air missiles. [3]
The Solid Fuel Ducted Ramjet is a missile propulsion system that includes a thrust modulated ducted rocket with a reduced smoke nozzle-less missile booster. [2] The thrust modulation in the system is achieved using a hot gas flow controller. [2] The system utilises a solid fuelled air-breathing ramjet engine. [1] [4] [5] It is an extremely long-range missile with a projected range of 350 km. [6] 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 also able to carry larger payload due to absence of an oxidiser. Unlike solid-propellant rocket, the Ramjet takes up oxygen from the atmosphere during flight. [7] [5] [8]
Officially, the technology is being developed to power future Indian air-to-air missiles. [1] However, the technology can also be applied to surface-to-air missiles. [5]
In its current form, the SFDR-based missile first requires to be boosted into a high-altitude trajectory to simulate aircraft-launch conditions. Subsequently, the nozzle-less booster fires up and guides the missile through its desired trajectory. [1]
The development of the SFDR started in 2013 and envisaged a five-year deadline to begin actual demonstrations. [4] The missile is being developed primarily by the Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI) in Hyderabad. [4] High Energy Material Research Laboratory (HEMRL) developed the nozzle-less booster while the ramjet engine is being developed with Russian assistance. [5] [9] Ground-based testing of the missile started in 2017. [2]
A ramjet is a form of airbreathing jet engine that requires forward motion of the engine to provide air for combustion. Ramjets work most efficiently at supersonic speeds around Mach 3 and can operate up to Mach 6.
Air-augmented rockets use the supersonic exhaust of some kind of rocket engine to further compress air collected by ram effect during flight to use as additional working mass, leading to greater effective thrust for any given amount of fuel than either the rocket or a ramjet alone.
A scramjet is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion, but where as a ramjet decelerates the air to subsonic velocities before combustion using shock cones, a scramjet has no shock cone and slows the airflow using shockwaves produced by its ignition source in place of a shock cone. This allows the scramjet to operate efficiently at extremely high speeds.
The Meteor is a European active radar guided beyond-visual-range air-to-air missile (BVRAAM) developed and manufactured by MBDA. It offers a multi-shot capability, and has the ability to engage highly maneuverable targets such as jet aircraft, and small targets such as UAVs and cruise missiles in a heavy electronic countermeasures (ECM) environment with a range far in excess of 200 kilometres (110 nmi).
The Agni-III is an Indian intermediate-range ballistic missile inducted into service in 2011 as the successor of the Agni-II. It has a range of 3,500 to 5,000 kilometres and can reach targets deep inside neighbouring countries including Pakistan & China.
Prithvi is a tactical surface-to-surface short-range ballistic missile (SRBM) developed by Defence Research and Development Organisation (DRDO) of India under the Integrated Guided Missile Development Program (IGMDP). It is deployed by India's Strategic Forces Command.
The Integrated Guided Missile Development Programme (IGMDP) was an Indian Ministry of Defence programme for the research and development of the comprehensive range of missiles. The programme was managed by the Defence Research and Development Organisation (DRDO) and Ordnance Factories Board in partnership with other Indian government political organisations. The project started in 1982–83 under the leadership of Abdul Kalam who oversaw its ending in 2008 after these strategic missiles were successfully developed.
Akash is a medium-range mobile surface-to-air missile (SAM) system developed by the Defence Research and Development Organisation (DRDO) and produced by Bharat Dynamics Limited (BDL). Surveillance and Fire control radar, tactical control and command center and missile launcher are developed by Bharat Electronics (BEL), Tata Power Strategic Engineering Division and Larsen & Toubro. The Akash missile system can target aircraft up to 45 km (28 mi) away. It has the capability to neutralise aerial targets like fighter jets, cruise missiles and air-to-surface missiles. It is in operational service with the Indian Army and the Indian Air Force.
Astra is an Indian family of all weather beyond-visual-range air-to-air missile, developed by the Defence Research and Development Organisation. Different missiles of this family are capable of engaging targets at varying distances of 500 m (0.31 mi) up to 340 km (210 mi). Astra Mk-1 has been integrated with Indian Air Force's Sukhoi Su-30MKI and will be integrated with Dassault Mirage 2000, HAL Tejas and Mikoyan MiG-29 in the future. Limited series production of Astra Mk-1 missiles began in 2017.
Scramjet programs refers to research and testing programs for the development of supersonic combustion ramjets, known as scramjets. This list provides a short overview of national and international collaborations, and civilian and military programs. The USA, Russia, India, and China (2014), have succeeded at developing scramjet technologies.
Nirbhay is a long range, all-weather, subsonic Cruise Missile designed and developed in India by the Aeronautical Development Establishment (ADE) which is under Defence Research and Development Organisation (DRDO). The missile can be Launched from Multiple Platforms and is capable of carrying conventional and nuclear warheads. It is currently deployed in limited numbers in Line of Actual Control (LAC) during standoff with China.
The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect India from ballistic missile attacks. It was launched in 2000 after Kargil War by the Atal Bihari Vajpayee government. Testing was carried out and continuing as of 2006, and the system was expected to be operational four years from then according to the head of the country's missiles development programme, Vijay Kumar Saraswat.
The HSTDV is an unmanned scramjet demonstration aircraft for hypersonic flight. It is being developed as a carrier vehicle for hypersonic and long-range cruise missiles, and will have multiple civilian applications including the launching of small satellites at low cost. The HSTDV program is being run by the Defence Research and Development Organisation (DRDO).
The Creative Research On Weapons or Crow program was an experimental missile project developed by the United States Navy's Naval Air Missile Test Center during the late 1950s. Intended to evaluate the solid-fueled integral rocket/ramjet (SFIRR) method of propulsion as well as solid-fueled ramjet engines, flight tests were conducted during the early 1960s with mixed success.
Barak 8, also known as LR-SAM or MR-SAM, is an Indo-Israeli jointly developed surface-to-air missile (SAM) system, designed to defend against any type of airborne threat including aircraft, helicopters, anti-ship missiles, and UAVs as well as ballistic missiles, cruise missiles and combat jets. Both maritime and land-based variants of the system exist.
India has studied, produced and used various strategic and tactical missile systems since its independence. Decades long projects have realised development of all types of missile systems including ballistic, cruise, anti-ship, air-defence, air-to-air and anti-missile systems. India is one of seven countries in the world with intercontinental ballistic missiles (ICBMs) and one of four countries with anti-ballistic missile systems. Since 2016, India has been a member of Missile Technology Control Regime (MTCR).
