High Speed Low Drag Bomb
The High Speed Low Drag (HSLD) bomb is a family of new generation short range air-dropped precision-guided munition that is currently being developed by India's Defence Research and Development Organisation (DRDO). This general-purpose bomb is made for the Indian Air Force (IAF) and can be used against the destruction of strategic high value enemy infrastructure from stand-off distances. HSLD is comparable to Mark 80 series of bombs used by United States Air Force (USAF). Between May to June 2017, multiple test were conducted successfully for 450 kg and 500 kg class general purpose bomb (GPB) as well as of precision guided high speed low drag (PGHSLD) munition. Description The Armament Research and Development Establishment (ARDE), Pune is the primary agency that started developing HSLD with the help from other DRDO laboratories to upgrade the conventional free fall unguided ordnance used by the Indian Air force (IAF) fighter pilots while Ordnance Factory Board (OFB ...

Precision-guided Munition
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped. Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced. The advent of precision-guided munitions resulted in the renaming of older, low-technology, bombs as " un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SEPECAT Jaguar
The SEPECAT Jaguar is an Anglo-French jet attack aircraft originally used by the British Royal Air Force and the French Air Force in the close air support and nuclear strike role. It is still in service with the Indian Air Force. Originally conceived in the 1960s as a jet trainer with a light ground attack capability, the requirement for the aircraft soon changed to include supersonic performance, reconnaissance and tactical nuclear strike roles. A carrier-based variant was also planned for French Navy service, but this was cancelled in favour of the cheaper, fully French-built Dassault-Breguet Super Étendard. The aircraft were manufactured by SEPECAT (Société Européenne de Production de l'avion Ecole de Combat et d'Appui Tactique), a joint venture between Breguet and the British Aircraft Corporation, one of the first major joint Anglo-French military aircraft programmes. The Jaguar was exported to India, Oman, Ecuador and Nigeria. The aircraft was used in numerous co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mach Number
Mach number (M or Ma) (; ) 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 Moravian 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). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordnance Factory Board
Ordnance Factory Board (OFB), consisting of the Indian Ordnance Factories, now known as Directorate of Ordnance (Coordination & Services) was an organisation, under the Department of Defence Production (DDP) of Ministry of Defence (MoD), Government of India. The 41 Indian Ordnance Factories have been converted into 7 Defence Public Sector Undertakings (DPSUs). OFB was the 37th-largest defence equipment manufacturer in the world, 2nd-largest in Asia, and the largest in India. OFB was the world's largest government-operated production organisation, and the oldest organisation in India. It had a total workforce of about 80,000. It was often called the "Fourth Arm of Defence", and the "Force Behind the Armed Forces" of India. Its total sales were at () in the year 2020–'21. It was engaged in research, development, production, testing, marketing and logistics of a product range in the areas of air, land and sea systems. OFB consisted of forty-one ordnance factories, nine traini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unguided Bomb
An unguided bomb, also known as a free-fall bomb, gravity bomb, dumb bomb, or iron bomb, is a conventional or nuclear aircraft-delivered bomb that does not contain a guidance system and hence simply follows a ballistic trajectory. This described all aircraft bombs in general service until the latter half of World War II, and the vast majority until the late 1980s. Then, with the dramatically increased use of precision-guided munitions, a retronym was needed to separate "smart bombs" from free-fall bombs. "Dumb bomb" was used for a time, but many military circles felt it sounded too trite, and eventually "gravity bomb" gained popularity. Bomb casings for unguided bombs are typically aerodynamic in shape, often with fins at the tail section, which reduce drag and increase stability after release, both of which serve to improve accuracy and consistency of trajectory. Unguided bombs typically use a contact fuze for detonation upon impact, or some milliseconds after if a penetrati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mark 80
A general-purpose bomb is an air-dropped bomb intended as a compromise between blast damage, penetration, and fragmentation in explosive effect. They are designed to be effective against enemy troops, vehicles, and buildings. Characteristics General-purpose (GP) bombs use a thick-walled metal casing with explosive filler (typically TNT, Composition B, or Tritonal in NATO or United States service) comprising about 30% to 40% of the bomb's total weight. The British term for a bomb of this type is "medium case" or "medium capacity" (MC). The GP bomb is a common weapon of fighter bomber and attack aircraft because it is useful for a variety of tactical applications and relatively cheap. General-purpose bombs are often identified by their weight (e.g., ). In many cases this is strictly a ''nominal weight'' (the counterpart to the ''caliber'' of a firearm), and the actual weight of each individual weapon may vary depending on its retardation, fusing, carriage, and guidance syst ...

Aerial Bomb
An aerial bomb is a type of explosive or incendiary weapon intended to travel through the air on a predictable trajectory. Engineers usually develop such bombs to be dropped from an aircraft. The use of aerial bombs is termed aerial bombing. Bomb types Aerial bombs include a vast range and complexity of designs. These include unguided gravity bombs, guided bombs, bombs hand-tossed from a vehicle, bombs needing a large specially-built delivery-vehicle, bombs integrated with the vehicle itself (such as a glide bomb), instant-detonation bombs, or delay-action bombs. As with other types of explosive weapons, aerial bombs aim to kill and injure people or to destroy materiel through the projection of one or more of blast, fragmentation, radiation or fire outwards from the point of detonation. Early bombs The first bombs delivered to their targets by air were single bombs carried on unmanned hot air balloons, launched by the Austrians against Venice in 1849 during the Firs ...
