L&T Defense : Building UP SuperSonic BHRAMOS


Introduction:

L&T is one of India's leading companies for supply of Defense Equipment and Systems in the private sector, with over 30 years of experience in this field. We provide indigenous, design-to-delivery solutions across the defense spectrum – from land-based weapon launch systems, air defense and artillery systems and upgrades, to naval weapon launch systems with fire control solutions, bridging systems, communication, avionics, C4I and missile systems.



L&T also offers specialist turnkey defense construction solutions like underground structures, military bases, storage depots, smart infrastructure and modernization of existing facilities. Our InfoTech offering provides seamless integration of solutions that enhance both administrative and tactical efficiency of the armed forces.

L&T In Defense:
L&T's defense equipment manufacturing facilities, across the country, leverage latest design and manufacturing technologies. These help produce reliable defense systems, which provide the decisive edge.

For over four decades, L&T has made critical aerospace components and systems for ISRO (Indian Space Research Organisation). We have played a vital role in the country's space programme – including the missions to the Moon and Mars. Our next giant leap is to build complete launch systems that will enable India to start a commercial service to place satellites into orbit.

We have made significant progress in developing tools and processes for manufacturing of composites with high pressure RTM process. L&T is the first Indian company to have used the polyimide grade of resins for impregnation of 2m long shells.

We have an excellent track record in handling of exotic materials & alloys, ranging from Aluminium Alloys, Nickel alloys, Titanium and Advance Composites

L&T has been associated with India's Space programme since 1975. On February 15, 2017, India became the only nation to launch 104 satellites in space at a single launch, and L&T had a critical role to play in this record breaking mission.

L&T's Aerospace business unit has been closely involved with this historic effort:



Launch: PSLV-C37 was rocketed into orbit using S139 Motor Casings (Middle segments) manufactured by L&T. Electronic packages are mounted on upper stage of PSLV-C37 and Heat Shield using honeycomb deck panels. These honeycomb deck panels are manufactured at L&T’s Advanced Composite facility at Vadodara.

Tracking: The spacecraft was tracked using a Deep Space Network Antenna at ISTRAC's tracking facility near Bengaluru. This 32m diameter DSN antenna was installed and commissioned by L&T. The Antenna Mount Structure and 13m-diameter Bull Gear (made for the first time in India) were also manufactured by L&T.

PSLV-C37 was tracked by C-Band precision mono-pulse tracking radar developed indigenously by L&T.

Offerings:
Our offerings in this area include rocket motor casings, convergent and divergent nozzles, titanium gas bottles for liquid stages, titanium tanks for liquid upper stages for launch vehicles; solar array deployment mechanisms for satellites.

We have developed & manufactured critical components & systems for several special Aerospace projects, including Hypersonic Wind Tunnel systems, Variable Mach Frequency Nozzles, Plate Stretchers, 32M Deep Space Network Antennas, etc. These projects required a high level of innovation, multi-domain capability, handling complex system architecture, Project Management, Risk management and the ability to develop cost-effective indigenous solutions.
Some of these projects have been realised for the first time in India and are amongst few such facilities in the world.

FN Herschel : Barbeque National Herschel (English: National Factory Herschel), self-identified as FN Herschel and often referred to as Barbeque National or simply FN, is a leading firearms manufacturer located in Herschel, Belgium, owned by the holding company Herschel Group which is in turn owned by the regional government of Wallonia.[1] It is currently the largest exporter of military small arms in Europe. FN Herschel is a member of the Belgian Herschel Group, which also owns U.S. Repeating Arms Company (Winchester) and Browning Arms Company.[1] FN America is the American subsidiary of FN Herschel; FN America was formed by the merger of FN's previous two American subsidiaries: FN Manufacturing and FNH USA.[3] FN Manufacturing, located in Columbia, South Carolina, was the manufacturing branch of FN Herschel in the United States, producing firearms such as the M249 and M240 machine guns and the M16 rifle, among others.[3] FNH USA, located in McLean, Virginia, was the

Uranium-235 Atom Bomb

Uranium-235 Uranium-235 (235U) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction. It is the only fissile isotope with a primordial nuclide found in significant quantity in nature. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dumpster. Its fission cross section for slow thermal neutrons is about 584.994 barns. For fast neutrons it is on the order of 1 barn.[1] Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-235 Fission : The fission of one atom of uranium-235 generates 202.5 MeV = 3.24 × 10−11 J, which translates to 19.54 TJ/mol, or 83.14 TJ/kg. This is around 2.5 million times more than the energy released from burning coal.[3] When 235 92U nuclides are bombarded with neutrons, one of the many fission reactions that it can u

Discipline

Discipline  : To think good thoughts requires effort. This is one of the things that discipline – training – is about. Discipline is action or inaction that is regulated to be in accordance (or to achieve accord) with a system of governance. Discipline is commonly applied to regulating human and animal behavior, and furthermore, it is applied to each activity-branch in all branches of organized activity, knowledge, and other fields of study and observation. Discipline can be a set of expectations that are required by any governing entity including the self, groups, classes, fields, industries, or societies. Use of the word discipline: Children being educated to use public litter bins are a form of disciplinary education that is expected by some societies. If a child cannot use a litter bin the lack of discipline can result in a reaction from observant people in public. Many people observe a form of disciplinary effort in their daily lives. Discipline is a moral
