Indian Navy buys US electromagnetic catapult

Chairman of the US-India Defense Cooperation, US Deputy Secretary of Defense Frank Kendall stated that the US government approved the sale of India's electromagnetic catapult (Electromagnetic Aircraft Launch System - EMALS), developed by General Atomics, as well as other key military technologies.

“I look with optimism at the cooperation with India to create an aircraft carrier. They (Indians) want to buy an electromagnetic catapult, and I don’t see any obstacles in it, ”he said. "Military Parity".

Indian authorities are going to purchase military technology from the USA to improve the efficiency of their prospective aircraft carriers.

In addition, General Atomics offered a Brazilian Navy catapult.

The export of this system will reduce the cost of installing it on the newest aircraft carrier Gerald R. Ford, which is being built for the US Navy at the shipyard of Huntington Ingalls Industries Inc. The use of an electromagnetic catapult allows you to accelerate the launch of aircraft from an aircraft carrier, providing less fatigue effect on its deck.

It is planned that in the coming months, the parties will hold a joint meeting on this program with the participation of EMALS Executive Director Rear Admiral Thomas Moore and his Indian colleague Surendra Adjuy.

America and India have no contentious interests. And America is betting on India in the fight against China. By the way, how do we know that in our technology there are no embedded switches in case of a conflict with us. India has long been looking for other suppliers of weapons that would not depend on one country, in this case, Russia. Which is very correct both for the country's defense.

[Basarev]

And yet, despite all the catapults, along with the increase in the combat load and, accordingly, the mass of combat aircraft, the deck of the nose begins to be sorely lacking for either take-off or landing. It is much more convenient to build a hydro-air transport and a crane to hang flying boats overboard to take off and land on an endless expanse of water. As for the aircraft themselves, there must be an aerodynamic quality primacy in their development and construction. Everything else is secondary.

In PopMech, there are no calculations or solutions to the problem, only the "emotion" of throwing cars. Here is the 2012 information on EMALS electromagnetic catapult technology

Until February 2011, 3 tests were carried out under a load of 600 to 4 kg, and in the summer, test launches of the F-536 Hornet carrier-based multi-role fighter, the E-45 Hawkeye carrier-based AWACS aircraft and the C carrier-based military transport aircraft were carried out. -359 "Greyhound".
In order to catapult the aircraft from the deck of an aircraft carrier, an EMK linear electric motor with a capacity of 100 liters. with. converts 000 MW of continuously supplied power to 1,35 MW of pulsed power (60 s). The generated current on the last 2 m of the shuttle EMC stops it without the help of a hydraulic brake and returns to the starting position. The energy storage system recharges between starts. The EMC also provides aircraft landing, while only the polarity changes.
The main advantages of EMC in comparison with a steam catapult are low weight and size characteristics and high efficiency. Comparative characteristics of the electromagnetic and steam catapults are given in table. 1. In addition, the EMC has a higher reliability, short preparation time for work and a high degree of automation, which leads to an increase in the number of sorties by 25%.

[aleks 62]

.... All this is from the category of blah-blah-blah ..... For your information 60MW is 81 thousand. l / s ..... Let me remind you - the nuclear icebreaker "Lenin" -45 thousand l / s ...... And the pulse power (60 MW) must be stored somewhere else, that is, some kind of storage is required .. ..The article in the magazine is popular (for the people), that would be clear to the same people .....

The amerovskoy picture says - flywheel. Here's some more info from amers: "In EMALS, the energy from the ship's power supply system (up to 484 MJ) is stored kinetically on four disks of the generator rotors, and then this energy is released in 2-3 seconds. Each rotor can store 121 MJ at 6400 rpm, and can be recharged within 45 seconds of launch, faster than a steam catapult. " And in the amerovskoy picture, motor generators with flywheels do not look large, although only 2 are drawn, but they write that 4.

Duck, it's the Americans vparivayut Indians civilian picture. They are the Americans, and they plan the sizes and catapults and power plants. According to Nimits, the power of the power plant is reported at 191 MW - somewhere else it is placed there. And at Gerald Ford, they - the Americans - plan to reach 650 - 680 MW. So tell me - they lie, do not lie the Yankees?

Quote: aleks 62

Not from him. Just a characteristic of the effectiveness of the system (device, machine) in relation to the conversion or transmission of energy. I suppose - this is the data indicated specifically for catapults, and not in general. I agree completely on a linear electric motor - m. and 97%. And here, according to the EMC, the transformation Source - Flywheel - Generator - Linear ED is wedged in. But in fact, between the generator and the ED of course there will also be a frequency converter. And the power and speed transmitted by the catapult will depend on the parameters of the inverter and the configuration of the linear ED. And the generators will work quite uniformly for themselves.

Interestingly, but the steam in the cylinders of the catapult is taken from the primary loop of the reactor? Own the scheme - share it, I think many will be interested.
Amkos, on the other hand, are developing EMCs having really the richest experience in operating steam engines. This is hardly an accident. Here is a quote:
Americans have been using steam catapults for 45 years and believe that, along with many advantages, these catapults have a number of significant disadvantages:
1. The weight of steam catapults is very large. Each catapult with accessories weighs 2800 tons. Due to the fact that all four catapults on the aircraft carrier are located closer to the upper deck, they significantly reduce the overall stability of the ship.
2. The consumption of a huge amount of fresh water (especially for non-nuclear aircraft carriers) places a heavy burden on the desalination system of the aircraft carrier. For example, in one flight shift, one catapult consumes 80 tons of fresh water.
3. Very difficult maintenance and repair of steam catapults. The great difficulty is the alignment of individual sections of the working cylinders.
4. Steam escaping from the slot during the working stroke impairs visibility on the upper deck and reduces the thrust of aircraft engines.
5. There is a great danger of fires in places of strong heating.
6. Many parts subject to corrosion.
7. Steam catapults occupy a lot of space on the ship.
The catapult has many auxiliary systems:
- steam receivers;
- air conditioners on the gallery deck;
- drainage system for condensate;
- preheating of working cylinders;
- additional desalination plants, etc.
One catapult (without remote controls) occupies a volume of 2265 m 3.
Here are some more arguments for refusing steam catapults:
Modern steam catapults, in order to launch one aircraft, do the work of 70 million feet / pounds (equal to the work of raising one pound per foot). This limits the maximum mass of the ejected aircraft to approximately 70 pounds (000 kg). In addition to this, the momentum of the force applied to the catapult increases at low load, which makes it difficult to launch lighter types of aircraft. In fact, steam catapults are not adapted to launch modern UAVs.
Due to the relatively wider range of variation of the force applied to the ejected aircraft, during one launch cycle, the aircraft glider experiences significant undesirable loads. Such loads reduce the fatigue life (time to fatigue failure) of manned aircraft and require significant reinforcement of the design of the UAV glider.

[Rus2012]

Efficiency of a system with an electrocatapult = 70%, this means 30% of energy in the form of electric pulses will go on the air!
Great!
Even if they remove 2/3 with filters, screens, all the same 10% will go into space, i.e. 12,2 megaJ! Not a frail source of Fourier harmonics! From afar it will "shine" !!

Americans want to reduce costs by selling including technologies

Here is from the 2013 article "Battle for India: US electromagnetic catapults must be opposed by ours" by Alexander Gorbenko:
"The United States is now the only country to openly exhibit its operational ground test facility, which is to become the ship's Electromagnetic Aircraft Launch System (EMALS). It is located at NASC's test facility in Lakehurst, NJ. Last successful launch from the stand took place on November 18, 2011. However, the fine-tuning of this system goes with catastrophic delays and requires additional financial and intellectual injections (the United States is experiencing a serious shortage of qualified scientific personnel) .Since 2008, expenses on EMALS have grown by 133,7%. on this, as of March 2013, the program was behind schedule by more than two years.And each of 2-3 test cycles ended in unsuccessful results.It is already clear that even if the general ship systems of "Ford" will not require another redesign and it will ready by 2016 - then it will go to sea trials without catapults.
This is one of the main reasons for the American proposal. It is very difficult for Americans to maintain the status of a military and technological leader on their own. The usual geopolitical partners / satellites are either not capable of much, or experience similar financial and intellectual difficulties. And India has a good financial base and an actively expanding scientific potential. It is strengthening its defenses and needs modern weapons. So why not use all of this to your advantage? "

[gjv]

Quote: ma_shlomha

then the next step is to develop an electromagnetic aerofinisher

The same factory is developing, but not electromagnetic with movable fittings. Apparently they consider such a design too cumbersome. They have a development called AAG (Advanced Arresting Gear). Here is the information (2012) on the technology:

The electromechanical system of the new generation includes a hydraulic brake (water turbine), a mechanical brake and an electric motor-generator. The speed of the aircraft (through the cable device) when landing on the deck of an AVMA (this is a projected "Gerald Ford") is damped mainly by a mechanical and hydraulic brake. The electric motor-generator with the help of an automatic monitoring and control system provides optimal smooth regulation of the retarding force braking the aircraft (taking into account its mass characteristics). The electric motor-generator has extremely low inertia and at the same time high torque, which is achieved by the peculiarities of its design: the rotor is a magnetically conductive cylinder enclosed between two concentrically located inner and outer stators.

At the right time, this device will refuse to push the plane off the deck if the operation of the Indian Navy is not in the interests of the mattresses. Even a fortuneteller does not need to go.
