Dividing ANY unit into 10's, 100's and 1000's is a lot easier, more accurate and logical than dividing it by the archaic fractions of 8's, 16's, 32's ya know. Imperial Units were devised back in the days of British colonial merchant times based on a person's hand, foot, or step length which was fine back then, but may not be the most appropriate measurement nowadays, though they can coexists just fine till it gets phased out after a few more generations. ;)

Nice simplified description of cat launching ! Thanks!

[@Wh0isTh3D0ct0r]

3:09 Not exactly. The reason why the deck is angled is not because of planes and personnel at the front of the ship. It's so that if a plane misses and crashes into the ocean, the ship doesn't run into the plane. This aids in the safety and recovery of the aviators. Planes and personnel being toward the bow of the ship is just a byproduct of the angled deck.

[@tonymanero5544]

Trump, and his friends like Mannafort Flynn others are on the payroll of Russia, Saudi Arabia and some adversaries. But China got some good reverse engineering from an Australian carrier that was scrapped in China when Australia didn’t remove some valuable machinery. And other American corporations hand over technology because they think partnering with Chinese companies would increase revenues; 10 years later China learned well and can do it themselves. Walmart in the 1980’s bought a lot of China made products that put American companies out of business and closed American factories. But the Walton family became billionaires doing that and other capitalists soon followed. The price of HDTV are still coming down thanks to China but hotels and car rentals by American companies are going up.

[@boscojacko2485]

I did three cruises. First one...I met half way their cruise in North China Sea...First full tour....our carrier went into dry dock for modernization and retrofit after last Vietnam duty. Every ship in their action zone or in training kicks ass every day. Fast forward to this excellent video....No planes are seen on deck....this would mean that this particular nuclear powered aircraft carrier is out doing CQ's...or Carrier Qualification" and their entire purpose is to crank it wide open in blue water, make it lean into turns, stress it to it's limits because there is no aircraft onboard or fuel to compensate for. Ships Crews inside (black shoe and Airedales) get a real treat of full speed thrust to max speed internal vibration, all unusual noises, and awesome tilts to port or starboard (left or right) turn exercises. Plenty of GQs (general quarters) exercises for training. If something is going to break or fail ...this is the place you want to fail...not overseas or in the middle of nowhere. Air wing personnel are all waiting for their individual squadrons to land and the practice party is over for now.....then off to the mission duty station and ports of call in the real world. Our tours of duty (cruise) was about 6 months. Squadrons get to go home to their home base with their planes and support crews. Ships company remained onboard carrier at their home ports...almost always not in the same city.

[@chachi1rg]

Your aircraft recover portion only covered the damper systems and not the arresting gear engine. It would be nice to see that system in detail.

[@jccalhoun4972]

Wire through pulleys pushes the hydraulic fluid through an orifice. There’s a valve on that orifice that closes as the cable pays out. It’s a feed forward/feed back system based on the programmed weight of the aircraft, (36,000 for a Fa-18C for example) and how fast that cable is pulled. Once that valve is closed, cable payout stops, and so does the airplane. Regardless of the weight and speed of the aircraft, the cable pays out the same amount if everything works as advertised.

[@maxhagenauer24]

You said this is twice the linier Gs of the fastest roller coaster but its not about speed, its about the acceleration. Formula Rossa is the fastest coaster but defiantly not the fastest accelerating, the fasted accelerating coaster actually gets pretty close to this force, Dodonpa is a compressed air launch coaster in Japan that launched from 0 - 112 mph in 1.56 seconds.

It's interesting that you would mention Formula Rossa, since there are many similarities between aircraft launches and rollercoaster launches. For example, you mentioned how the system used to be hydraulic. Intamin Accelerators, such as Formula Rossa, also use hydraulic launches. You also mentioned how they were working on electromagnetic launch systems. Some rollercoasters also utilize electromagnetic launches. Rides such as Flight of Fear at Kings Island/Kings Dominion and Mr. Freeze Reverse Blast use Linear Induction Motors (LIMs) to lauch coasters. On the other hand, rides such as Maverick at Cedar Point or Full Throttle at Six Flags Magic Mountain use Linear Synchronus Motors (LSMs).

Good basic explanation of Catapult systems. How about getting to the real dynamics of how catapult operations really work. Starting with the hydraulic / pneumatic systems below decks? Could you provide a “in depth” diagram explanation of Steam & Hydraulic flow prior to launch? And how exactly the Rotary Retraction Engine works in conjunction with the “Grab” assembly? Also curious how the Water Brakes stop the pistons so quickly after launching so fast. I think that would be helpful info the rest of the population would like to know.

[@carmelpule6954]

As far as I know, though we call the aircraft-catapult a "steam catapult", it is better described as a "superheated water catapult" If the steam released in the two zipped cylinders was dry steam, the pressure would drop off rather quickly and the push on the two pistons pulling the aircraft would drop substantially and so it is wet steam that is used with a lot of superheated water in it. To construct an objective launching function as a constant pressure with a launching catapult, one needs to include, four wet steam accumulator parameters: namely, the accumulator pressure, superheated water level, accumulator volume, and accumulator radius to get the evaporation rate, right. If it was dry steam alone, the pressure would drop as soon as the aircraft starts to move, but with superheated water in the accumulator tanks, the pressure is kept constant for as long as there is a drop of superheated water in the accumulator tank. It is after all the superheated water evaporates that the pressure in the two launching tubes/pistons starts dropping but by this time the aircraft is flying and the piston is arrested by a hydraulic water buffer. It is very important to understand the need for wet steam and the thermodynamics of wet superheated water and the calculation of how much to put in the wet accumulator is of great importance as related to the mass of the aircraft being launched. The wire arresting gear damping and slowing down system is a system of pulleys where the slack in the arresting wire is taken by hydraulic accumulators with high-pressure nitrogen expansion or contracting chambers as is found in a normal hydraulic system where a high motion sudden demand is needed.

[@robertrichard6107]
