"Should we get on the Rockets to boost?" Just then, a person said.
If the power is not enough, it can only be a crooked way. Of course, rocket boost is not a crooked way. In the development of carrier-based aircraft, there is a market for rocket boost.
The plane takes off directly from the aircraft carrier and faces the problem of insufficient thrust. This power can be solved by external means. In addition to the catapult to provide power, the use of rockets is also an idea, as long as additional power is added. .
In fact, it is not just the carrier-based aircraft, but also rocket boosters. In fact, there is an emergency thinking.
For example, in the mid-1950s, NATO feared that a Soviet nuclear bomb attack might destroy Allied airfields and aircraft parked on the ground, rendering NATO unable to retaliate.
Therefore, they decided to evacuate the fighter jets into a bunker far away from the airport and with nuclear protection capabilities. In this way, they could indeed escape the nuclear strike, but after the nuclear strike, they had no runway.
Then, in order to achieve takeoff, they mounted these aircraft on a special support with rocket-assisted takeoff, so that the interceptor could take off in an emergency and intercept. The concept is zero-range launch.
For this experiment, the Rocket Propulsion Division of North American Aviation has developed a solid rocket motor that can be installed on the bottom of the f100d rear fuselage. The engine can generate 58,970.44 kilograms of thrust for four seconds, enough to accelerate the f100d from 0 to 482.70 kilometers per hour in 4 seconds. The rocket engine fell off after running out of fuel, and the f100 continued to climb with its own power.
This time the experiment was a success, but in the end it didn't stop. There was no service.
Not only fighter jets can be used, but in later generations, there will even be experiments conducted by transport aircraft. For special actions, the Americans decided to install rocket boosters on the fuselage of the c130. Such a transport aircraft abruptly realized a short range. The ability to take off and land.
It is simply impossible to complete the task of taking off and landing in a space the size of a football field.
As a result, the initial experiment was successful until the last time, because the rocket was started too early, which eventually failed, and it was not put into actual use.
After talking for a long time, in short, this thing is not so easy to use, and emergency is not good, let alone a large number of use on aircraft carriers.
Don’t talk about other issues, even if the reliability is sufficiently guaranteed, just talk about the rocket thruster, how to do it
If it can be reused, where is it thrown out every time? Is it on the deck or in the sea? Is it necessary to dispatch a helicopter to fish every time
If it is a one-off, how many booster rockets do you need to carry as a spare when you go to sea
This problem alone is maddening enough, and as long as one of them is of unqualified quality, it may cause a major disaster. The U.S. Navy also has a lesson. Just a rocket accidentally ignited on deck. Almost burned the entire aircraft carrier.
So, after hearing someone’s suggestion, Nathan immediately shook his head: “No, absolutely not, it’s not suitable to boost the Rockets.”
If you want to be suitable, why do you have a catapult? Just use boost rockets. Now, Nathan immediately rejected the idea of boosting rockets.
"Or, let's make a slot on the deck and install a catapult?" In short, the thrust is not enough, and we need to find a way. Can we install a simple catapult? There is no need to be tens of meters long, even 20 meters, it is enough to provide enough extra power for the aircraft.
It's just a few tons of mounted thrust.
Catapult
Do not make jokes!
If there was a catapult when it was originally designed, then the equipment is still okay. If there was no catapult when it was designed, and now the catapult is modified, the amount of engineering will definitely make the Navy crazy.
It's not just as simple as opening a slot. Where are the pressure tanks attached to the catapult? Does the power system support? Yes, you have an aircraft carrier powered by gas turbines. Where can you get steam? Do you need to add another boiler? How stupid is that
"No, the amount of engineering for the catapult is too large, and it's not realistic."
Even Wu Huade denied this plan.
All kinds of plans will not work, and the aircraft carrier will soon be docked.
"It seems that there is only one plan." At this moment, Nathan spoke.
Hearing Nathan's words, everyone's eyes widened: "What is the plan."
Major Nathan has a lot of ideas. In the Navy, it has been spread for a long time. All kinds of weird ideas were first proposed by Nathan. Like the idea of tying the Phoenix missile to the Mozu, it is Nathan. I brought it up first.
Everyone expected Nathan to come up with an earth-shattering plan, but Nathan disappointed them.
"Change the engine for the Tomcat fighter," Nathan said.
What Nathan said is the most normal plan.
Look at the succeeding Su 33 and F-15, they can all take off with full fuel and bombs. Although it is the farthest take-off point of 195 meters, and its own side is only 167 meters, the Tomcat fighter has the advantage of variable swept wings. , You can reduce the required take-off speed.
The reason why the current situation appears now is because the Tomcat's engine is not powerful. If the Tomcat fighter can have a powerful engine, it must be able to achieve a distance of 167 meters and be able to take off with full fuel.
You don't need to hang six phoenixes, even if you only hang four to take off, it is already very tough, and then further reduce the requirements, at least full of fuel, hang two phoenixes, four sparrows and four rattlesnakes, right
If this is the case, how much thrust does the engine need
11.5 tons, Nathan has already thought of this figure, and now, there is a difference of about three tons of thrust. If the two engines each add 1.5 tons of thrust, it will be enough.
Although Nathan prefers the f100 or f110 with a thrust of more than 12 tons, it is only 79 years. Both engines have not matured yet. However, this does not mean that there is no way for him to do it.
At this time, Allison should have completed the tf41 upgrade plan, right
The tf41 is a modification of the Spey engine. The model without afterburner was used on the attack aircraft, and the model with afterburner was used on the Tomcat fighter. This is a situation that will not exist in later generations. It is driven by Nathan. Achieved.
At the same time, the current tf41 does not increase the thrust, so it is still inappropriate, and Allison has also launched an improvement plan for this engine, with the goal of increasing its power to 11.5 tons.
I don't know how they are progressing. After all, this is not a newly developed fighter plane, it is just a modification. The progress should be faster. (End of this chapter)
