Chapter 618 Well, a junk collector... dismantling things here and there, it's inevitable that t
Don't think this is a joke.
Let's take a look at the radar transmitter magnetron, which is installed in the launch bay behind the radar dome on the back of the aircraft.
The single-tube thermal power is 1.5kW, but the ridiculous thing is that its efficiency is only 40%, with the remaining 60% of the energy being converted into heat. The heat generated when electrons bombard the anode, plus the resistance loss of the focusing coil, is enough to raise the anode surface temperature to 600°C.
Hmm, it's still 200 degrees Celsius away from its melting point of 800°C.
Don't rush, add the 0.4KW of the radar receiver front-end amplifier, plus the 0.1kW of helical focusing magnetic field dissipation, and these will easily raise the temperature by more than ten degrees...
You think that's all? Dude, you haven't even calculated the switching losses of the modulator's thyristor!
峰值电流200Ax管压降50V=10kW脉冲，均方根热功率1.2kW。更讨厌的是，这会我们用到的，依旧是老毛子的氢闸流管tГn1-10/16，氢介质会在超过150c时电离失控……
So even if our comrades can withstand it, these fragile electronic components can't...
Keep revising!
Come on, Laplace's demon, give our comrades a chilling shock!
When we tested this vortex tube last time, Jiang Xia got some and put them in the machine factory's warehouse. They came in various sizes and were practically plug-and-play. It's just a bit of a hassle for Old Wang to keep circling around Beijing.
Well, I don't know which genius invented the security measures, but to get into this base, you have to follow a certain route. If you miss a turn, you might be greeted by "Cannon Pipe No. 1" (RPG) being produced at breakneck speed the next second.
Regardless of the fact that Old Wang had just finished carrying bamboo and now had to go find the vortex tube, heaving along.
After listening to Jiang Xia explain how vortex tubes work, Xiao Mo asked a pointed question: "Engineer Jiang, vortex tubes are good for cooling, but according to your description, they need compressed air to drive them, right..."
"That's right! It only needs compressed air to operate, no external power source required! Aren't I thoughtful? This base has plenty of compressed air cylinders!"
That's true. It must be said that Jiang Xia considered things very thoroughly; the MiG-15's starting method includes a high-pressure gas cylinder-driven approach. However, this is mainly a special starting method for emergency situations or field conditions.
High-pressure gas released from a high-pressure cylinder enters the engine through a pipeline, driving the turbine to rotate. Once the turbine reaches a certain speed, the fuel system begins to inject fuel, and simultaneously the igniter ignites the fuel, starting the engine...
In other words, you really can blow a breath and make an airplane fly...
Where is the gas cylinder located?
"install……"
What a load of crap! The entire bomb bay of the Tu-4 is already crammed full of all sorts of radar terminals—it's overflowing!
"That's why I hate taking over projects halfway through. This damn Map-4, I'll replace you sooner or later!" Jiang Xia rubbed his chin, which was now covered in thick stubble, with some annoyance.
"Wouldn't it be better to ask the Air Force for a Tu-16...? Maybe they could even attach a few 'Big Firecracker No. 2' missiles..."
"Forget it, no way, the structures are completely different. If we bring it back to work on the fuselage structure, it'll be too late..."
Jiang Xia couldn't figure out that vague point no matter how hard he tried, so he got angry that he squatted down and tore the draft paper into little figures.
Take off your shoes and take a picture!
"You bald eagle, why don't you go and fight the bear head-on instead of causing trouble for the little white rabbit!"
"You Russian bear, why don't you make some more noise in the Cigar Country to draw more fire, instead of running off to be a construction worker building walls! They're going to be torn down in a few decades anyway..."
The surrounding soldiers and researchers shrank back as they watched the berserk little ahoge, and continued to swing their sledgehammers at the copper foil.
Eighty...eighty...
For a moment, the sound of hammering echoed through the air, even suppressing the roar of the snowplows speeding merrily in the distance.
"Old Pang! Didn't you think the 'snow blower' was too wasteful? Why are you still blowing snow?"
Pang Guoxing shouted in grief and indignation: "I don't know which idiot said he wanted to test the continuous use time! Do you think I'm bragging? The track was cleaner than my face!"
"Test my ass! That engine's entire lifespan is only 300 hours. Stop it, stop it..."
Pang Guoxing was frustrated and turned to leave.
"After it stops, take the low-pressure compressor of that WP-5 turbojet engine and bring it over to me..."
Pang Guoxing tripped and fell dramatically to the ground.
"Brother, I know you like to rob Peter to pay Paul, but this is really unnecessary... There's a bunch of old BK-1s in the warehouse, take them all! Keep the 'Snowstorm Truck' for me!"
"Jiang, are you thinking of installing another engine?"
"No, we only need the compressor inside... Since installing gas cylinders won't work, let's install an air duct! Air cooling is just as good!"
……
"The low-pressure compressor is disassembled! Where does this go?"
"What's the rush? Take down that turret too!"
Jiang Xia pointed to the two-barreled self-defense turret that had been preserved in front of the radar dome and directed everyone to continue dismantling the machine.
"No, Engineer Jiang! Didn't you say you'd leave this turret for us to increase our sense of security?" The Tu-4 crew was as happy as they were when they removed the BK-1 engine, and now they were just as sad.
Jiang Xia originally wanted to dismantle this turret, but the crew members begged him for a long time before it was preserved.
这个时候的大型机驾驶员，身上不装几个炮塔，真的不好意思出门。本来图-4身上装载了10挺口径为12.7毫米y6型航空机枪，10部口径为20毫米6-20Э型航空机炮，5部口径为23毫米HC-20型航空机炮。
Everyone feels very safe flying this plane. But with all this fuss, the only remaining 23mm HC-20 aircraft cannon is about to be gone. How can people not panic?
"We still have six 20mm cannons for you to shoot birds, what's the panic!"
"It's useless! Forget about shooting birds, it can't even hit a bat. Isn't caliber supposed to be the ultimate weapon? If we really have to dismantle it, we'd rather keep that 23mm autocannon!"
"Tch, six 20mm guns are more powerful than one gun!"
"We're short-handed! We need to fly the planes, and the operators need to monitor the radar..."
"Are you guys stupid? Just bring over the MA-7 fire control system! We already have an airborne radar, so it's practically target and fire anywhere. The fire control computer for this system can utilize the Doppler radar's processing terminals, so we don't even need to do anything special. We can just integrate the control console directly into the P-type display..."
Jiang Xia sprayed saliva all over the captain's face. The captain silently grabbed a snowball and wiped his face with it...
"(⊙o⊙)... You guys don't know about the MA-7 fire control system? It's the one from that 'demon among demons' that we got from the Northeast, right?"
The crew members shook their heads like rattles...
Looking to the side, Xiao Mo continued to rattle his drum.
"Engineer Jiang, as I told you, we're on the same production line as them..."
Forget it, forget it. I guess it's some confidentiality regulations that's causing the research results to lag behind. It doesn't matter. I scanned it out of curiosity at the beginning, so I still know the system components inside. Let's continue with the modification!
While directing everyone to dismantle the circular turret behind the wing's front spars, Jiang Xia drew up a blueprint for a universal joint and handed it over to the logistics personnel for manufacturing.
Very important!
By connecting the power take-off shaft of the engine (AW-73TK piston engine) inside the wing using a universal coupling, the compressor rotor can be driven!
While waiting for the coupling, Jiang Xia casually installed a P-type display in the cockpit to serve as the interactive interface for the original fire control system.
Here, target information can be obtained, and based on the firing data provided by the fire control computer (actually the radar signal analysis end, but the effect is similar, only lacking the parameters of the optical aiming system), the machine gun can be operated to carry out the attack.
At the same time, the firing system of the machine gun was connected in a simple way, so that the gunner did not have to pull the trigger, but only needed to reload the ammunition...
Want to know how it's linked? Forty years ago I could say it openly, but now... well, not really, bro, don't be so irritable.
Yes! Overall, the features are very advanced!
The Tu-4 crew members were all smiling...
However, with all this commotion, Jiang Xia inevitably got a little carried away by his comrades.
Is this even an early warning aircraft?
If the 23mm autocannon had been retained, and a 105mm howitzer had been added, wouldn't it be similar to the Bald Eagle's "AC-130"?
Is this youth version of "gunship" any good?
