  • The Nakajima Ki-84 may have been Japan's best fighter of the war, furthermore, it's solidly in the running for best fighter of the war period.
    Information on this airplane is scarce. There isn't a lot of primary source data on the Ki-84, and a lot of the secondary stuff is contradictory. In this video I have pieced together what I can and I think the result is a fairly comprehensive look at the design and technical details of the plane. I hope you like it.

    Note: the La5Fn/La7 engine may have been lighter than the one on the chart by about 90kg. That would make it about the same as an R-2600, but still heavier than the Homare. It's hard to pin down Soviet stuff due to variations in standards.

    The mention of the water methanol mixture in the p47, allowing less fuel consumption at WEP than at military power, brings this full circle to the original thought of using it to extend range in bombers instead of using it for additional power.

      You must calculate the mass of the many hundreds of gallons of water and subtract it from either the bomb load or fuel fraction.
      Then, determine if that tradeoff for water which is 1.25-1.38x heavier than Avgas/Jet fuel, and having exactly zero BTUs of energy per gallon, would indeed extend the range.
      If you are spraying 50/50 methanol into an engine and it makes more power with lower gasoline consumption, are you ignoring the many gallons of dragster fuel you are pumping in from another tank? Not hardly. And if you consider that Methanol has a much lower energy than gasoline, and water has zero energy, you will find that the engineers knew what they were doing specifying a certain amount of Avgas instead of methanol.

      I’m wondering whether that was part of the motivation here; Japan was always reliant on imported petroleum, but alcohol derivatives are probably something they could produce within the home islands, allowing them to stretch the fuel supply without sacrificing performance? Also, additional head cooling could help compensate for less capable metallurgy.

    The drastically reduced rate of fire for the cowl-mounted machine guns has to do with a combination of primer quality (and its degradation over time) and the gun's "lock time", the time it takes for the firing pin to move foreword and ignite the primer after its trigger is pulled. Variations in either or both of these reduce the window in which the trigger can be pulled and the bullet be assured to miss the propeller. The speed at which the action operates and is ready to be fired again also has a significant impact as well. Slower action speed and higher lock time can have an outsized effect at certain engine RPM's which cause a propeller blade to be in the way just as the weapon is ready to fire again.
    The German electric ignition of primers eliminated the lock time issue, of course.

      Im quite surprised really that they/someone didnt invent an engine driven gun. Like a mechanically connected to the crankshaft gun that had like a side face toothed gear "clutch" where the gun is always ready to fire, but when you pull the trigger it engages a clutch which can only lock into say 3 or 4 orientations (to allow for the timing to not hit the prop) which cycles the mech untill you let go and it disengages the drive, wether by solenoid or cable and clutch fork

      @@Colt45hatchback That is pretty much what some of the synchronizer setups were. They had a mechanical or hydraulic device activated by a cam connected to the crankshaft to prevent the firing pin from dropping with a blade was in the way (or move into the way in the time it took for the firing pin to fall, primer to ignite the powder and send the bullet out of the barrel). Most setups eventually went to a hydraulic system (tube filled with liquid) instead of cables or mechanical linkages to minimize the number of components that could stretch or wear.
      Some guns, like the later versions of the 20mm MG 151 used electrical primers, so the device would prevent electricity being sent to the primer when a propellor would be in the way.

    Very informative and interesting video as always Greg. Just wanted to point out, that whilst part of Nakajima Aircraft Corporation became 'Fuji Heavy Industries' (Subaru), another large part of the company was building engines for another car making company. This company merged with the engine supplier and became Prince Motor Company. Prince are famous in Japan for being the designers of the 'Skyline' car (amongst others). The company later merged with Nissan who have continued the name 'Skyline' through to present day. So I think it fair to say that Nissan's best cars can trace their heritage back to Nakajima, as much as Subaru can... (apologies if other posters have already mentioned this).

    Re: "water injection," the following is from my Dad's squadron's (VF-19) combat history of their tour in the western Pacific in the summer and fall of 1944: “After having transferred twenty planes to ComAirPac the squadron received thirty seven new F6F-3’s. Twenty of these new planes had water-injection engines, the first water injection planes in the Hawaiian Islands… About this time, the squadron was notified that thirty seven F6F-5’s had been assigned to VF-19, and Ralph Clarke, another experienced Grumman representative, lectured on the similarities and differences of the F6F-3 and F6F-5. However, before delivery of the new planes could be effected; orders came through for the squadron to depart. Within two days, all the non-water injection planes were exchanged with VF-18 for water-injection planes.” They flew aboard the USS Lexington in early July, 1944. Dad was the squadron engineering officer, and squadron pilots likely well-understood the combat advantages of the system.
    While he did face (and shoot down) two Ki-44 Tojos, to my knowledge, Dad never faced a Frank, though I've seen a painting of one of the squadron's final missions in the Philippines in early November, 1944, during which a couple of VF-19 pilots combined to down a Frank in a low-level fight near Clark Field.
    If it helps any, after my own lumbar surgery (decades ago) I was able to resume normal activity a couple months later, with the exception of lifting dead weights of 50 lbs. or more, and I stayed away from golf for a couple decades (no loss, I wasn't very good at it). In fact, I coached fast-pitch softball (including swinging a bat for fielding drills many, many times) for 15 seasons, until I retired from teaching, beginning a few years after the surgery.

    More prototypes also allows for testing in different environments and extremes. I'm not sure this was a common practice in WW2, by any nation, but it is an advantage. You can test one prototype in arctic conditions and another in desert or tropical conditions. The Germans seemed to have had a multi-tiered prototype system as well. They produced "V-n" (where n is a number) variants and then they produced "A-0" aircraft which were pre-production prototypes.

    The likely explanation for why armor was "worth it" is that it is quite unlikely to get a perfect 90 degree hit on the armor. We know that a hit at any oblique angle will increase the effective thickness of the armor and reduce the likelihood of penetration.

This guy was a better carrier pilot than combat pilot. (I would have put the plane in the water rather than attempt landing on a straight deck carrier.)

    In my 45 years of working in aerospace, I have found that the one thing all prototypes have in common is that they are fabricated with little or none of the tooling that enables serial production. Lack of tooling (among other things discussed) could have contributed to a necessity to continue manufacturing prototypes.

    regarding the gun trigger on throttle. having the trigger on stick affects the finer inputs needed to aim steady when pilots squeeze too hard which affects accuracy. trigger on throttle solves that issue and it also helps to compartmentalize tasks. "right hand for aiming" "left hand shooting"

    Yeah, Spitfire flaps aren't meant for use in flight. Only when landing, when you actually want the speed brake effect as well as the added lift. They only have a full-down setting, not in notches like the P-51 or continuously adjustable like the P-47.

    Also, a smaller displacement per cylinder allows for a smaller combustion chamber and, consequently, less probability of detonation. That enables the use of a higher compression ratio. Just a thought.

    I'm a bit surprised just how good this design is, looking forward to the next part. Although if the Ki-61 was already significally hindered by the lack of "Division 1" pilots then things could only be worse for this aircraft. If possible, I would like a quick assessment of the aerial situation for Japan at the time of the Frank's appearence, as I'm pretty sure most people (including myself) only know that "it was getting really bad".

    • @vlad78th
      @vlad78th ปีที่แล้ว +2

      I'm not sure about japanese army figures but from what I read about navy pilots I can make an educated guess. At the start of the war both army and navy had a very strict program selecting only the best pilots. Navy pilots quality was above army as the training was even more intensive and required strong navigational skills. Young pilots started frontline duties with 700 flying hours in the navy and 500 in the army. Yet most pearl harbour veterans either died or became not able to fly anymore by the end of 1942 after the carriers battle of that year and the attrition caused by the Guadalcanal campaign. In the army, the situation was similar after the air war over new guinea which lasted until 1945. New Guinea was even called the green graveyard by japanese army pilots. During 1942 new pilots were of good quality but the attrition rate forced the japanese both in the army and the navy to drastically decrease the time given to train new pilots. Flying time required was more than halved while US pilots were not qualified without at least 525 flying hours. By 1943 allied units witnessed a sharp decline in the quality of japanese pilots and the situation only worsened when 2nd generation of US fighters appeared against zeroes and oscars. The US submarine campaing started to bear fruits and hit japanese supplies of oil sharply making pilots training all the more difficult. I read somewhere japanese pilots were qualified with a whooping 40 flying hours at the start of 1945. So in essence when the Ki-84 appeared most skilled pilots were dead and they were too few Ki-84 to really make a difference and the machines were unreliable given the poor experience of the workshop building personnel and the lack of skilled mecanics and the quality of the fuel used had dropped hindering further the perfomances of japanese planes. Bear in mind the KI-84 first saw combat when the Imperial Japanese carrier based pilots were being slaughtered during the Marianna great Turkey shoot. 4 months later Japan used Kamikaze attacks because conventional aerial attack could not reach US targets anymore. So yes, it was getting really bad.

  • @aceofhearts573
    @aceofhearts573 ปีที่แล้ว +3

    34:53 hey Gregg I might be able to explain this. The Japanese Navy licensed the MG131 to use as their back gunner machinegun. They did not use the electronic firing and used the original percussion ignition which lowered the firing to 750rpm from the original 900rpm. Japanese navy said they did this because the heat and humidity of the tropical environment would damage the electrical connections and since they would not use their Type 2 as cowling or even wing mounted machineguns only ad back gunner this increased reliability

    Love your presentations. Beyond Jack Webb saying "Just the facts, mam". Because of my involvement with motorcycles since the '60's when you were comparing engine parameters to HP, as you went through the differences my head was saying 'RPM'! The Japanese have been some of the best and earliest reguarding that ratio in road racing through the years since WWII. Having said that the Italians (Moto Guzzi) had a double overhead cam V-8 in the early 50's. Seems tyres were the limiting factor - go figure.

    As a guy who prefers Japanese motorcycles, but grew up with British and American bikes; and has been flying since the seventies, I love the Japanese WW2 fighters, and so, I really enjoyed this video, Greg. (Honda made the piston rings for, mostly the Mitsubishi engines for the Zeros, but years after the war, when Honda was racing Grand Prix motorcycle engines, they were running much higher RPM than anyone else. Reliably.) Having only twice needed to swing a prop-a little 172 I am a big supporter of electric start! The late '70's were the epitome of GA; affordable, reliable, amenable, and familiar. It's all messed up now.

    @HandFromCoffin ปีที่แล้ว +4

    In the .50 cal pen also don't forget those are for a perfect 90deg angle. So the vast majority of those shots are not going to be at right angles. So you've got distance, hitting other objects, thickness at the angle of impact and ricochet all to factor in. I am sure there is a formula or guides to figure out how thick the pilot armor should be to save the pilot in X% of hits. I'm sure they've got a ton of info on shot angles and ballistics tests to figure this out.

  • @michaeldenesyk3195
    @michaeldenesyk3195 ปีที่แล้ว +9

    Great video Greg. I am particularly interested in how the Allied test pilots learned how to fly or even start the engines on captured German, Italian or Japanese aircraft. I get it that they are test pilots, but even test pilots have a briefing or designer notes and information on engine performance to refer to before they strap an airplane to their butts. Did they capture manuals as well as the complete aircraft? As you can probably guess, I am not a pilot so if my question seems wonky I beg your indulgence and patience. Great videos, and thank you for putting these together.

      Translating written German into English is not difficult as far as engineering is concerned. Very little is lost in translation there. Grammar, syntax, different word meanings etc. are not a concern there. The main difficulty would be conversion from metric altitude/pressure/speed to non-metric. As far as start ups etc. you need a manual even if you transit from lets say a P47 to a P51. That being said there are similarities. You wouldn't fly a captured plane though before your mechanics had had a very good look at it to see how it works. Just my two cents.

  • @juanordonezgalban2278
    @juanordonezgalban2278 ปีที่แล้ว +4

    Regarthing the low fire rate of the sincronized machineguns, it may have had to do with avoiding cookoff: For the weapons to be syncronized with the propeller, they have to be close bolts design. In these a round is siting on the barrel ready to be fired, and if the gun is hot from previous shots, the round might ignite on it's own. A low fire rate would help keep temperatures low. In free fire aplications open bolt can be used, where a round won't be loaded until the trigger is pressed.
