Need Ki84 HAYATE's data! - Aircraft of World War II

Steven Que · 04-24-2009, 10:59 AM

Hello guys.
I need some schematics for Ki84 hayate
or cutaways.
These picture and datas will help me to do report of aircraft.

Thanks.

Hi Steven Que!

You have posted three times for a question in half an hour.
What kind of report are you going to do in a so hurry?
I'm very curious. You will be able to get the necessary data from here -

Airwar.ru(1)
Airwar.ru(2)

Good luck!

I have this that may be of some help.

Thanks guys.
My report is analyse the aircraft's stability.
Then I choose Ki84 to analyse
then tell the aurcraft is good at stability or not.(most craft is stability)

I like these picture

oh! I forget that!
What is the scale of these picture?

Shinpachi · 04-25-2009, 03:56 AM

What a great report you are doing!
I want to know the result if Hayate was stable or not.

The scale depends on the size you draw or print on the paper.
You can calculate it refering to the list Micdrow shows or the list attached here if it's meteric system.

Thanks.

Additional Information.

Hmm...
These data is the part of I need
But I need the data from aerodynamic's concept now
Center of gravity's location
Aerodynamic center on the wings
Then I can use equations to analyse
Maybe need the airfoil's code to find that(maybe NACA 4,5,6 digit)
Thanks

I would have figured that is ALL the data that you would need from the start. I am somewhat surprised that it took this long to make this particular request. Unfortunately, the only folks I can think of that would have this information would be the folks that rebuilt the only existing Ki-84 that was sold back to a private Japanese buyer or the folks at Wright Patterson or TAIC who tested the aircraft when it was captured or perhaps the Japanese private owner of the only existing aircraft. I am guessing that if you are lucky, you will find some pilot's reports of the captured aircraft. Actually finding the weights and balances manuals and other such data would be great. If you do, please share.

would be usefull to know the speed at which power setting it's obtained

Micdrow, where do you and other people get these awesome technical listings? All the books I have just list the standard "Weight, maximum weight, maximum speed, cruising speed, armament, number produced...etc." None of them go into wing loading or any of that other stuff on there....

Ivan1GFP · 05-11-2009, 10:43 PM

Hello MacArther,
I have no idea where folks are coming up with some of the more esoteric data. Wing Loading is no great information. It is easy to calculate once you have other commonly available figures. The table I posted was just something I found online. I should scan and post the marked up copy that my wife translated for me because I believe the only person who can read it at the moment is Shinpachi.

Hello Shinpachi,
How did you get the Center of Gravity? Is it via observation of the wing planform and the likely center of lift as I am reading from your projections of the leading and trailing edges?

- Ivan.

Shinpachi · 05-12-2009, 12:12 AM

Hi Ivan1GFP!

The center of gravity is(or was) always on the main spar.
To get the MAC location, I simply obeyed aviation basics.

In order to get informations, I only rush into the data mountain like Kamikaze(or Micdrow)!
Cheers everyone!

PS: New design of this forum is sophisticated and good.
I like it.

Ivan1GFP · 05-12-2009, 06:02 PM

Hello Shinpachi,

I am thinking that the CoG on the Main Spar is something that can not be assumed about various aircraft designs. It may be optimal and intended in the original design, but a lot will depend on the disposable loads that are carried or any design or equipment changes.

The P-51 and P-39 are two cases where CoG changes pretty seriously depending on the load.

- Ivan.

Shinpachi · 05-13-2009, 04:19 AM

Thanks Ivan1GFP for your comment about the center of gravity.
Yes, I know it is too rough to say every main spar is on the center of gravity as it depends on the wing design. Sorry for my so simple explanation last time.

Some operation manuals for the old Japanese fighters say "Main spar(exactly forward spar) supports the whole weight of the aircraft" and, in fact, the center line of fuselage and the main spar crosses on the center of gravity. I think the center would be an average point of fully-loaded and empty conditions though I find no exact explanation about it yet.
