Testing the n1k
« on: December 04, 2000, 03:02:00 PM »
After being amazed at what the n1k can do immediately after takeoff; and never having actually flown the plane myself, I decided a little test would be a good idea.  My intention was to see just how well the n1k held it's E, that way I would know what it could do.

Here's what I did:

Offline, pick n1k, 50% fuel.  (I figured for base defense this is what they would pick.)  Immediately after takeoff, try to loop.  Well guess what, I was able to loop the N1k immediately after takeoff!  I then continued to loop 10 more times before I decided the N1k holds it's E well enough to loop infinately many times.      At the top of the 11th loop I pulled negative gs and then tried to continue into an outside loop.  Had I 50 more feet of altitude I would have been able to pull it off.    

loops.ahf

Now tell me, is this accurate?  Could any WWII fighter loop immediately after a 170 mph takeoff and loop continuously?  Note, I was pulling 5 gs at the bottoms of the loop.  I tried this with the p51 and it couldn't even finish 1/2 a loop.

I've decided now that something is definately amis with the N1k FM.

La-5FN can do it w/100% fuel.  Was actually flight tested by the VVS, and could do loops at 186mph.

Incidently, USA fighters were generally the biggest, heaviest fighters among combatant nations in WWII.  Not surprised a P-51 couldn't do loops, since no American fighters were known for their power loading, and in fact had the worst figures of the lot.

I did a quick check at Joe Baugher's page on the N1K2-J. Loaded weight was 8818lbs, wing area of 252.95 sq/ft, which comes out to 34.86 lbs-sq/ft. Power loading, using the given engine rating of 1825 hp at 5740 ft, comes out to 4.83 lbs-hp. That wing loading is about the same as a loaded Bf-109 E7. Either this thing is a Japanese Bf-109 E, or something funny is goin on here.

As a reference, a P-51D has a wing loading of 43.34 lbs-sq/ft and a power loading of 5.95 lbs-hp. Again, according to Baugher's figures on his pages.

In practice loops are more like a lower case "e" where you loos a bit of altitude with each loop due to the lose of energy reqiured to make the plane perform the loop. If you can take it off and get to 170 then i will assume (and it is an assumption) you would have been no more than 1K of the deck, now to do 11 consecutive loops without hitting the ground you cant have been loosing any more than 90 feet per loop. This to me seems a bit strange.

BTW, the N1K2 was not a light fighter - it was quite big and heavy for a japanese fighter.

Bloom,
base defenders and short legged quakers takes 25% fuel (Niki's tanks carry a lot of fuel). Try it again and do 20 loops.

RAM, when the hell are you going back home?

The Niki also has an incredible roll rate.  Just take off, get level with some speed, then chop the throttle, kick full right rudder and yank the stick back

I almost hit the ground on the first loop, but actually seemed to gain altitude on each successive loop.  If I had decided to continue looping, I'm sure I could have continued to loop until my fuel was gone.  After loop 11 I pulled -3 Gs until pointing straight up.  I then tried an outside loop, but unfortunately I was 10 ft too low to finish the loop.  (Plane was pulling out when it hit the ground.)

Guys, these weren't lazy loops either, I was pulling from 4 to 5.5 Gs at the bottoms on every loop.  Unless I had a greater than 1 to 1 thrust to weight ratio, I should have lost altitude.  I'm quite convinced that I could actually have slowly climbed gained altitude by continuously looping.

Take a look at the film...

The link is fixed, it's called loops.ahf, NOT loop.ahf.

This time, just like last time, I looped immediately after the wheels left the ground.  This was followed by 26 more loops before I decided this was pointless.  I then hammerheaded, noting the n1ks amazing low speed characteristics (torque?).  After that I decided to test how big of a hole the n1k could make in the ground.  

You guys should note that I actually was gaining altitude until my wep ran out.  (Field runway is at 500 ft, bottom of loops increased to around 580 ft.  Does this mean the n1k actually gains more E than it loses in a loop?    Um, unless the n1k has greater than 1 to 1 thrust to weight, is this even possible?   )  The hammerhead that took only 1.5 seconds to do was fun too.

Enjoy!

Nothing new here.

Nikis doesnt lose E---------->we already knew that

Nikis dont have torque-------->we already knew that (take a look at the tiffie too, pliz)

Nikis do have nearly same low speed handling as A6M5--------->we already knew that.

The only thing I didnt know was the N1K2 performance over 20K. Maybe because I rarerly went over that altitude and didnt care to see how did the UFO act there.

 

(BTW If you find my attitude a bad one, take a look at those films. The BS of the UFO is leaking out of each one of them. some of us have been saying this since 1.04 came out, and had to stand against whiner calls. Now tell me why doesnt a N1K2 burn E in a 5G loop).

Hey RAM, with 25% fuel and wep left, it actually gains E in a 5g loop.  Get your fact right please.

The a6m can do an immelman at 120-130mph and then keep looping.

The Spits have similar performance.

Of course the N1K is modelled correctly.

Fix the 190A8's climbrate and turn ability - it is way too good compared to these planes. I mean, it can abrely take off and fly level for the first 30 seconds.
