New Mossi Performance. Wow.

[SmokinLoon]

Boozeman, at sea level the difference is 1mph.  At 5,000ft it is 13mph.  At 12,000ft it is 4mph in favor of the new one.  At 13,000ft it is 2mph in favor of the new one.

Your testing involves %50 fuel, no ords, etc.  Does the chart and actual flight performance match up when the chart weights are the same?  I'll do some more testing to find out.

I'm still having a difficult time accepting the new Mossi's speed/climb chart as accurate.  There is much evidence pointing to a faster Mossi, not a slower one.

My testing is 50% fuel and no ordnance for both the new and old ones.  I still have AH v2.18 in another folder so that I can test both of them.

Also, keep in mind that all the charts Sherf and I worked on were WEP performance.  It is entirely possible that the old Mossie's MIL was modeled with ejector stacks and only its WEP was being hampered by flame dampers.


The other thing I am having some trouble with is climb rates.  Even when I have my speed at 170mph in autolevel and then switch to autospeed (what most think of as autoclimb) and go to +18, 3000rpm it doesn't smoothly hit maximum climbrate.  It spikes to over 4,000fpm, both new and old Mossies, before oscillating above and below 3400fpm on the new or 3300fpm on the old one, eventually settling on about those speeds.

This report suggests the climb on WEP should be a bit better:

ADDENDUM TO REPORT NO. 74 on TACTICAL TRIALS - MOSQUITO VI
........
6.  The climb has also improved considerably at full power so that the Mosquito can pull up from low level into a cloud 2,000 ft. above it in less than 30 seconds from fast cruising.  Near the ground the rate was approximately 3,800 ft. per minute in a steady climb.

So the 'dog-leg' ejector stacks keep the ex gasses from the rad intakes?

Having never flown a Mossie for real, I can only imagine, but the Cartoon Mossie I flew tonite seemed much more like the ones I've read about.  It can really move.  Always felt slow in the old AH Mossie.  This one felt right.

Agreed

[SmokinLoon]

I also have a copy of AH 2.18.8 that I have been using for testing purposes.  I can get you any weight you like, just tell me the configuration.

I recall the original charts were at 22,221lbs, 100% fuel and 2,000lbs of bombs.

Could you please verify weights on the old Mossi at 25/50/75/100 fuel, w no ords???  Thanks! 

[Karnak]

Sure, I get off work in 2 minutes.  I'll do it when I get home.

AH v2.18.8, Mosquito Mk VI, overload ammunition, no ordnance weightsL

25%: 17,913lbs
50%: 18,727lbs
75%: 19,541lbs
100%: 20,354lbs

And away from the leading edge of the wing.

Thanks for posting the fuel weights.  

The only way I am able to replicate the new Mossi's given weight for the speed and climb charts it to take %100 fuel and the 50 gallon DT's.

Karnak, could you see what it takes to replicate the previous Mossi's 22,221lbs weight for their speed and climb charts?  If they did use 2000 lbs of ord, the discrepancy between the 2 versions is even higher than what is listed.    

EDIT:
btw... there must be a decent jaunt in the speed performance chart from 15k to 20k, Im trying to get the Mossi to settle into a speed at 20k.  So far it seems to be 376mph TAS with a weight of 17,752 lbs.  I lifted from the 20k field, went level flight with %50 fuel, and watched. The best WEP performance I could reach was 384 mph TAS, weight was 17,610 lbs.

I did the same for 16,500 alt as well.  All recorded speeds were reached via acceleration.   

16.5k alt @ 17,733lbs: MIL 364mph TAS, WEP 386mph TAS
20k alt @ 17,752lbs: MIL 376 TAS, WEP 385mph TAS

I have no problems with the Mosquito and have always liked it.   The performance has always good, but this latest re-vamp has me enjoying it more.

I hope we get an updated performance chart on the scores and stats page soon.
