HTC Nice Job on B-26B Flight Model

[funked]

Just for fun decided to test speed and climb.  The only information I have on the plane is from Joe Baugher:  http://home.att.net/~jbaugher2/b26_4.html

Baugher's site says:
270 mph Sea Level.
282 mph 15,000 feet.
1200 fpm Initial Climb.
Service Ceiling 21,700 feet.  (Service Ceiling is the altitude where climb = 100 fpm).

I did my test as the USAAF did - with the plane fully loaded with fuel and with the standard 4,000 lb bombload.  I was quite surprised to see that the AH B-26B matched the figures on Baugher's site within instrument error!  Nice job!

funked, we gotta find you a woman.
 

WTG HTC on the flight model.

LOL

Ya gotta find him a woman who won't run away from the sight of him first....

Try the Lancaster... I smell bacon

Women sense my power and they seek the life essence. I do not avoid women, Mandrake err Maverick.

Maby ya need a woman that conforms to the USAF standards (within instrument error)

Juzz I can't imagine the real Lancaster performed much worse than it does in AH.  I don't have any data for the Lancaster III.  But the one in AH will barely do 750 fpm with max bombload and half fuel.  With full fuel it needs a runway about twice the distance of the one we have in AH.

So I doubt there is any porcine odor coming from the Lancaster FM unless you are trying to say it's UNDERmodeled.

The lancaster was a very agile plane unloaded - I once read of a pilot doing a slow role in one. I talked to a lanc pilot at the Battle of Britain Memorial Flight Day at RAF Conningsby - he said it was a great plane to fly fully loaded or unloaded.

No, Funked, women see this:

 

And then want to be your friend.

That's just.... disturbing.

The Lancaster, well it's both undermodelled, and overmodelled.  

Here's a rant I wrote up a little while after it was toned down from it's original overmodelled FM(The one where it climbed at ~2000fpm empty.  )

In AH, engines are rated at 3,000rpm and +16lbs boost for unlimited time - WRONG! - Merlin XX was rated at 3,000rpm, +16lbs boost for only 5 mins, climb rating was 2850rpm, +9lbs boost, maximum continuous cruise was 2650rpm, +4lbs boost.

All AH testing was done at an estimated 60,000lb AUW (6 x 1,000lb bombload; since a 14,000lb bombload and full fuel was supposed to be 68,000lb AUW)

At 60,000lb AUW, lift off is at 110mph+ - WRONG! - at 63,000lb AUW, lift off was at 90mph IAS!

With 3000rpm, +16lbs boost, it maintains 750fpm up to 13,000ft, then slowly begins to drop - WRONG! - Should maintain ~700fpm up to ~ 9,000ft, then drop to ~500fpm holding to ~16,000ft, then dropping to service ceiling, but with the engines at climb rating of 2850rpm, +9lbs boost. Reaches 22,000ft in 39 minutes, should be at *least* 44 minutes or more.

Ceiling is - WRONG! - Should be around 22,000ft. As I got somewhere near 28,000ft - CLIMBRATE WENT UP!?! I gave up after that.

Top speed seems reasonably accurate. Cruise, however, is  - WRONG! - at maximum continuous cruise of 2650rpm, +4lbs boost, the aircraft simply drops out of the sky, when it should be doing over 230mph!

The "correct" numbers presented here are from Boscome Down testing of Lancasters which were in service with Bomber Command Squadrons.

Funked, here's some charts for ya

what type and background color?

Dowding I read the same thing - a guy standing next to the pilot floated during the roll - feet off the floor, just suspended in space.
