Author Topic: Supercharger and performance oddities on the Mossie (Read 240 times)

Pyro stated that the fuel consumption model is based on Merlin 21s. Does that mean the boost model is too?

The performance model seems to be based on Merlin 25s.

Currently in AH2 the Mosquito's best speed of 380mph is obtained at 13,000ft. However, the boost is only at +9½lbs as the supercharger isn't providing enough pressure.

At 17,000ft the Mosquito maxes at 372mph while the boost reads a full +14lbs.

Is this correct, or is it a disconnect caused by differing engines for differing parts of the model?

(It is nice to see the boost change dynamically. You can really see the second stage kick in on the Spit XIV)

It's disconnected. It does need some adjustments, but really I just kind of put it together quickly because I would like to go through a full review of its performance. I just can't do that now. I'll take a look at the discrepency between it's current performance and what is displayed on the boost gauge and make a correction.

Thanks Pyro.

the graphic model shows covering of the exhaust tubes. wasn't the VI model a day-time fighter-bomber? What's the covering for?

(and I suppose it takes a few mph of the top speed)

It is a flame damper and it takes off about 10-15mph. Many FB.VIs had them, and many lacked them. The best performance data available for the FB.VI is for one with the dampers.

Here is the chart:

The Mk VI in this chart has the flame dampers. The Mk 33 is a navalized Mk VI without the flame dampers and with a four bladded prop. The Mk 33's curve is probably very close to the Mk VI without flame dampers.

Mk VIs operated day and night in Intruder and Day Ranger missions.

The specific Mosquito (artwork) in AH was flown by 418 "City of Edmonton" Squadron, RCAF. 418 Sqd was the most successful Day Ranger squadron, but it is acurate that this aircraft had flame dampers even though it was primarily used during day time operations.
