Top Speed: P-47D vs P-51D

Recommended Posts

There seems to be Less than expected Consensus (and no Standardized Methodology for Measuring) on the Top Speeds of WWII Fighters.

 

I decided to see what I could get out of the DCS World P-51D and P-47D.

 

Using Instant Action - Caucasus - Free Flight - Missions

and

Clean Configuration - Prop Fine Pitch - Full Throttle - After Leveling Off at Test Altitude, allowed Three Minutes for Aircraft to Accelerate and Stabilize at Steady State Speed

 

Here’s what I got:

 

Ft MSL Type P-47D P-51D

 

5,000 mph 322 343

KIAS 280 298

 

15,000 mph 297 293

KIAS 258 255

 

25,000 mph 251 261

KIAS 218 227

 

NOTE: Formatting of Pasted Text got Jumbled - Please See attached Picture of Comparison Chart - Tanks !

 

Result Summary: The Mustang certainly hold a Speed Advantage at Low Altitude, while at Higher Altitudes the Two Aircraft are fairly Close

 

Interested in anyone else's Results :pilotfly:

Top Speed of a D-30 IRL. at 64" WEP

 

SL: 345mph (555kph)

5,000: 370mph (595kph)

15,000: 404mph (650kph)

24,500: 437mph (703kph)

29,000ft: 443mph (712kph)

 

Once the P-47 is finished we should see speeds very close to this.

 

What prop this data is for?

What prop this data is for?

 

Curtis Electric Blade 836-2C2-18. Pretty much the standard paddle prop on all P-47s (except for the D-22, D-25, and D-27. They used the Hamilton)

D-23, D-26,D-28, and D-30 all used the Curtis prop.

 

I should clarify that the speeds below 29,000ft were achieved at a design useful load of 13,020 lbs.

 

The Speed at 29,000ft was at a weight of around 12,700 lbs. From other documents I've seen at 13,000lbs it would be closer to 436mph at 29,000ft.

Weight is not a significant factor for max speed as it is a high powered plane.

MP? P-51 with 67" MP can reach at SL 368 mph TAS. At 5000ft 385-390 mph.

Conditions - ISA. Manual radiator control to stay within temp limits.

My Speed were Indicated (Not TAS)

At 5,000 ft MSL I got 343 (Indicated) mph out of the 'Stang' in Level Flight Full Throttle. Corrected to TAS (ROT 2% for every 1,000 ft in Altitude), that 343 mph Indicated would equal approx 380 mph TAS.

Very Close to what you Experienced :pilotfly: !

2% for every 1000ft is not reliable. Why not just look at your TAS with the tools available to you in DCS?
