The XP-51G was a development aircraft that combined the light weight airframe developed for the XP-51F with an experimental Rolls Royce RM-14SM engine, capable of producing 2,000hp at 20,000 feet. The new aircraft achieved a top speed of 495 mph, and a climb rate of 5,000 feet per minute, well over 1,000 feet per minute faster than the P-51D.

6 天之前 · They were the fourth and tenth production aircraft. One of them, 41-038, still exists today at the EAA Musuem in Oshkosh, WI. The Army was not in a big hurry to test the XP-51 seemingly bogged down in testing of other aircraft like the P-39, P-38 and P-47. Testing of the XP-51 began in October of 1941 with very high remarks.

In January of 1943, North American Aviation suggested to the USAAF that they build a special lightweight version of the Mustang. It was agreed that a thorough redesign would be carried out, mainly to reduce weight but also to simplify systems, improve maintenance, and enhance performance without changing the engine.

Designed in 1940 for use by Great Britain, the first prototype XP-51 was finished in just 117 days. The Allison-powered P-51A was dubbed the Mustang Mk. 1 by the British and first deployed in tactical reconnaissance in the spring of 1942. The U.S. Army’s Eighth Air Force received its first P-51s (B models) in 1943.

2025年3月10日 · NAA designed the XP-51G for lighter weight / higher performance. This is one of the light-weight P-51 prototypes. They never saw production. Story is that this airframe was on its way (literally) to the scrap yard in 1977, when the truck was stopped on the highway by a friend of John Morgan. Great story. This is a long-term restoration.

2011年4月15日 · Was it a completely new design, or derived from another, like those found on late Marks of the Spitfire? The five bladed one. The XP-51G was fitted with a Rolls-Royce manufactured Merlin RM.14.SM & one of the pair received a Rotol wooden 5 …

老生常谈的xp51g 比d马轻了将近1000磅，换RM14SM，2200批马力，进气压丧心病狂到120英寸汞柱（蚂蝗90英寸，ta152h80英寸）5叶螺旋桨，6900米能飞出792kmh，我本来以为这个发动机是换皮格里芬，结果没想到又是魔改梅林，虽然方案落选但是xp51f也就是蚂蝗用了大量xp51g的 ...

Interestingly, the aircraft, built as part of this "Lightweight Mustang", weighs comparable to the late Spitfire. By reducing fuel, you will be able to keep up with most reciprocating fighters in climing. However, on the other hand, be careful about landing. Wings for speed rationality have a negative effect on stall speed.
