Serial numbers

edit

Apparently there is a discrepancy as to the serial numbers that exist at the Army Aviation Museum at Fort Rucker, Alabama. Or just the numbers that exist on the aircraft in particular. The numbers in the article are straight off of the Army Aviation Museum's collection list, although I will write them and request clarification, since the serial group the Army started off with is 15 not 51, and is now around 26 or 27. This would seem to lend itself to the smaller number in many pictures, which if the Army's serial number pattern holds should be 15262 or 15263. If the number really is 51 instead of 15, that my be an acknowledgment of the aircraft's X-number and to distinguish it from any similar serial numbers acquired during the same year. As it is, there are several different versions of what the serial numbers of the aircraft should be rather than any definitive proof as to what they are. However, I hold that the owner of the two aircraft in question is probably slightly more reliable than anecdotal references, even in printed references, that seem to disagree with each other. --Born2flie 17:53, 2 September 2007 (UTC)Reply

No images and very little documentation. Originally Lockheed production Model 86, it was the Model 186 (1st development of the base model) that ultimately became the XH-51A and XH-51A Compound. The aircraft were procured for a joint Army-Navy program testing high-speed helicopter flight with the rigid-rotor design. The Army also conducted an evaluation to determine the effect of speed on an enemy's ability to acquire and target helicopters. The study's conclusion was that a compound helicopter was much more survivable than a conventional helicopter. This study became a factor in the Army's decision to make the AAFSS requirement for a compound helicopter.

The subsequent development of the helicopter, Model 286 was certified with the FAA and an attempt was made to market it to the civilian market. One model 286 crashed during a test flight according to the NTSB's accident database.

This aircraft was also designated as design CL-595,[1] the "CL" indicating the model was a Lockheed design from the Van Nuys, California Lockheed plant. --Born2flie 05:10, 29 November 2006 (UTC)Reply
