"The sheer number of airframe repairs required after the hailstorm provided five years' worth of experience for the airframe mechanics," Regional Command South, the coalition headquarters based in Kandahar, said in a news release about the repairs.
the number of airframe reworks, aircraft engine reworks, and vehicle overhauls which should be performed by the Army, Navy, Air Force, and Marine Corps during the next fiscal year.
All three of the airframe proposals shared a number of features.
In the absence of an official two-seater variant, a number of airframes were crudely converted in the field.
The A330 was developed in parallel with the four-engine A340, which shared many common airframe components but differed in number of engines.
It has evolved from experience in airframe manufacture, which found that the number of man-hours spent in building a plane declined at a regular rate over a wide range of production.
That is bad — and to make matters worse, military airframe wear and tear is increasing for a number of other reasons.
A number of cabin experience benefits carry-over from the airframe manufacturer's latest-generation commercial planes, including lower cabin altitude.
The Spitfire's airframe was complex: the streamlined, semi-monocoque duralumin fuselage featured a large number of compound curves built up from a skeleton of 19 formers, also known as frames, starting from frame number one, immediately behind the propeller unit, to the tail unit attachment frame.
In the postwar era, the idea was revived by Supermarine and a number of two-seat Spitfires were built by converting old Mk IX airframes with a second "raised" cockpit featuring a bubble canopy.
