Globe KD5G

The Globe KD5G is a pulsejet-powered American target drone produced by Globe Aircraft Corporation that began development in 1949. Due to changing requirements for drone performance, it was only operated by the United States Navy for a short period.

Design and development

The XKD5G-1 was of conventional high-wing, twin-tail design, a Marquardt PJ46 pulsejet being mounted externally atop the fuselage, in the same style as the World War II German V-1;[1] it was one of the last aircraft produced for the U.S. military to be powered by a pulsejet.[2] The KD5G had a top speed of 345 miles per hour (555 km/h); if it was not shot down during its mission, it could be recovered by parachute to be flown again.[2]

Operational history

Originating in 1949, the XK5DG-1 first flew in 1950,[1] and was tested at the Naval Air Test Center in Point Mugu, California. By 1952, however, the speed requirements for target drones had increased to the point that the KD5G was considered too slow for operational service, while pulsejets also lost efficiency quickly at higher altitudes; as a result the XK5G-1 project was cancelled.[2]

Surviving aircraft

A surviving XKD5G-1 was donated to the National Air and Space Museum by the U.S. Navy in 1966; it is displayed in the Steven F. Udvar-Hazy Center.[2]

gollark: > The interpretation of any value was determined by the operators used to process the values. (For example, + added two values together, treating them as integers; ! indirected through a value, effectively treating it as a pointer.) In order for this to work, the implementation provided no type checking. Hungarian notation was developed to help programmers avoid inadvertent type errors.[citation needed] This is *just* like Sinth's idea of Unsafe.
gollark: > The language is unusual in having only one data type: a word, a fixed number of bits, usually chosen to align with the architecture's machine word and of adequate capacity to represent any valid storage address. For many machines of the time, this data type was a 16-bit word. This choice later proved to be a significant problem when BCPL was used on machines in which the smallest addressable item was not a word but a byte or on machines with larger word sizes such as 32-bit or 64-bit.[citation needed]
gollark: SOME people call it Basic Combined Programming Language.
gollark: Bee Control Programming Language is VERY cool!
