The Cameron D-38 is a single seat hot air filled airship, designed and built in the United Kingdom in 1980.
Its prototype began life and was flown as a hot air kite balloon, which was to have been marketed as the C-38, the -38 stating the envelope volume in thousands of cubic feet.
A 250 cc Fuji Robin two-stroke engine, driving a semi-shrouded two blade propeller, is attached to the rear of the gondola.
[1] Tests of the D-38 showed it was not large enough to cope with hot and high environments, so a version with an envelope linearly enlarged by 9.4% and a volume of 50,000 cu ft (1,416 m³) was produced, designated the D-50.
[4] On 27 August 1982 Ron Taafe in Australia set a series of FAI recognized records for BX class dirigibles in a D-38: altitude, 10,364 ft (3,159 m); distance, 23.03 mi (37.07 km) and duration, 86 mim 52 s.[1] Eleven D-50s had been built by the start of 1984.
