A hybrid airship is an aircraft that combines characteristics of heavier-than-air (HTA) technology, fixed-wing aircraft or helicopter, and lighter-than-air (LTA), aerostat technology. Examples include helicopter/airship hybrids intended for heavy lift applications and dynamic lift airships intended for long-range cruising. No production vehicles have been built, but several manned and unmanned prototypes have flown and successfully demonstrated the concept.
The term "hybrid airship" has also been used to describe an airship combining elements of different types of airships.
