Classic Light Aircraft- The Bellanca Skyrocket II

By Willie Bodenstein



The Bellanca 19-25 Skyrocket II, designed by August Bellanca, the son of the legendary Guiseppe Bellanca, was a six-seat, low-wing cantilever monoplane of conventional configuration with retractable tricycle undercarriage. It was constructed of composite materials, an advanced feature for its time and in test flying, proved to be extremely fast.

Within months of its first flight, the prototype claimed five world airspeed records for an aircraft in its class. The aircraft attracted the attention of NASA, which conducted an aerodynamic analysis of the design, in order to investigate natural laminar flow as a factor of its high performance.

Despite its advanced design and exceptionally good performance, it, due to the downturn in the civil aviation market in the United States in the early 1980s, never achieved certification or entered production.

In the mid-1990s, the design was developed into a kit and sold as the Skyrocket III to help fund a new certification programme. The Skyrocket III features greater speed, payload and range and was re-engineered for modular construction.
