The HAV 606 is the mid-size craft in a family of Hybrid Air Vehicles ranging up to 1,000 tonnes payload capacity. The vehicles derive their flight capability from a mix of aerodynamic lift and Helium buoyancy. Construction is based upon a series of current technologies brought together to form an evolutionary new mode of transport.


Laminated fabric construction hull with internal catenary system supporting the payload module. The hull’s aerodynamic shape, an elliptical cross-section allied to a cambered longitudinal shape, provides up to 40% of the vehicle’s lifting needs. The internal diaphragms required to support this shape allow for a limited amount of compartmentalisation further enhancing the fail-safe nature of the vehicle. Pressure control is provided by multiple ballonets located fore and aft in each of the hulls.

Landing System

Hover skirts on the underside of the two outer hulls provide an amphibious capability with an enhanced (compared to conventional airships) ground handling ability. Hover skirts are ‘sucked-in’ for a clean-in-flight profile and enhanced all-round visibility. System shares use of ballonet fans with hull pressure system.

Power Plant

4 x 8,000 shp (6,000 shp max. cont.) turboprop gas turbines. An engine within each stern duct drives a propeller. An engine is configured forward on either side of the hull also within a duct. The forward engines are for ground handling and take-off. All four ducts are configured with blown vanes to allow vectored thrust for take-off, landing and ground handling operation.

Payload Module

Located on centerline providing roll-on/roll-off freight capability. Primary features are as follows:

  • Flight deck forward on centerline above the forward cargo ramp.
  • Flight deck provides side-by-side pilot stations along with 200 ft2 of accommodation for off-duty crew members.
  • Main load deck provides clear space for cargo/freight on a military rated floor structure. Mezzanine decking can be provided to give multiple lower load area.
  • Rear cargo ramp provides roll-on/roll-off access to load deck. Above door aperture is a further 400 ft2 of accommodation space.

Flight Controls

Dual-channel, optically signalled, flight control system.
