Summary

The HAV 266 is the smallest 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.

Envelope

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 lift. The internal diaphragms required to support this shape allow for a limited amount of compartmentalisation further enhancing the fail-safe nature of the vehicle. Multiple ballonets located fore and aft in each of the hulls provide pressure control.

Landing System

Hover skirts on the underside of the two outer hulls provide an amphibious capability with an enhanced 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 750 hp (600 hp max. cont.) horizontally opposed, two-stroke, direct injection, diesel engines. Supercharged induction system. Two engines mounted forward on the hull and two on the stern of the hull for cruise operation. All four are configured in ducts with blown vanes to allow vectored thrust for take off/landing/ground handling operation.

Payload Module

Located on centerline (the larger vehicles In the range provide roll-on/roll-off freight capability). Comprises 3 primary areas as follows:

Flight Deck:

  • 2 pilot stations.
  • Twin sidestick controls.
  • Large transparencies for excellent all-round visibility.

Mid-body:

  • Payload compartment.
  • Two large side access doors with built-in steps. 6 seat-tracks for flexible location of equipment and seating.

Aft-body:

  • Full width door and integral ramp for cargo use.

Flight Controls

Dual-channel, optically signaled,flight control system.
