D.Ford - Anglo-French Aspects. Cross Channel High Aspect Wing Development
HD-34 F-BHOO pictured in 1987. The KLM Cityhopper Fokker F.27 to the left provides a good comparison of scale.
The Series 3 Skyvan, with Garrett TPE331 turboprops was a much more developed airframe than the early SC.7 variants. This head-on aspect of a Ghana Air Force Series 3M shows the H-D concept of supplemental lift struts and stub wings for the undercarriage to advantage.
Prototype Short SC. 7 Skyvan in its Series 1A form, with Turbomeca Astazou II turboprops as envisaged for HDM.107 Caravan.
The Miles HDM.105 in flight, carrying its initial ‘trade-plate’ registration. The structure from the base of the engine to the undercarriage/main strut union served as a faired fuel tank.

Operated by the ‘Association des Mecaniciens et Pilotes d'Avions Anciens', the prototype HD-34 F-BHOO making a STOL approach to the grass airfield of La Ferte Alois in 1990 after having dropped a parachute team - note the open door underneath the port engine.
Hurel Dubois HD.34 survey aircraft, the only practical application of high aspect ratio thinking in France.
The high aspect ratio wing needs distance to be appreciated! HD-34 F-BHOO also demonstrating its three landing lights and offset nose wheel.
A good view of the starboard main and auxiliary struts. It can be seen that the main strut has an appreciable chord, being a supplemental wing. The small pylon is carrying an air sampling pod.
Hurel-Dubois HD-31 in initial form with twin fins and rudders. Also side-view of the proposed HD-45 jet airliner.
Loganair Shorts 360 on take-off from the beech airstrip at Barra. The ‘360 is a modern day approach to Maurice Hurel’s quest for an economic regional airliner.
