Howard Wright Avis

Howard Wright designed and built helicopters, ornithopter, biplanes, and series of monoplanes, including five Avis.

Named “The Golden Plover” – and fitted with an Anzani three-cylinder delivering 25 to 30 hp – this wing-warping monoplane was delivered to the Scottish Aviation Syndicate in 1910.

The 1909 Howard Wright monoplane was designed and built by Howard T.Wright in the UK.

Wright Mk.I

Peter Wright started the construction of a man powered aircraft in January 1971 at Melton Mowbray, UK. Similar to the ‘Puffin’ but differing in having a three unit undercarriage and swept forward wings.

The Mk.I first flew in February 1972 for 120 yards. After several flights it was decided a better test site was needed and that a Mk.II should be built.

Wright WP-1

The sole Wright WP-1, A6748, was based on a Swiss-built Dornier Falke, imported by Wright Co. Built in 1923, it was all-metal, with an unbraced parasol wing, with a single-place open cockpit.

Wren Aircraft Wren

Single seat single engined high wing mono¬plane with conventional three axis control. Wing has swept back leading edge, swept forward trailing edge and tapering chord; conventional tail. Pitch control by elevator on tall; yaw control by fin mounted rudder; roll control by half span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile; double surface. Undercarriage has two wheels side by side with tailskid. Composite construction fuselage totally enclosed. Engine mounted below wing driving tractor propeller. Composite con¬struction with glass/Kevlar/graphite in an epoxy matrix over foam cores; fir, birch, plywood, pine and redwood also utilised.
The single seater Wren was a prototype in the course of test flying and whose development has been undertaken by Mark Calder since 1981. He has made his principal parameter passive security ‘crash survivability’. In January 1983, Mark Calder announced that he was going to undertake a programme of static tests on the machine, the prototype having made its first flight in the course of the previous year. The machine was to be offered with a Zenoah G25B engine or optionally a Kawasaki 440ce unit. Projected prices for the Zenoah engined machine were $6200 ready to fly and $4400 in kit form in 1983, the Kawasaki costing $300 more in each case. Options include wheel pants $100, custom interior $125, electric start $150 including battery, floats $1500, skis $100 and custom paintwork $250 minimum.
The prototype with Zenoah engine has returned a fuel consumption of 1 2 US gal/h (1.0 Imp gal/h, 3.8 litre/h).

Wren 460

In the late 1950s Jim Robertson designed the Skyshark featuring many STOL features. The best of these features was then applied to the Cessna 182G/H airframe to produce the Wren 460. These featured full span, double slotted flaps, moveable spoilers on the upper surface of each wing (called Wren’s teeth) to assist in roll control and a moveable high lift canard wing.

The Wren 460 first flew in 1958, and the 460 Beta STOL in 1968.

In August 1964 it was reported the Wren was building an initial production fleet of 10 Wren 460 STOL, two monthly. A second fleet of 40 was scheduled.

There were reported 34 conversions to Wren 460.

Wren Goldcrest

A small single-seat low-wing monoplane designed by R.E.Carr in 1946 and built by his Wren Aircraft Company in the UK.

Of all-wood construction and powered by a Scott Squirrel engine, registered G-AICX c/n 1, it first flew in 1947.

It found certification problems and was broken up in 1947.
