Lacey M-10

Built by Joseph L Lacey in 1962, the the two place Lacey M-10 had a pivoting unbraced wing stowed fore-and-aft for trailing or hangaring. One was built, N73884, first flying on 7/6/62.

The Lacey is one of the simplest designs for the homebuilder to construct. In the words of its designer, “There are no com¬pound curves and very few simple ones. The wing has no wash-in, no washout, no dihedral, and no incidence angle (the bottom is flat, and fits flat on top of the fuselage). It has no taper, no slots, no flaps, no spoilers, no wingtips, no struts, no wires, no braces, no spars.” The two-place, towable Lacey is propelled by a 90-hp Continental.

One M-10 VW Twin was built, N187LH, in 1968.

Labahn Hitchiker

TerryLeave a comment

The Hitchiker is the third ultralight design from Robert Labahn and it is designed for cross-country and short field operations. With a rigid wooden wing sporting full span flaperons having both positive and negative selling, the light weight Hitchiker easily fits the bill. The pilot’s seating is reclining, glider like, to present the smallest possible frontal area. A streamlined pod will be fitted in the colder months for pilot protection.

Kyushu Q3W1 Nankai

TerryLeave a comment

The K11W served as the basis for the Q3W1 Nankai (南海, “South Sea”) anti-submarine patrol aircraft.

The Q3W1 retained the basic layout of the K11W2, with a circular fuselage and large wing with a straight trailing edge and tapered leading edge. It carried a crew of two with the remaining space allocated for anti-submarine warfare equipment. A single prototype was produced, and made its maiden flight in January 1945. This first flight ended with a wheels-up landing, and after that work on the project was suspended and didn’t resume before the end of the war.

Kyushu K11W Shiragiku / White Crysanthemum

TerryLeave a comment

The Kyūshū K11W Shiragiku (白菊, “White Chrysanthemum”) made by the Kyūshū Aircraft Company, was a land-based bombing trainer aircraft which served in the Imperial Japanese Navy Air Service in the latter years of World War II. As indicated by its Japanese designation, “training aircraft for on-board work” (機上作業練習機, kijō sagyō renshū-ki), it was designed to train crews in operating equipment for bombing, navigation, and communication, as well as navigation techniques.

The Kyūshū K11W had a mid-wing layout, the crew consisting of a pilot and gunner/radio operator sitting in line under the canopy and the trainee bombardier, trainee navigator, and instructor in the lower fuselage beneath the wing.

The K11W1 was a basic bomber crew trainer, of all-metal construction with fabric-covered control surfaces.

The K11W2 was a anti-submarine warfare and transport version of all-wood construction.

A total of 798 K11Ws were manufactured, including a small number of K11W2 ASW and transport aircraft alongside the K11W1 trainer variant. These aircraft were also used in kamikaze mission during the last stages of the Pacific War.

The K11W served as the basis for the Q3W1 Nankai (南海, “South Sea”) anti-submarine patrol aircraft.

Kyushu Q1W1 Tokai / Eastern Sea

TerryLeave a comment

Built as an anti-submarine patrol aircraft for home defense, the Q1W1 was mentioned in a Japanese Navy delivery schedule directed to the manufacturer that was captured in 1944 and received the allied code name ‘Lorna’. It wasn’t spotted in action until 1945.

Kyushi built 153 of the Q1W1 Tokai during the war (allied codename Lorna).

Some Tokais were equipped with crude forms of radar and submarine detection gear.

Kyushu J7W Shinden

TerryLeave a comment
J7W1

Towards the end of World War II the Japanese developed a canard fighter design which was the only such aircraft ever ordered into mass production. The machine was conceived in 1943 by Captain Masaoki Tsuruno, an Imperial Japanese Navy technical officer, who planned a jet powered high performance interceptor to counter the growing effectiveness of American air power in the Pacific. Three glider prototypes were built by the Dai lchi Kaigun Koku Gijitsusho (First Naval Air Technical Arsenal). They performed well, so in 1944 the Kyushu Hikoki company was commissioned to finalize the interceptor design. The Kyushu J7W Shinden (Magnificent Lightning) was powered by the 2130 hp Mitsubishi MK9D radial engine mounted amidships driving a six bladed pusher propeller through a long transmission shaft. It was armed with four 30 mm cannon and a projected maximum speed 0f 750 kph (466 mph) and a maximum operating altitude 0f 12,000 m (39,370 ft). The Japanese Navy ordered the Shinden into mass production long before the first prototype was ready. Nakajinia and Kyushu tooled up for but the first prototype did not fly until 3 August 1945, 12 days before the Japanese surrender.

Kysor 1950 monoplane

TerryLeave a comment

Cliff Kysor’s torpedo-shaped plane of 1950 had tail controls built flush with fuselage. The conventional elevators and rudder were eliminated to minimize air drag and permit greater speed. The four control surfaces at the top, bottom and sides of the tail section, were operated by a stick and by rudder pedals. Small tabs at the trailing edge of the fins were used only to trim the aircraft.

K+W Häfeli DH-5

Häfeli DH-5

The Häfeli DH-5 was a two-seat reconnaissance aircraft designed by August Häfeli. It was a single-bay biplane of wood and fabric construction. The aircraft was powered by a 180 hp (134 kW) LFW I engine produced by the Swiss Locomotive and Machine Works.

Built by the aircraft department of the Federal Construction Works (Eidgenoessische Konstruktionswerkstaette, K + W) at Thun, Switzerland, test flying of the prototype commenced in March 1919 and 39 were ordered. Some aircraft were later modified with Handley Page slats.

A second batch of 20 aircraft were powered by a 200 hp (149 kW) LFW II engine. A further batch of 20 aircraft designated the DH-5A used the LFW III engine.

The DH-5 entered service in 1922 with the Swiss Air Force and was not withdrawn from service until 1940.

Variants
