The Grigorovich MK-1 (MK - Morskoi Kreiser - sea cruiser) was a large trimotor floatplane, built and tested in Imperial Russia in 1916.

Design and development

Grigorovich responded to a requirement for a reconnaissance-bomber, for use in the Baltic Sea and Black Sea, issued by the Imperial Russian Navy central headquarters. The resulting large seaplane following the layout of the Sikorsky Ilya Muromets, with a large glazed cabin sitting atop a long slender fuselage. The fuselage and large wings were mounted on a large central float, which also housed a large gunners cockpit housing two gunners. The wings, mounted with flexible bungee joints allowing up to 180 mm (7.1 in) of movement, also carried wing-tip floats for stability on the water. Two 220 hp (160 kW) Renault 12E V-12 water-cooled engines were mounted in strut-supported nacelles between the upper and lower mainplanes. A third engine was added to the centre section of the upper mainplane, to address perceived centre-of-gravity problems and increase the power available; initially this was to have been a 150 hp (110 kW) Sunbeam Crusader, later replaced by a 140 hp (100 kW) Hispano-Suiza 8A before flight trials commenced.

The sole MK-1 was readied for flight trials in mid-November 1916 but nosed over and sank during taxy trials before the first flight. [1]

Grigorovich M-16 was a successful Russian World War I-era biplane flying boat of the Farman type, developed from the M-9 by Grigorovich. Somewhat larger than the M-9, the M-16 was a version especially intended for winter operations, with better aerodynamic qualities.

Polikarpov DI-1 Soviet aircraft

Polikarpov DI-1, also known as 2I-N1, Russian: Поликарпов ДИ-1 (2И-Н1), was a prototype Soviet two-seat fighter designed during the 1920s. The sole prototype built crashed on its ninth flight, due to manufacturing defects, and the program was cancelled.

Grigorovich DI-3 Type of aircraft

Grigorovich DI-3, , was a prototype two-seat fighter developed in the Soviet Union in the 1930s. It was intended to be a long-range escort fighter developed from the DI-2 with improved range and performance comparable to single-seat fighter aircraft of the time. DI-3 was a single-bay biplane of mixed construction with a twin-rudder tailplane of variable incidence. Although initial tests demonstrated flight characteristics comparable to Polikarpov I-5, the addition of armament and operational equipment caused significant degradation in performance and DI-3 did not enter mass production. The prototype was subsequently fitted with an enclosed cockpit and used as a VIP transport.

Anatra Anadis Type of aircraft

The Anatra Anadis was developed in 1916 as a single-seat fighter variant of the Anatra Anasal reconnaissance biplane. The main difference between the two aircraft was the streamlined fuselage, the lack of a rear seat in the Anadis, plans for a forward-firing gun and a different engine.

The Vickers F.B.24 was a British two-seat fighter aircraft of the First World War. Only a few prototypes were built, as, although it had good performance, the Bristol F.2 Fighter was preferred.

Nieuport-Delage NiD 37 Type of aircraft

The Nieuport-Delage NiD 37 was a single-engine, single-seat monoplane fighter aircraft and racer designed and built in France in the early 1920s. It had a small foreplane to bring the centre of pressure forward. Heavy, slower than expected and with turbo-supercharger problems, development ended without any entering service.

Les Mureaux 3 Type of aircraft

The Les Mureaux 3 C.2 and Les Mureaux 4 C.2 were French two seat, parasol winged fighters, flown in 1927-8, which differed only in their engines. They were developed into near identical army co-operation types, the ANF Les Mureaux 130 A.2 and ANF Les Mureaux 131 A.2, in 1929-31.

The Nieuport-Delage NiD 450 was a French racing floatplane, originally intended to compete for the 1929 Schneider Trophy. After the French decided not to participate that year, the type was used as the NiD 650 to speed the development of the proposed entrants to the 1931 event, the NiD 651 and NiD 652. Delays in producing the latters' engines left these unflown.

The Blériot 71 was a large First World War French heavy night bomber designed and built by Blériot to the BN3 specification. Only a single prototype was built, which was damaged beyond repair on 15 May 1918.

The Blériot 73 was a large First World War French heavy night bomber designed and built by Blériot to the BN3 specification. Only a single prototype was built, which crashed on landing from its first flight, killing the pilot. The Blériot 74, Blériot 75 and Blériot 76, respectively, a heavy bomber / airliner, airliner and heavy bomber, directly evolved mfrom the Blériot 71 / Blériot 73 bombers.
