The Avia B.158 was a prototype Czechoslovak twin-engined light bomber aircraft of the 1930s. Only a single example was built and it was abandoned, following the German occupation of Czechoslovakia in March 1939.

Development and design

In 1935, the Czech aircraft company Avia produced the B-58 design for a small twin-engined bomber with a fixed undercarriage, powered by two 313 kW (420 hp) Avia Rk.17 radial engines. This design was abandoned in 1936 and replaced by a more powerful and advanced derivative, the Avia B.158, which was designed to meet a requirement from the Czechoslovak Ministry of National Defense (MNO) for a high performance medium bomber, capable of operation during both day and night, and competing against Aero Vodochody's A.300. [1] [2]

In 1937, Avia started to build a single prototype of the B-158, a three-seat low-winged monoplane with inverted gull-wings, a retractable tailwheel undercarriage and 634 kW (850 hp) Avia (Hispano-Suiza) 12Ydrs engines, making its maiden flight in mid-1938. [2] It was fitted with a twin-tail to give a better field of fire for the dorsal gun position. [3]

While the competing Aero A.300 gave superior performance, neither had entered into production by the time Germany completed its conquest of Czechoslovakia. After testing by the Luftwaffe at their test centre at Rechlin, the prototype B-158 was scrapped in 1940. [1] [3]

The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520.

<span class="mw-page-title-main">Aero A.30</span> Type of aircraft

The Aero A.30 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia in the late 1920s. It originated as an attempt by Aero to improve the performance of the Aero A.11, but soon evolved into quite a different aircraft, larger and more powerful than its predecessor. The aircraft is readily distinguished from other related types by the difference in spans between its wings – the upper set being of much greater span than the lower.

<span class="mw-page-title-main">Aero A.100</span> Type of aircraft

The Aero A.100 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s. It was the final step in a design lineage that extended back to the Aero A.11 a decade earlier. A.100s remained in service throughout World War II and for a few years postwar.

The Aero A.104 was a parasol monoplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s. It was the final derivative of the Aero A.100, and was essentially an Aero Ab.101 with an enclosed cockpit and without the lower wing. Although two different prototypes flew in 1937, it was not mass-produced.

<span class="mw-page-title-main">Aero A.300</span> Type of aircraft

The Aero A.300 was a Czechoslovak bomber aircraft that first flew in 1938 as a much refined development of the A.304. It was designed by Aero to meet a requirement for a bomber-reconnaissance aircraft for the Czechoslovak Air Force, the Aero A-304 transport/bomber formed the basis for its design. It was a four-seat aircraft powered by two Bristol Mercury IX radial engines. The A-300 was faster than any other Czechoslovak aircraft in the inventory except for the Avia B-35 fighter. Despite showing much promise, development and production of the aircraft was stopped by the German occupation of Czechoslovakia.

The Tupolev ANT-40, also known by its service name Tupolev SB and development co-name TsAGI-40, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934. The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation".

<span class="mw-page-title-main">Avia B-34</span> Type of aircraft

The Avia B-34 was a biplane fighter aircraft built in Czechoslovakia in the early 1930s. It was the first design of František Novotný for the Avia company and although built only in small numbers, it paved the way for the Avia B-534.

<span class="mw-page-title-main">Avia BH-4</span> Type of aircraft

The Avia BH-4 was a prototype fighter aircraft built in Czechoslovakia in 1922. It was a development of the BH-3 fitted with a Hispano-Suiza 8 engine in an attempt to improve the aircraft's performance. To accommodate the new powerplant, the forward fuselage was considerably redesigned, and the structure in general and undercarriage in particular were strengthened. Performance was found to be only marginally better than the BH-3, and development was quickly abandoned.

The Levasseur PL.10 was a carrier-based reconnaissance aircraft developed in France in the late 1920s. It was a conventional, single-bay biplane along similar lines to Levasseur's contemporary designs for the French navy, including a watertight, boat-shaped fuselage, small underwing floats, and undercarriage that could be jettisoned in flight in order to improve the chances of a successful ditching.

The SNCAC NC.150 was a prototype French high-altitude bomber aircraft designed and flown just prior to the start of the Second World War. It was a twin-engined monoplane, with a third engine driving a supercharger. Although testing was promising, and orders were planned for a modified version as a back-up for the Lioré et Olivier LeO 45 and Amiot 354 bombers, the surrender of France in June 1940 ended development with only the single example being built.

The Adolphe Bernard AB was a twin-engined French biplane aircraft, built near the end of the First World War. Ten AB 1 BN2 bombers were produced for the Armée de l'Air but did not reach squadron service; post-war, two civil derivatives were considered but only one aircraft was built.
