The Renard R.31 was a Belgian reconnaissance aircraft of the 1930s. A single-engined parasol monoplane, 32 R.31s were built for the Belgian Air Force, the survivors of which, although obsolete, remained in service when Nazi Germany invaded Belgium in 1940. The Renard R.31 was the only World War II operational military aircraft entirely designed and built in Belgium.

Design and development

The Renard R.31 was designed by Alfred Renard of Constructions Aéronautiques G. Renard to meet a requirement of the Belgian Air Force for a short ranged reconnaissance and army co-operation aircraft. It first flew from Evere Airfield, near Brussels, on 16 October 1932. [1]

It was a parasol monoplane of mixed construction, powered by a Rolls-Royce Kestrel engine, with a welded steel tubing structure with metal sheet covering the forward fuselage and fabric covering of the remainder of the airframe. The wing was held in position by a single Vee strut on each side, conjoined with its fixed under carriage.

An order for 28 R.31s was placed in March 1934, with six to be built by Renard and the remainder by SABCA. One aircraft was fitted with a Lorraine Petrel engine for evaluation, but this was later replaced by the normal Kestrel engine. A second aircraft was fitted with an enclosed canopy and a Gnome-Rhône Mistral Major radial engine, becoming the R-32, with this then being replaced by a Hispano-Suiza 12Y engine, but the R-32 did not show sufficiently improved performance to gain a production order. A further six R.31s were ordered in August 1935. [1]

Operational history

The R.31 entered service with the Belgian Air Force in 1935, [2] replacing the Breguet 19 in the 9e and 11eEscadrilles d'Observation based at Liège. In service, it was not popular, as it had poor handling, being vulnerable to entering flat spins if mishandled, with all aerobatics therefore being banned. [1]

The R.31 was hopelessly obsolete. Those that were not destroyed on the ground during the German Blitzkrieg invasion of Belgium in May 1940 were ravaged by German fighters as they attempted to gather information on the German invasion. None of the planes apparently functioned as ground support aircraft during the brief Belgian Army resistance, instead flying fifty-four reconnaissance sorties in support of the Allied forces defending Belgium. [2] The last sortie, flown on the afternoon of May 27, 1940, was also the final mission flown by the Belgian Air Force in its attempt to repel the Germans. [1] Following the German occupation of Belgium, the Luftwaffe had no interest in the machines, and those that had survived the initial onslaught were either unused or destroyed. Overall, these planes had no significant impact on the war, although they were briefly involved.

The Heinkel He 70 Blitz ("lightning") was a German mail plane and fast passenger monoplane aircraft of the 1930s designed by Heinkel Flugzeugwerke, which was later used as a bomber and for aerial reconnaissance. It had a brief commercial career before it was replaced by larger types. The He 70 had set eight world speed records by the beginning of 1933.

The Fairey Battle is a British single-engine light bomber that was designed and manufactured by the Fairey Aviation Company. It was developed during the mid-1930s for the Royal Air Force (RAF) as a monoplane successor to the Hawker Hart and Hind biplanes. The Battle was powered by the same high-performance Rolls-Royce Merlin piston engine that powered various contemporary British fighters such as the Hawker Hurricane and Supermarine Spitfire. As the Battle, with its three-man crew and bomb load, was much heavier than the fighters, it was therefore much slower. Though a great improvement over the aircraft that preceded it, its relatively slow speed, limited range and inadequate defensive armament of only two .303 (7.7 mm) machine guns left it highly vulnerable to enemy fighters and anti-aircraft fire.

The Henschel Hs 126 was a German two-seat reconnaissance and observation aircraft of World War II that was derived from the Henschel Hs 122. The pilot was seated in a protected cockpit under the parasol wing and the gunner in an open rear cockpit. The prototype aircraft frame was that of a Hs 122A fitted with a Junkers engine. The Hs 126 was well received for its good short takeoff and low-speed characteristics which were needed at the time. It was put into service for a few years, but was soon superseded by the general-purpose, STOL Fieseler Fi 156 Storch and the medium-range Focke-Wulf Fw 189 "flying eye".

The Hart was a prominent British aircraft in the inter-war period, but was obsolete and already side-lined for newer monoplane aircraft designs by the start of the Second World War, playing only minor roles in the conflict before being retired.
