If not the Dewoitine D.500, or any of its variants, why not the plane it beat out in the competition; the Bernard 260 C1? Thanks; Ernie P.


The Bernard 260 C1 was a French all metal, single engine, low wing monoplane with an open cockpit and fixed undercarriage, designed to a government single seat fighter specification issued in 1930. After extensive comparative tests the Dewoitine D.500 was ordered in preference, though the performances of the two aircraft were similar.

The Bernard 260 C1 (C for Chasse or fighter, 1 stating single seat) was the last of a long line of Bernard fighters to fly. It was built, along with about nine different designs from other manufacturers, to a 1930 government C1 specification calling for a maximum speeds of 325 km/h (202 mph) at 3,500 m (11,480 ft) and 300 km/h (186 mph) at 6,000 m (1,970 ft). Landing speeds had to be less than 100 km/h (62 mph). In 1931 it further specified an increased specific static strength and raised all speeds by 25 km/h (16 mph) if a supercharger was fitted. A final amendment, made in 1932, was that supercharging was obligatory and that the fighter should be armed with four machine guns or two cannons or one cannon with two machine guns.

The 260 was the most advanced aircraft of the group of prototypes, equipped with almost full span Handley Page slots as well as flaps on its low cantilever wing. The wing plan was straight edge and square tipped, with most of the taper on the trailing edge, its whole span occupied by ailerons and flaps which could be lowered together. The wing had a duralumin structure with a riveted metal skin. The tail surfaces had swept, almost straight leading edges, rounded tips and unswept trailing edges on the unbalanced control surfaces. The fuselage was built from two metal half-ovals joined vertically, with a riveted skin. The open cockpit was placed at the wing trailing edge, the fuselage tapering behind it. Each wheel of the 260's fixed, tailwheel undercarriage was mounted on a vertical, faired main leg, with a second strut behind forming a V and a third inboard to the fuselage underside. At the time of the first flight the wheels were enclosed in fairings but these had been removed by October 1932. Two cannons were fitted to the wing undersides, firing outside the propeller arc.

The Bernard 260 was powered by a 515 kW (690 hp) Hispano-Suiza 12Xbrs liquid cooled upright V-12 engine. Several different radiator arrangements were tried. For the first flight, made by Roger Baptiste in September 1932, a boxed chin radiator was used but was soon replaced by a pair of vertical units attached to the undercarriage legs. By November these had been replaced with a curved, open radiator under the engine, followed by yet another unsatisfactory system in January 1933. In March a retractable Villard-Ferlay radiator was fitted; this was used in the competitive tests.

In March 1933 the 260 was fitted with a sliding glass canopy, but the military feared the rear view would be lost and it was quickly removed. The height of the fin was increased to improve stall recovery. In June the slats were modified to open automatically. After losing its propeller in flight in July the 260, which landed safely, was significantly modified. The span was reduced by 1.25 m (4 ft 1 in) and a final radiator change was made. This involved an almost circular unit in front of the engine, with the propeller shaft emerging through it, above the centre. As a result the profile of the nose was considerably altered, appearing less streamlined. At about the same time, the 260 regained its wheel fairings. It first flew in this form on 4 October 1933.

The Bernard 260 flew for more than 100 hours and made several hundred takeoffs and landings at the military test centre at Villacoublay but, in the end, no contract was awarded. Instead, the Dewoitine D.500 was put into production. Bernard were told that the reasons they failed were the difficulties encountered with the cooling system, the weight penalty of the slots and the difficulty of deploying them in manoeuvres and the lower rate of climb, the 260 taking about 10% longer to reach 3,000 m (9,840 m) than the Dewoitine. They were also concerned by the "chaotic" state of Bernard's management structure. Which of the two aircraft was faster in level flight depended on altitude; the Bernard was faster at height down to less than 5,000 m (16,400 ft), for example by 9 km/h (5.6 mph) at 6,500 m (21,325 ft) but at sea level the Dewoitine was quicker by 6 km/h (3.7 mph). The Bernard could take off in 140 m (460 ft) and land in 180 m (590 ft).

The end of the 260 programme also finished two proposed developments: the 261, which would have had the more powerful, 642 kW (860 hp), Hispano-Suiza 12Ybrs and a retractable undercarriage and the 262, a carrier-borne fighter with arrestor hook etc. Only the 261 reached the construction stage.

I wonder if the definition of "single seat" could be stretched to include an aircraft with one seat and a bed for a reserve pilot? Thanks; Ernie P.


The Fairey Long-range Monoplanes were a pair of British experimental aircraft of the late-1920s and early 1930s. They were single-engine, high-wing aircraft with fixed tail skid landing gear.

The first aircraft was designed to meet Air Ministry Specification 33/27; it was issued by the Directorate of Technical Development (DTD) in December 1927 after the failure of three attempts by the RAF to break the absolute distance world record flying Hawker Horsley bombers. According to a Ministry spokesman in the House of Commons, this aircraft was to be constructed not just "for a specific record," but as a serious study into methods of increasing the range of aircraft. In order to soothe the anxieties of the Treasury, the aircraft started life as the Postal Aircraft. The sharp, pointed nose and sleek lines of the prototype gave rise to the nickname "Eversharp," after the maker of pens and mechanical pencils.

Although other configurations were studied, after wind tunnel testing, a high wing was chosen, allowing a gravity feed from the fuel tanks. The wing spars were of wood and the wing used a pyramid system of internal bracing with fabric covering. The fuel capacity was 1,043 Imp gals (4,742 L) and the system used a gravity feed and mechanical fuel pump in sequence; a wind-driven, emergency back-up pump was also provided. There were other features dedicated to the long-range function; there were two parallel oil filter circuits, allowing one filter to be removed and cleaned while the other remained in operation. The aircraft was even equipped with a pneumatic bed for a reserve pilot. After extensive testing using a Fairey IIIF and a DH.9A, the Napier Lion XIA of 570 hp (430 kW) was selected, late in the gestation of the machine.

The first built, J9479, flew for the first time on 14 November 1928 from RAF Northolt. The aircraft was handed over to the RAF on 7 December, and with testing continuing in preparation for the record attempt, including a 24-hour trial on 22-23 March 1929. It was decided to attempt a flight to Bangalore in India, a Great-circle distance of about 5,000 mile (8,000 km), comfortably in excess of the existing record of 4,466 miles (7,188 km) set by a Savoia-Marchetti S.64 in July 1928. Squadron Leader A G Jones-Williams and Flight Lieutenant N H Jenkins set off on the record attempt from RAF Cranwell, Lincolnshire on 24 April 1929. The aircraft was slowed by headwinds, however, and the plane landed at Karachi after 50 hours 48 minutes in the air. Although the flight was the first non-stop flight between Britain and India, the great circle distance of 4,130 miles (6,646 km was short of the world records. It was decided to make another record attempt later that year, although the record had been raised to 4,912 miles (8,007 km) by the Breguet 19 Point d'Interrogation. This time it was planned to fly to from England to South Africa. This second attempt, with the same crew as the first, took off on 16 December 1929, but crashed south of Tunis, destroying the aircraft and killing the crew.

Despite this setback, the Air Ministry ordered a second Long-range Monoplane (K1991) in July 1930, this flying on 30 June 1931. While similar to the first aircraft, it had a number of differences, including the addition of an autopilot.


Gayford and Nicholetts with Lord Londonderry and Sir John Salmond

From 6-8 February 1933, Squadron Leader O Gayford (officer in charge of the RAF Long Range Development Unit) and his navigator Flight Lieutenant G.E. Nicholetts flew non-stop in the second aircraft K1991 from Cranwell to Walvis Bay, South West Africa. This was a world long-distance record of 5,410 mi (8,540 km). On their return to RAE Farnborough, they were met by the Air Minister (Lord Londonderry), Under Secretary for Air (Sir Philip Sassoon) and Sir John Salmond, Marshal of the Royal Air Force.

Gayford and the LRDU would later make long distance flights with the Vickers Wellesley.
