40-495: A four bladed, 9 ft 3 in (2.82 m) diameter propeller and was partly enclosed in a metal cowling, with the cylinder heads protruding as it was air-cooled. There was a simple single axle undercarriage and tail skid. The date of the first flight is not known, but it was probably towards the end of 1918. The first drawings were dated April 1918 and the aircraft was certainly beyond its initial flight tests in March 1919 when it provided
60-528: A pair of vee struts to front and rear spars, assisted by another strut from front spar to the engine bulkhead The wings were built around two I section spars, each a box section constructed from rolled strips. The forward spar had four of these strips, the rear two. The P.10 was displayed at the Paris Salon d'Aeronautique in 1919 without its fabric covering, the wing construction was in plain view. There were interconnected ailerons on both wings. The P.10 had
80-488: A rather distant second cockpit under the trailing edge, about 5 ft 6 in (1.68 m) aft. Dual control was fitted. As exhibited in Paris, the P.10 had a tall single axle undercarriage mounted on a pair of vee-struts on either side. These were bungee sprung, though there were plans for oleo dampers. The P.10 was not the first metal British aircraft, for the unlikely looking Seddon Mayfly holds that priority; but it never had
100-466: A realistic hope of flight. One lesser novelty, which was to become a standard Boulton & Paul feature was the mounting of the Lucifer on a hinge so that it could be swung sideways for servicing without disconnecting pipework etc. The P.10 made a big impact at the 1919 Paris show, with Flight describing it as "the machine of the show". Nonetheless, after the show the P.10 disappeared from sight. There

140-413: A small fin, which with its horn balanced rudder formed a teardrop shape. The tail, with unbalanced elevators was strut braced to the fin. The front fuselage was built on four tubular longerons, but from leading edge rearwards it consisted of a set of oval formers with stringers. The greatest novelty of the P.10 was that this part of the fuselage was not only a monocoque structure (still fairly unusual at

It is also notable for its first use of plastic as a structural material. Only one P.10 was built and it attracted much attention; but it probably never flew. In
180-514: Is no record of it flying, though there seems no reason why it should not have been capable. There are reports of it being damaged when the engine failed. It was not at the Paris show of 1920. Surprisingly, the delicate structures of one wing and the fin and rudder assembly have survived. The fin and rudder are at the Bridewell Museum in Boulton & Paul's home town of Norwich. The wing section

#1732845080327240-502: The first decade of the 20th century, Boulton and Paul besides their wood construction shops also had plants for iron making, wire fencing and structural steel for buildings. It is not surprising therefore that when they became involved with aircraft production in World War I and then began their own designs they soon looked to the use of steel airframes. The Boulton & Paul P.10 was the first example and only their third design. The P.10
260-421: The fuselage a smooth, rounded "torpedo-like" look, which was enhanced by the close cowling of the 100 hp (75 kW) Cosmos Lucifer radial engine, though its three cylinders projected out a long way for cooling. This engine drove a four bladed wooden propeller, the only wooden part of the airframe. Boulton Paul had made their own propellers during the war. The front cockpit was at the wing leading edge with
280-447: The large interplane gap, also 5 ft, would have helped to reduce the complications of interference effects. The initial section used was RAF15. There were ailerons on both upper and lower wings. The fuselage was flat sided with a rounded top, rather similar in construction to that of the Camel and using many Camel parts. The fin and horn balanced rudder together were almost circular and
300-416: The tailplane was braced to the fin. The large interplane gap put the upper wing well above the fuselage with the centre section braced to front and rear spars by outward sloping struts from the upper longerons. The pilot's cockpit was under the trailing edge, where there was a cut-out for visibility and the passenger sat in a separate cockpit under the wing. The 90 hp (67 kW) RAF 1a engine drove
320-424: The time), but a monocoque of steel with a load-bearing plastic skin riveted between the formers and stringers. Specifically, the plastic was Bakelite -Dilecto, a hard, synthetic cellulose-formaldehyde product. The company claimed it was proof against fire, heat, humidity and insects. This was the first use of structural plastic in an airframe and perhaps the last for another sixty years. This construction gave
340-498: The wife of Dawson Paul, one of the company directors, with her first flight. Though shortly after that the P.6 received the civil registration G-EACJ (K-120), it may well have never displayed this identity. In all known photographs it wears the experimental number X.25, the last one of this series inaugurated in 1917. In addition it was painted with RAF roundels and tail stripes. It is not known if wings of other sections were fitted as originally intended, but useful aerodynamic data
360-405: Was a single-engined two-seat biplane with an airframe of high tensile steel, zinc treated and varnished against corrosion. It had single bay wings with no stagger or sweep. Both wings had the same span and the same constant chord. Rather like the earlier P.6 , the interwing gap was large and equal to the chord, putting the upper wing high above the fuselage. Either side of the centre section were
380-434: Was gathered. It flew rather well and by May 1919 Boulton & Paul were using it as their sales machine, with the company name in large print on the fuselage side in addition to the roundels. This corporate aircraft made perhaps the first business flight, from Boulton & Paul's airfield on Mousehold Heath at Norwich to Bury St Edmunds about 36 miles (58 km) away. A replica of this aircraft has been built by
400-500: Was only the second aircraft designed and built by Boulton & Paul , although during the First World War they had built many aircraft under contract, including 1,575 Sopwith Camels . the P.6 was a wood and fabric two-seat single-engined single-bay biplane. Its wings were without stagger or sweep, with a constant chord of 5 ft (1.52 m) on both wings. The intention was to explore the effects of different airfoil sections and
