    well if anyone wants info or have questions about the engineering side of aircrafts specially engines, i would be more than glad to entertain them.

    further, not a big fan of the old AC. yeah they are cool, but not like the new AC. hav worked on most of the military AC in US and flown in sum of them, so ask anything, i'll try my best... chao.

    Hey Glad to See you on this thread.....:D....

    DO you know about Newest light Air Craft Engs..... Like Zlin..
    Few Months Ago In USA. I had flown a Charocke... But Its Sound was Very Different from normal.. The Owner Says that He Changed the Eng and Got the Newest one....

    In the Take off... I felt a huge difference of throttling.. But the Cockpit was Bit vibrating....

    And it was hard to control . The Nose Was Always Turing Down....

    Bristol Bulldog

    The Bristol Bulldog was a British Royal Air Force (RAF) single-seat biplane fighter designed during the 1920s by the Bristol Aeroplane Company, with over four hundred Bulldogs produced, that arguably became the most famous aircraft during the RAF's inter-war period.

    [img=http://img227.imageshack.us/img227/4165/300pxbristolbulldog1eu5.jpg]

    Design and development

    In September 1926, the Air Ministry stated a need for a single-seat fighter capable of operating in day and night-time conditions; to be armed with two 0.303 in (7.7 mm) Vickers machine guns and to be powered by a radial air-cooled engine. This requirement was laid down in Specification F9/26. The Bulldog was designed by Frank Barnwell, the Chief Designer of the Bristol company, (who had served as a Captain in the British Army during the First World War), as a private venture to meet the requirements of this specification. The prototype Bulldog, the Bulldog Mk. I first flew on 17 May 1927.[1] After initial consideration of all the types entered to meet the specification, the Bulldog and the Hawker Hawfinch were selected for more detailed evaluation.[1] While the Bulldog's manoeuvrability and strength were praised by the RAF,[2] it initially had poor spinning recovery properties and was therefore fitted with a lengthened rear fuselage. In this form, it was declared the winner of the competition, having slightly superior speed[2] and was easier to maintain,[2] and required fewer changes to produce an operational aircraft than the Hawfinch.[1]
    The full-production Bulldog came in the form of the Mk.II, which had a modified structure but in every other respect was identical to the original Bulldog; having two 0.303 in (7.7 mm) Vickers machine guns; a capacity for four 20 lb (9 kg) bombs; a 450 hp (336 kW) Bristol Jupiter radial engine; giving the Bulldog a maximum speed of just under 180 mph (290 km/h) and a range of 300 miles (480 km). The aircraft then entered production in 1928, entering service the following year, and becoming, during the early 1930s, the most widely used aircraft in the RAF. It was cheap to maintain and thus, at a time of defence budget constraints, was the more preferable option to any other competitors. The Mk. IIA was again virtually similar to its predecessor, though it had a new Jupiter engine and a strengthened structure.

    The Bulldog proved to be quite a successful export to foreign air forces, seeing service with Australia, Denmark, Estonia, Finland, Japan, Latvia, Siam, Spain and Sweden. The Bulldog was withdrawn from RAF service in 1937, being replaced by the Hawker Hurricane and Supermarine Spitfire, both of which would become legends of the RAF for their contributions during the Second World War. The Bristol Bulldog's career was not over though, for the type continued to serve with other air forces.


    Operational history

    The Bulldog never saw combat service with the RAF, though during the Abyssinia Crisis of 1935-36, Bristol Bulldogs were sent to the Sudan to reinforce Middle East Command. Douglas Bader, better known for his Second World War actions, lost both of his legs when his Bristol Bulldog crashed while he was performing unauthorised flying acrobatics. A number of Bulldogs, ex-Latvian aircraft, saw service during the Spanish Civil War, as part of the forces fighting the Nationalists. Nineteen Bulldogs also saw combat as part of the Finnish Air Force during the Winter War against the Soviet Union, which began in 1939. The Bulldogs fought well against their Soviet opponent, gaining six kills by five pilots for the loss of one of their own,[3] the types shot down being two Polikarpov I-16s and four Tupolev SB-2s,[3] both of which were quite superior in terms of technology compared to the Bulldog. In fact, the very first aerial victory of Finnish Air Force was achieved by a Bulldog piloted by SSgt Toivo Uuttu on 1 December 1939.[4] The Bulldog continued in service during the subsequent Continuation War against the Soviet Union, though without scoring any further kills or suffering losses.

    Supermarine Walrus

    walrus_m.jpg
    Catapult-launched, biplane amphibian with pusher propeller, developed from the Seagull. The Walrus was rather rectangular in outline, and did not show that it was built by the same manufacturer as the Spitfire. It was the standard catapult- launched reconnaissance and SAR (Search And Rescue) aircraft for some time. 740 were built between 1936 and 1944.
    General characteristics Walrus Mk. I Primary function Reconaissance / SAR Power plant One Bristol Pegasus VI radial engine Thrust 775 HP 578 kW Wingspan 45.8 ft 13.97 m Length 37.2 ft 11.35 m Height 15.3 ft 4.65 m Wingarea 610 sq ft 56.67 sq m Weight empty 4,900 lb 2,223 kg max. 7,200 lb 3,266 kg Speed 135 mph 217 km/h Ceiling 17,090 ft 5,210 m Range 600 mi 966 km Armament 2x .303 machine gun; 272 kg bombs Crew Three Date deployed 1935 Number built 740​

    Gayan,
    the thing about those AC are that they have countless available and cheap modifications in the market. specially engine wise. my guess is that the owner might have put a more powerful engine and hence having a bigger torque and weight than the AC is designed for. a lil tweak here and there could do the trick. but the vibration can be inherited by the engine. could be bad, if not taken seriously.
