FLIGHT, NOVEMBER 17, 1932 British Aircraft at the Paris Aero Show The British Aircraft Industry promises to be well represented at the Thirteenth International Aero Exhibition to be held in the Grand Palais, Champs Elysees, Paris, from November 18 to December 4. Not only are several aircraft firms represented on stands in the actual exhibition, but others will have demonstration machines at le Bourget during the exhibition. British aero engine and aero accessories firms will also be well represented at the show, and altogether Great Britain can be said to be showing considerable enterprise in these very difficult times. This week we deal with the British aircraft to be exhibited in the Grand Palais. Next week we shall deal with the aero engine and aero accessories firms who are showing in Paris. Lfie Dnstol Aeroplane Co., Ltd. NO British aircraft firm has been a more frequent and consistent exhibitor at Paris Aero Shows than the Bristol Company. Scarcely an aero exhibition has been held in the Grand Palais but what Bristol aircraft have been there to uphold British prestige. It is therefore gratifying to find that again this year we shall see the familiar name " Bristol " on the banners flying above the stands. The exhibit on the aircraft stand (Bristols are also showing engines on a separate stand) will include a 1933 model " Bulldog " (Bristol Mercury IV S.2 engine) and specimens of Bristol types of metal construction. The 1933 model " Bulldog " is essentially a development of the " Bulldog HA," which is the standard single-seater fighter of the British Royal Air Force. All the improve ments which long experience of the earlier machine has suggested have been incorporated in next year's model. The most notable improvement is that associated with performance. By installing the more powerful Mercury IV S.2 instead of the Jupiter VII F advantage is taken of the smaller diameter of engine, while the extra power plays its part also. Secondly, by cowling the engine with a " Townend " drag-reducing ring, the performance is still further improved. The shape of the engine has made pos sible the installation of a new type of exhaust collector ring, which not only gives lower drag but actual] v improves the cooling. In place of double wing bracing wires the 1933 " Bull dog " has single wires of greater cross-sectional area, which again reduce drag and also vibration. By choosing a thicker wing section (R.A.F. 34 to be more explicit) it has been possible to house the petrol tanks entirely within the wing contour, thus again reduc ing drag. Another result of using this wing section is that it has been possible to reduce the chord of the lower wing slightly, thereby improving the view. Stiffer ailerons, mass-balanced, have been fitted on the new model, and each aileron hinge is self-aligning. The horn balance of the elevator has been increased in area, making the elevator lighter and smoother in operation. All these improvements have been carried out without introducing departures from the features of design found successful in the older model. THE BRISTOL " BULLDOG," 1933 MODEL : This is the aircraft which will be exhibited on the Bristol stand in Paris. 1064
