SOLYMPIA WITH this issue we conclude our detailed report of the Aero Show at Olympia, taking the machines first, followed by the engines. Following this report during the coming weeks we propose dealing in more detail with various exhibits which the pressure in the Show numbers has necessarily so far prevented. THE EXHIBITS.-(tt>/it//i!/etf.) BLACKBURN (THE BLACKBURN AEROPLANE CO.). THE monoplane exhibited by the Blackburn Aeroplane Co. is very similar to the machine sold to Dr. Christie, and fully described in our issue of December 27th, 1913. In the nachine shown, no attempt has been made to piovide a very showy finish, but it is a thoroughly sound piece of work, and although it is by no means a particularly heavy machine, it gives the impression of being very strong. Constructionally it follows fairly closely standard Blackburn practice, but the lines are now much more pleasing than were those of the twlier machines, and several detail improvements have been effected. The bearers fot the engine—an So h.p. Gnome—have been modified, and the result is a much neater nose to the machine, whilst the engine bearers »re probably as strong as were the old ones and certainly a good deal lighter. As belore, the engine is mounted between double bearings, but the front bearer is foinied in this machine by a horizontal U of channel tteel continued along the lr< nt portion of the longerons. The engir.e is partly covered in by an aluminium .shield, which prevents any oil from being blown back in the pilot's face. The triangular section fuselage has l>een retained, and is built up of 1 hree longerons of ash and spruce with struts of the same material, whilst diagonal stiips of wocd fotming a girder take the place of the usual internal cross wiring. The pilot is accommodated in a very roomy and comfortable cockpit, and in fiont of him i-i the passenger's seat, in a separate cockpit. The old type Blackburn contiol has been replaced by one of a more standard type, consisting of a roiatable band wheel mounted on veitical column, which actuates the warp and elevator. The rudder is operated by a pivoted foot-bar. The chassis consists of two stout ash skids supported on four vertical struts of the same material, and connected by two stream line steel tube*. The tubular axle is slung from the skids by rubber bands, and carries two wheels oi the disc type. The wings are built up of spruce webs wit h ash flanges over two ash spars of I section. The lift and drift is taken by heavy stranded cables running to the lower members of the chassis, and the warp cables, of which there are three, are secured to a veiy stout steel ring from which another cable runs over pulleys on the chassis to the corresponding ting on the other side.
