NOVEMBER 28, 1918 THE JUNKER ARMOURED BIPLANE.—Top : Front portion of fuselage, with engine,of top-plane centre-section. Bottom : End view the maximum thickness of the top plane being about 16 in.The chord of tftis wing is a little over 8 ft. while the chord of the bottom plane is approximately 5 ft.From the fact that no trace was found of inter-plane strut fittings it would appear that these members have been dis-pensed with in the Junker. It appears that the top plane centre-section was carried on a structure of tubes from thebody, while the bottom plane appears to have been attached to the bottom of the fuselage by a series of diagonal struts.This arrangement, which would be made possible by employ- ing such a deep wing section, would have the advantage thatthe gunner could fire forward at a considerable angle without danger of hitting a vital member of the wings. The undercarriage is in the form of two Vees, attached tothe lower plane some distance out. From this point the bracing tubes of the bottom plane run to the body, thustransmitting the shock to the fuselage without, presumably, causing excessive bending stresses in the lower wing spars.The wing covering is in the form of corrugated aluminium sheet, and it was noticed that this did not form a fair curveover the wing framework, but was rather in the nature of a series of straight lines. This could hardly improve theaerodynamic qualities of the wing section, but on the other hand it is possible that the effects are not great. Later wehope to be able to give some details of this interesting machine. The Enemy Aircraft ExhibitionIT has now been decided to throw the Enemy Aircraft Exhibition at the Agricultural Hall open to the public onall weekdays and to extend the hours during which it is open from 10 a.m. to 10 p.m. It will also be open from'3 p.m.to 10 p.m. on Sundays. An Aero Exhibition Next YearAN announcement has been issued by the Society of Motor Manufacturers and Traders setting forth their intention to organise forthwith a full series of Exhibitions. Theannual Touring Car Exhibition will be held at Olympia in November, 1919, and the series of International AeroExhibitions commenced in 1909 is to be forthwith resumed, and it is confidently anticipated that there will now not bethat lack of public interest in aircraft which caused past exhibitions to prove a serious financial losst Exhibitionsof commercial and agricultural motors and marine equip- ment are also promised. 1357
