D.H.32 360 HP Rolls-Royce "Eagle" Engine
Tho Holder of the Michelin Cup: The Caudron C.60, on which Poiree made his flight, described in FLIGHT last week. This machine, which is one of the Caudron school types, can if desired be fitted with dual control. It is similar to the machine flown by Poiree at Monaco, except that wheels are fitted instead of floats. The engine is a 130 h.p. Clerget, and the main characteristics are as follows: Length over all, 24 ft. 7 ins. Span, upper plane,. 33 ft. 4 ins. Span, lower plane, 31 ft. 4 ins. Wing area, 270 sq. ft. Weight empty, 1,110 lbs Weight fully loaded, 1,900 lbs.
SIDDELEY SINAIA. Designed soon after the first World War, the Siddeley type 103 was a two-motor, long-range, heavy bomber which flew for the first time on 25th June 1921. During 1921, the Siddeley Deasy Motor Car Co., Ltd ., was absorbed by the then new joint holding called Sir W.G.Armstrong, Whitworth Aircraft Ltd, of Coventry - better known today as Armstrong Whitworth Aircraft.
The Sinaia was powered by two 600-h.p. Armstrong Siddeley Tiger engines - the prototype J6858 being painted "bomber green" overall. Provision was also made for the installation of two 480-h.p. Napier Lion engines.
The type 103 Sinaia was designed by Mr. F.M.Green who had joined the Siddeley company after serving on the Royal Aircraft Establishment at Farnborough during the Great War. Unfortunately, records relating to the history and performance of the Sinaia were destroyed by enemy action during World War II. From photographs and drawings three gun positions may be noted - two in rearwards-extended engine nacelles - as well as side-by-side seating for the pilot and navigator/wireless operator.

The Nieuport-Delage "Sesquiplan." 320 HP. Hispano-Suiza Engine
The de Monge biplane.
THE RHON SOARING COMPETITION: The Aachen Glider in Flight. This photograph gives a good idea of the nature of the country over which these gliding and soaring flights are being made.
THE RHON SOARING COMPETITION: Two views of the Aachen glider, which did so well in the turning competition. The attitude and indifference of the cattle indicate that the machine has no engine.
The Rhon Soaring Competition: The Munich glider, which covered a distance of over 2 1/2 miles and remained in the air for over five minutes.
THE RHON SOARING COMPETITION: Two views of the Hannover glider. This machine has footballs instead of wheels with pneumatic tyres - two under the body, one in the nose, and one under each wing-tip.
THE RHON SOARING COMPETITION: Fuselage of the Zeise No. 3.
The Rhon Soaring Competition: Three views of the Zeise No. 3. In the upper view the wings are sloped forward. In the centre view they are straight, and in the lower diagram they are shown swept back.
THE RHON SOARING COMPETITION: The Stuttgart monoplane.
The Rhon Soaring Competition: View of the "Weltensegler" (world-soarer) in flight. A few minutes after this photograph was taken the machine did a righthand turn, got into a nose-dive, and crashed, the pilot (Willy Leusch) dying from his injuries later.
The Rhon Soaring Competition: The series machine of the Segelflugzeug Werke Baden-Baden. Note the unusual arrangement of the wing-tips.
THE RHON SOARING COMPETITION: Freiherr von Luttwitz's monoplane.
The De Havilland "29" commercial monoplane, a 12-seater fitted with a Napier "Lion."
Under the left wing tip may be seen Captain de Havilland and his chief engineer, Mr. Walker.
THE D.H.29 MONOPLANE: Side view.
THE D.H.29 MONOPLANE: Three-quarter rear view. The tail shown in this photograph has been slightly altered, the elevator having horn balances projecting past the end of the tail plane, as shown in the plan view of the general arrangement drawings.
THE NEW DE HAVILLAND MONOPLANE: Two views of the machine in flight. The photographs are published by permission of the Air Ministry, but no technical details may be given.
The D.H.29 Monoplane: Sketch showing Engine mounting, which is a detachable unit.
THE D.H.29 MONOPLANE: The Pilot's Cockpit is placed above the top of the Fuselage and just in front of the Wings.
THE D.H.29 MONOPLANE: The ailerons are given a differential action by having the arms of the rockers of unequal length. A steel tube runs from the rocker to the aileron crank.
THE D.H.29 MONOPLANE: Details of the fitting which secures the wings to the top longerons of the fuselage.
THE D.H.29 MONOPLANE: 1. The steel tube which runs from the transverse shaft to the elevator crank is provided with leather protectors. 2. Steel rods are employed wherever the control cables have to pass through guides. 3. A spring loaded setting of the elevator takes the place of the usual trimming tall plane.
SOME WING DETAILS OF THE D.H.29 MONOPLANE: 1. Location of the Starboard Petrol Tank. 2. Details of Rib Construction. 3. Sketch showing spar construction. 4. The two halves of the wing are joined as shown, by L-section forgings, steel plates, through-bolts and tubular rivets. 5. Compression strut attachment 6. The tubular wing tip and its attachment to spars. 7. Construction of leading edge and nose ribs.
SOME DETAILS OF THE UNDERCARRIAGE OF THE D.H.29 MONOPLANE: 1. General arrangement of the undercarriage. 2. Details of the swivel attachment of the front chassis strut to lower longeron. 3. Ball-and-socket attachment of rear chassis strut. 4. Details of the rubber shock-absorbers and oleo gear. Note how the arrangement has been simplified as compared with that of the D.H.18.
