The D.H.50 biplane, 230 h.p. Siddeley "Puma": It •was on a similar machine to this, G-EBFP, that Alan Cobham made his splendid flight to Tangier and back.
MOROCCO BOUND: Our photograph shows the Spanish aircraft carrier "Dedalo," with a number of Supermarine flying boats stowed on deck, steaming down Southampton Water en route for Morocco. No doubt upon arrival the Spanish forces will greet them with "the 'moor' the merrier."
The Parnall "Pixie" two-seater light 'plane has a forced landing. On a recent flight the machine came down at Henbury owing to plug trouble. It had its wings folded, was pushed through four gateways to a larger field, from which it took off quite easily, and returned safely to the Filton Aerodrome.
The Parnall "Pixie III," with wings folded for transport. Note the neat cowling around the Bristol "Cherub" engine. The cantilever undercarriage should be observed.
Side elevation of the Parnall two-seater light monoplane.
SOME CONSTRUCTIONAL DETAILS OF THE PARNALL TWO-SEATER LIGHT MONOPLANE: 1. A wing root, showing trunnion for attachment to fuselage. 2. The wing in place, showing attachment. 3. Lay shaft and cranks of the elevator. The tail plane tube has been omitted for the sake of clearness, as has also the tail skid, which is made from cane. 4. Details of the differential aileron control. The two cables run to the controls in the cockpit. 5. Shows the spar construction. 6. The lift tubes are attached not direct to the spar, but to the tubular compression strut of the drag bracing, so that the angularity of the lift strut does not produce twist in the spar.

THE BRISTOL "BROWNIE," BRISTOL "CHERUB" ENGINE: Front view.
THE BRISTOL "BROWNIE" LIGHT MONOPLANE, BRISTOL "CHERUB" ENGINE: Three-quarter front view.
SOME BRISTOL "BROWNIE" CONSTRUCTIONAL DETAILS: Some of our sketches show features common to all three Bristol machines, but those relating to the wing structure show the all-metal construction. 1, the root of the port wing. Note the very original spar web, consisting of a circular steel tube bent zig-zag fashion and flattened out at the points of attachment to the spar flanges. 2, details of the attachment of the leading edge. 3, 4 and 5, details of the spar construction. Towards the wing tip, where the spar depth becomes smaller, the zig-zag web is not continued, and the construction is of the form shown. 6 illustrates the mounting of the "Cherub" engine on four tubular cantilever pillars without bracing. These pillars are permanently bolted to the engine, and are attached to the engine bulkhead by unions. 7 shows the attachment of the wing to the fuselage. A wood bulkhead is built-in at this point, although the fuselage is of steel tube construction, and the upper spar flange attachment has provision for setting dihedral and incidence by the micrometer adjustment shown. 8 shows a typical fuselage joint.

THE "A.N.E.C. II" MONOPLANE: Three-quarter rear view.
The Anzani engine in the "A.N.E.C. II" monoplane. Note the inverted position.
THE "A.N.E.C. II" LIGHT MONOPLANE: This three-quarter front view gives a good idea of the lines of the machine, which are exceptionally "clean." Note the inverted position of the 1,100-c.c. Anzani engine, and the manner in which this mounting improves the view. Gravity feed from the tank in the deck fairing is also facilitated.
ONE OF TWO PRIZE-WINNERS AT LYMPNE: James's A.N.E.C. monoplane (No. 17), on which he tied with Flight-Lieut. Longton, flying the "Wren" No. 4, for the Duke of Sutherland's and the "Daily Mail" prizes.
SOME CONSTRUCTIONAL DETAILS OF THE A.N.E.C. MONOPLANE: 1, A general view of one side of the very simple undercarriage. The axle is a bent tube, so fixed in the sides of the fuselage that it cannot turn. The only springing is that provided by the flexibility of the axle, and by the pneumatic tyres. The view in Fig. 2 gives an idea of the general arrangement of the chassis. 3 shows the root of the port wing with cut-out portion for front cockpit. The wing spars are hinged to the top fairing of the fuselage. 4, Details of the lift-strut attachment to the wing spar. The lower end of the strut is secured to the fitting shown in 1. The tail, Fig. 5, is attached to the stern of the fuselage as shown, the fin being in two sections of which one is integral with the fuselage structure. The elevator carries out the lines of the fuselage, and is hinged at its upper edge, being operated by a push-and-pull rod from the body.

REMINISCENCES OF LAST YEAR'S LYMPNE COMPETITIONS: The picture shows Hinkler flying the Avro monoplane on which he covered a distance of 1,000 miles during the week, while inset is the A.N.E.C. monoplane on which James tied with Longton.
FROM THE RHON MEETING: The Darmstadt "Konsul" making a landing on a predetermined spot. It was on this machine that Botsch flew 19 kilometres last year. Note the extremely high aspect ratio.
The "Roemryke Berge" of the Lower Rhenish Aero Society starting for a flight. This photograph shows admirably the nature of the country in the Rhon.
AN ARCTIC AVRO: These photographs show the Avro-"Lynx" of the Oxford University Arctic Expedition, which, under Mr. George Binney, has been making good use of the seaplane. The machine and its Armstrong-Siddeley "Lynx" carries a very heavy load, but nevertheless on test got off the water easily. The general views, 1 and 5, give a good idea of the lines of the machine. In 2 it is seen taxying, while 3 shows the special engine mounting designed for the "Lynx." A cowl is, of course, fitted for actual flying in the Arctic. 4 shows the Norwegian sled carried under the deck fairing. The front view, 6, shows the long floats, and the two extra petrol service tanks under the top plane. A third tank is built into the top centre-section.
THE SHORT "SATELLITE," BRISTOL "CHERUB" ENGINE: Three-quarter front view from above.
THE SHORT "SATELLITE": Three-quarter rear view, from above.
The Short "Satellite" starting on a flight.
SOME SHORT CONSTRUCTIONAL DETAILS: 1. The very neat engine mounting for the Bristol "Cherub." This mounting should be particularly good in respect of torsional stresses. 2. The oleo undercarriage. 3. Attachment of tail skid fixed end to fuselage. 4. The renewable shoe on the free end of the tail skid. 5. An aileron hinge. 6. The port wing root showing inspection doors giving access to wing attachments. The ailerons are operated by torque tubes.
A SCHOOL MACHINE AT RHON: A pupil starting on his first flight in a Martens School biplane, the simple and robust construction.
Light Planes at Rhon: The Baumer Aero "Roter Vogel" (No. 74) is fitted with a Douglas engine mounted in a somewhat unusual position. The machine is of usual glider type, and the placing of the engine, with long shaft to tractor airscrew, has evidently been chosen to obtain correct trim.
The Udet "Kolibri" and the Baumer "Roter Vogel" in the air together in the Rhon.
In the Rhon: Prince Heinrich inspects the Messerschmitt light 'plane which is fitted with a Douglas engine.
The Martens family: This photograph shows Herr and Frau Arthur Martens standing by the Martens "Windhund" light 'plane. The machine has a Douglas engine.
No.55, the Blume-Hentzen "Habicht," starting on a flight in the Rhon. This machine is fitted with a 750 c.c. Siemens engine.
A Weltensegler light biplane: The pilot is Herr Wolff Hirth, brother of the famous German pilot Hellmuth Hirth.
THE SUPERMARINE "SPARROW": Three-cylinder Blackburne engine. Three-quarter front view.
Not a Helicopter, but the Supermarine "Sparrow" light biplane, with wings partly folded. Note the three-cylinder Blackburne engine. The man on the left, who appears to be threatenting Mr. Mitchell with a club, is not, we hope, really in earnest.
SOME SUPERMARINE "SPARROW" CONSTRUCTIONAL DETAILS: 1 shows one of the telescopic legs of the undercarriage. The crutches are covered with leather. 2, the complete undercarriage. 3, the very simple device for setting the wing flaps. Rotating the small wheel shortens or lengthens the positive cables the balance or return cables having rubber cords so as to adapt themselves to the varying length. In 4 is shown an aileron hinge, while 5 shows the construction of the lower plane.
Supermarine "Sparrow" 2-seater Light Biplane
No. 5, THE WESTLAND "WOOD PIGEON": Three-quarter rear view.
Scale model of the Westland "Wood Pigeon" light biplane.
SOME WESTLAND CONSTRUCTIONAL DETAILS: 1. Shows the rack and pinion by which the locking pin in the lower end of the front inter-plane strut is brought into engagement with the lug on the fuselage. The pin is withdrawn from the fuselage lug by a turn of the pinion, using a special spanner, and the wing can then be folded. A further turn brings the pin right out of the spar fitting, and the strut can then be removed from the wing. 2 shows the fuselage fitting, and 3 the strut in position with wing spread. 4. Gives details of the tubular engine mounting and its attachment to fuselage. 5. Details are given of the wing construction of the Westland monoplane two-seater. The spars consist of a central three-ply web, with divided flanges and lattice bracing, all of wood.

THE AVRO "AVIS": View of the engine mounting, undercarriage, etc.
THE AVRO "AVIS," BLACKBURNE RADIAL ENGINE: Side view.
THE AVRO "AVIS." SOME CONSTRUCTIONAL DETAILS: 1, the very beautifully-made wing flap gear. Rotation of the worm gear raises the longitudinal shaft, and with it the crank joined to the two wing flap cranks. The result is that both ailerons are depressed. Shafts, etc., work in ball bearings. 2 shows how a parallel movement is imparted to the stirrups of the front foot bar. In 3 is shown, cut through to show the construction, the foot of the inter-plane I-strut. Note the unusual bracing, with struts running diagonally to the spars and a tie-rod from front to rear spar. 4 shows the rib construction and attachment to tubular leading edge, and 5 an aileron and its attachment to the Duralumin torque tube.
