The PARIS AERO SHOW

LIORE AND OLIVIER

   This stand is dominated by the huge metal hull of a flying boat, the LeO H.27. Wing roots in placed in the hull indicate that the machine will be a cantilever monoplane, but there is no indication as to where the engines will go. One assumes that, as the machine is stated to be a four-engined type, the power plants, which will be 4 Hispano-Suizas of 650 h.p., the engines will be placed in tandem pairs on top of the wing. The hull is metal plated, and the machine is believed to be intended, when finished, for the transatlantic service. It can be equipped either as a mail-carrier or as a passenger machine.

The Liore et Olivier 24-2

   INTENDED for the Marseilles-Algiers route of Air-France, the LeO 24-2 is a cantilever monoplane flying boat, with four Gnome-Rhone K.7 engines mounted in tandem pairs above the wing. The aircraft has been developed from the LeO 24 commercial flying boat, the good aerodynamic characteristics of which are preserved.
   The wooden monoplane wing, which is in three sections, tapers both in chord and thickness, and is divided into a number of watertight compartments which would support the machine in the event of a forced landing. Plywood covering is used for the wing. All members of the empennage are of duralumin covered with fabric.
   All metal construction is used for the hull. It is a single step flat-sided structure, close attention having been given to the question of accessibility to the interior. A mooring position is in the bows, and immediately behind this is the pilots' cabin with dual controls. The position for the navigator and the wireless compartment is behind and below the cockpit. To the rear of this, below the wing, is the passenger cabin which may be arranged to accommodate from ten to fifteen passengers. Behind the cabin is a lavatory and a baggage compartment.
   Four Gnome-Rhone K.7d radial engines of 370 h.p. each are mounted in two nacelles above the wing, where the metal airscrews are well clear of the spray. In place of the four K.7's, two Gnome-Rhone 14K. engines may be used, when the boat is known as the type 24-3, and a top speed of nearly 175 m.p.h. is obtained. The machine flies easily with one engine stopped.

THE FOURTEENTH PARIS AERO SHOW

THE EXHIBITS DESCRIBED

Marine Aircraft

<...>
   France's contribution to commercial marine aviation takes the form of the Liore et Olivier LeO H.24. This is a four-engined flying boat designed for the Marseilles-Algiers route, and is a high-wing monoplane of "mixed" construction, with a metal hull and an all-wood cantilever wing.
   The four Gnome-Rhone engines, of the 7 Kd type and 350 h.p. each, are placed on trestles above the wings, in two tandem pairs. Lateral stability on the water is obtained by two outboard floats, each placed approximately half-way along the semi-span. The machine has a gross weight of 8400 kg. (18,400 lb.), and is equipped to carry eleven passengers. The total pay-load, when the range is 600 miles, is 4,800 lb.
