The principal elemem of the training apparatus is a single-rotoi,single-seater helicopter which can both iurn and change its altitude when mounted on arevolving ground support. All manoeuvres of a flying helicopter can be practised withthe float-mounted trainer. Elastic slops prevent any damage, even when the controlsare fully and quickly actuated. On the water an air-filled stabilizer ring limits theinclinations by the longitudinal and trans- verse axes. Aero Lualdi & C Via Panama 95, Rome L.59 The L.59 is the latest of a series ofLualdi light helicopters and has a rotor of the type fitted to the Hiller UH-12E, witha Lualdi gyro-stabilizer. Construction is all metal and the engine is a ContinentalIO-470-D of 260 h.p. The four seats are arranged in two pairs, with dual controls forthe front pair. There are car-type doors on each side and provision is made for carryingtwo stretchers. (Data on next page.) VWL I NTER NATION AL SURVEY... FRANCE Sud Aviation 37 Bd de Montmorency, Paris I6eAlouette II One of the most successful helicopters yet produced, the Alouette 11is powered with a Turbomeca Artouste 2 shaft turbine of 400 s.h.p. It is charac-terized by a glazed cabin and an unfaired steel tube rear fuselage. Typically a five-seater, it accommodates pilot and a pas- senger side-by-side, and three passengers atthe rear. Two stretcher cases can be taken in the ambulance role in addition to twositting patients and a medical attendant. A notable feature introduced on this air-craft is the automatic engine r.p.m. govern- ing system designed to simplify piloting. • Rotor diam, 33ft 6in; fuselage length,31ft lOin; gross weight, 3.3001b; cruising speed, 106 m.p.h.: hovering ceiling (free air),6,500ft; range, 290 n.m. Alouette III A derivative of the Alou-ette II, this version differs from the earlier machine in having a slightly reinforcedtransmission system and in being powered with an Artoustc 3B, a development of theArtouste 2, with more reserve power. Equipment and general layout are im-proved and the whole airframe has been cleaned up; particularly noticeable is thesemi-monocoque tail boom. Two baggage holds are provided in the centre portion, on either side of the welded structure andenclosed by fairings. The cabin seats three at the front and there is a four-place foldingseat at the rear. Two stretchers can be accommodated athwartships in the rearcabin.

Djinn Powered with a TurbomecaPalouste turbine air-generator, the two- seat Djinn continues in production. • Rotor diam, 36ft; fuselage length, 17ft5in; gross weight, 1,6761b; cruising speed, 62 m.p.h.; hovering ceiling in ground effect,3,000ft; service ceiling, 10,000ft; max range, 110 miles. Frelon A production version of thislarge helicopter is reported to have a six- blade rotor and flying-boat hull. Like theprototypes it will be powered by three Turbomeca Turmos. A full-scale mock-upis expected to be at the Paris Salon.
