FLIGHT, 6 September 1957 415 f HA-001 A New Agricultural Type Under Test in Holland Powered by the Lycom'mg 135 h.p. engine, the HA-001 has a wing-span of nearly 50/t.J undergoing flight-testing in Holland is the HA-001, de--1- ~ signed by Hollandair of Katwijk and powered by a Lycoming 135 h.p. engine. As recorded in our issue of August 16, it madea successful first flight a few weeks ago at Zestienhoven, near Rotterdam. The wooden, fabric-covered wing, which spans 15 m (49ft 2in),has no flaps. Steel tubing forms the fuselage structure, the pilot being lodged in a cockpit with no side screens to facilitate escapein case of accident. Immediately behind him is space for a dust hopper, but this is not yet fitted. Alternatively a passenger couldbe accommodated. First equipment will be for spraying, for which The new Lear omni-navigation dial. LEAR OMNI-NAV INSTRUMENTS "TWO new omni-navi-•*- gation units are announced by Lear,Inc., of Santa Monica, California. The Model4080 OmniMeter is an indicator designed to fitany V.O.R. receiver conforming to ARINCstandards. The same indicator can bematched with the Model 2372 Vortranwhich is a convenor designed to adapt plainV.H.F. receivers for V.O.R. operation. It isclaimed that Vortran is fully transistorized. The new dial, illus-trated here, has a rotat- ing dial, marked indegrees, on which the desired V.O.R. radial to be flown is set against the top lubber mark. Reciprocal headings are shown, rightway up, on the lower edge of the dial. The vertical needle then gives error signals to direct the pilot onto the required radial."To" or "from" indications appear in the form of an arrow in one of the two small windows in the dial face. Blue and yellowsegments under the moving tip of the needle are for use when an I.L.S. localizer beam is being flown. POLISH INDUSTRY PROGRESS RECENT reports from Warsaw have stated that the total valueof Polish civil aircraft produced during 1957 will amount to a 25 per cent increase over last year's figure. Highest productionfigures are those for the licence-built Yak-12, said to have been supplied for both Polish and export markets. Production of theBies and of the SM-1 helicopter (to be exported to Russia, East Germany, Bulgaria and Austria) is well under way.Of the total 1957 value of Polish-built aircraft, 400m zloty (approximately £6m), gliders for export account for 30m zloty(£450,000). The Bielsko gliding centre is now building a proto- type all-metal, tailless glider; other current Polish projects includethree all-metal aircraft which are being built by students of Warsaw Polytechnic; the M-2 low-wing two-seater in the D.H. Chipmunkclass; the M-3 single-seater sailplane; and the M-4 aerobatic single- seat aeroplane equipped with a retractable nosewheel under-carriage. The MD-12 light transport has been developed into a four-engined machine powered by WN-3 320 h.p. radials. For the future, the fully developed version will have two Narkiewiczturboprops each of 1,000 h.p. and will cruise at 168 m.p.h. with 20 passengers or 3,750 lb payload. The prototype of the S-4Kania 2 is about to make its first flight, powered by the new 180 h.p. WN-6 engine. First pre-production models of the T5-8 Bies are now in final a bar, Shell disc dispersers and a pump are to be fitted. Later anair pressure system will replace the pump. Spray liquid will be carried in two 40-gal underwing tanks.The HA-001 was designed by Hollandair for Luchtyaartbedrijf Nederland of Groningen, who already operate one Piper Super-Cub for spraying. Subsequent HA-OOls may have Lycoming 150 h.p. or even 200 h.p. engines. With the 135 h.p. engine,take-off and landing runs are 110 yd, full-load stalling speed 40 m.p.h., best spraying, climbing and turning speed 56 m.p.h.,initial rate of climb 1,200ft and cruising speed between 80 and 90 m.p.h. according to the propeller fitted. stages of assembly at W.S.K. in Warsaw, while the main produc-tion line is being established at Mielec. A prototype Bies set up an international speed record for its class over a 2,000 km closedcircuit at 197.5 m.p.h. recently. A new pulsejet helicopter designed by J. Kotlinski, the Trzmiel,has been completed and is now undergoing trials. Another heli- copter, a twin pulsejet ultra-light designed by Matula, is nearingcompletion. Initial design study of a manned earth satellite project, nuclear-powered, will begin in September and is expected to take some three years. AERO COMMANDER RECORDS RECENTLY established by Miss Jerrie Cobb in Aero Com-mander aircraft were world class records (subject to con- firmation) for altitude and distance. The former was achieved ina Commander 680 Super which climbed to 30,330ft over Oklahoma City, a few weeks after Miss Cobb had flown 1,522 miles fromGuatemala City to Oklahoma City in a Commander 560-E. Both Miss Cobb in the 680 Super. machines were standard production models. The Aero Com-mander 560-E has a span of 49ft and a gross weight of 6,500 lb. Powered by two 295 h.p. Lycoming engines, it cruises at 210m.p.h. at 70 per cent power at 10,000ft. JAPAN'S AIR DEFENCE WHAT Tokyo radio described as a "sweeping reorganizationof Japan's Air Self-defence Force" has been decided upon by the Defence Board. The main purpose of this reorganization—due to be carried out during the financial year starting next April —is to enable the Japanese Air Force to take over air defenceduties from the U.S.A.F. units which are "now withdrawing from Japan." During the 1958-59 financial year the first independentJapanese radar group is to be set up; it will take over ten radar stations from the U.S. Far East Air Force.
