red750 Posted February 14 Author Share Posted February 14 The de Havilland C.24 was a two-seat autogyro built by de Havilland at its Stag Lane works in England in 1931. The C.24 was built in 1931 using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120 hp Gipsy III engine. It was withdrawn from use by December 1934. A single example (G-ABLM) was produced and is part of the Science Museum collection. In 1932, it was redesignated C.26 (not to be confused with the unbuilt C.26 twin-engine autogiro design) when a two-blade rotor system was installed. Since 2008 it has been on loan to the de Havilland Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire. In flight, it had a maximum speed of about 115 mph (185 km/h; 100 kn). 1 1 Link to comment Share on other sites More sharing options...

onetrack Posted February 18 Share Posted February 18 The manufacturer is claiming they will only be leased, not available for purchase, and they will only cost $15 hr to operate? I wonder who was smoking what, when they came up with that figure?? Of course, I guess they were only costing battery energy costs, they conveniently forgot to mention the $500 hr in development, repair, maintenance, computerisation, testing, and hull losses costs. See inside a new pilotless cargo plane, which has a nose-loading door like the Boeing 747 and can fly up to 200 miles WWW.BUSINESSINSIDER.COM So far, the company has secured over 80 orders for Pelican Cargo, and it expects the first commercial flight to take place in the second half of 2023. 1 Link to comment Share on other sites More sharing options...

kgwilson Posted February 18 Share Posted February 18 Yep but if you don't have a pilot there are no wages to pay, or insurance premiums, or worksafe fees etc. 1 1 Link to comment Share on other sites More sharing options...
T510 Posted February 18 Share Posted February 18 You still need a pilot in Australia, they just won't be sitting in the plane. The pilot will also need IREX to do BVLOS flights with that sort of aircraft and getting the approvals to fly it will be challenging. 1 Link to comment Share on other sites More sharing options...

If it stalls at 35 knots - it won't land at 45 knots. Cruise at 70 knots - I would expect a wing giving this sort of performance, to stall a lot lower than 35 knots Climb rate - doesn't look like MTO Link to comment Share on other sites More sharing options...

red750 Posted March 7 Author Share Posted March 7 The Stearman XA-21 (Model X-100) was a competitor in a United States Army Air Corps competition for a twin-engined attack aircraft which (after redesigns) led to the Douglas A-20 Havoc, Martin A-22 Maryland and North American B-25 Mitchell. The X-100, designated XA-21 following purchase by the Army Air Corps, was a twin-engined high-winged monoplane of all-metal construction. Its initial design featured an unusual "stepless cockpit" arrangement, much like those on most German World War II bombers designed during the war years from the He 111P onwards, with a streamlined, well-framed greenhouse canopy enclosing both the pilot and bombardier stations. The XA-21 was first tested with the streamlined cockpit but this configuration was found to restrict the pilot's forward vision, and the aircraft was rebuilt with a conventional (stepped) nose and cockpit structure. Although this change in the cockpit did not significantly affect performance, the XA-21 was not ordered into production.' The sole XA-21 had serial number 40-191. 2 Link to comment Share on other sites More sharing options...
red750 Posted March 8 Author Share Posted March 8 The Blackburn B-20, an experimental aircraft that took to the skies in 1940, was designed to significantly enhance the efficiency of flying boat models. Blackburn Aircraft initiated a self-directed design exploration, grounded in a patent submitted by their lead designer, John Douglas Rennie, which featured a retractable pontoon float that doubled as the planing hull. The B-20 aimed to merge the prime attributes of the flying boat and the floatplane. When on water, it functioned primarily as a floatplane, supported by a substantial float beneath the fuselage for buoyancy, complemented by two smaller floats near the wingtips ensuring stability. Once airborne, the central float retracted upward into the fuselage, snugly fitting into a "notch" to streamline seamlessly with the fuselage, while the wingtip floats, akin to the design on the American Consolidated PBY flying boat, extended outward to form the wingtips. This innovative design provided optimal wing incidence for both takeoff and flight, significantly reducing the drag typically associated with the deep hulls of traditional flying boats. Only 1 built.

red750 Posted March 9 Author Share Posted March 9 The Pander S-4 Postjager was a 1930s Dutch three-engined mailplane designed and built by Pander & Son. Only one was built which was destroyed during the MacRobertson Air Race. The S-4 was designed as a fast mailplane for the service between the Netherlands and the Dutch East Indies. It was a three-seat low-wing monoplane powered by three 420 hp (313 kW) Wright Whirlwind radial engines. It had a conventional retractable landing gear with a tailwheel. The S-4, registered PH-OST, first flew on 6 October 1933. In December 1933 it flew a mail flight to Batavia. In 1934 the S-4 was entered into the MacRobertson Air Race between London and Melbourne. It left Mildenhall in England on 20 October 1934 and after 36 hours arrived at Allahabad, India. The aircraft was delayed when the landing gear was badly damaged on arrival at Allahabad. It was ready to leave on 26 October but while taxiing for departure it hit a motor car and burst into flames and was destroyed; the crew jumped out and escaped injury. 2 Link to comment Share on other sites More sharing options...
red750 Posted March 11 Author Share Posted March 11 The Andiel Typhoon TD1 is a homebuilt, two place low wing recreation aircraft designed and built in Australia by Willy Andiel. It first flew in April 2003 powered by a 100hp VW RG TT 2000 engine and features an all-flying tailplane. The vision was to make plans available to kit builders, however this did not eventuate and it was withdrawn from use in 2011. This one-off aircraft was donated to HARS Parkes and recovered from Cowra. The engineering team has been working to restore it to display condition.

red750 Posted March 11 Author Share Posted March 11 The Couzinet 10 Arc-en-Ciel ('Rainbow') was built as a first example of the three-engined, aerodynamically refined, cantilever low wing monoplane designer René Couzinet thought offered the safest long range passenger transport, for example on the South Atlantic route. Only one was completed, though other, similar aircraft of different sizes and powers followed. The Couzinet 10 was the first of his designs to be built, though it was the result of his design study number 27. It led to the smaller Couzinet 20 and 30 series and the larger Couzinet 40 and 70. The one-piece wing of the Couzinet 10 was 900 mm (35.4 in) thick at the root, a thickness to chord ratio of 18%, and thinned continuously out to the tip. In plan each wing was trapezoidal, though long tips produced an approximately elliptical form. Long, narrow-chord ailerons filled most of the straight part of the trailing edges. It was entirely wooden, built around two box spars and plywood covered. The Arc-en-Ciel was powered by three 170 kW (230 hp) Hispano-Suiza 8Ac water-cooled upright V8 engines. One was in the nose and the other two ahead of the wing leading edge, all within cowlings that followed the V8's cylinder heads and cooled with Lamblin radiators. Seven wing fuel tanks held a total of 6,200 L (1,400 imp gal; 1,600 US gal).[3] The thickness of the wing at its root allowed crew to reach the engines in flight via a corridor 700 mm (27.6 in) high. 2 Link to comment Share on other sites More sharing options...
red750 Posted March 12 Author Share Posted March 12 The Fokker F.XX was a 1930s Dutch three-engined airliner designed and built by Fokker. It was the first Fokker design to use an elliptical-section fuselage instead of the traditional square fuselage and the first Fokker aircraft with retractable landing gear. The F.XX was a high-wing thick-section cantilever monoplane with a retractable tailwheel landing gear. It was powered by three Wright Cyclone radial engines, one in the nose and one under each wing on struts. The main landing gear retracted into the engine nacelles. The F.XX registered PH-AIZ and named Zilvermeeuw (en: Silver Gull) first flew in 1933. It was delivered to KLM for services from Amsterdam to London and Berlin. Although the F.XX was a more advanced design both in aerodynamics and looks than earlier Fokkers, the arrival of the twin-engined low-wing Douglas DC-2 and DC-3 soon rendered it obsolete. Only one aircraft was built, and after service with KLM was sold to French airline Air Tropique; the plane got a camouflage paint scheme and was registered F-APEZ. Air Tropique had ties with the Spanish Republican government, that used the plane to operate a liaison service between Madrid and Paris. In 1937 it went to LAPE in Spain, and was registered EC-45-E. The plane crashed in Spain February 15, 1938 near Barcelona at Prat de Llobregat Airport. Licence production in the UK as the Airspeed AS.21 was not proceeded with. 1 Link to comment Share on other sites More sharing options...
