Experimental aircraft walkaround vol.10: Dassault Mirage IIIV


Subject: Dassault Mirage III V
Location:Musée d'lair et de l'espace, Le Bourget, Paris, 2015
Comments: The Dassault Mirage IIIV, also spelled Mirage III V, was a French vertical take-off and landing (VTOL) prototype fighter aircraft of the mid-1960s developed and produced by Dassault Aviation.The Mirage IIIV was a VTOL derivative of an existing conventional fighter, the Dassault Mirage III; the principal difference between the two types was the addition of eight small vertical lift jets which straddling the main engine. These lift jets would have been used during vertical takeoffs and landings, but would have been inactive during horizontal flight. The Mirage IIIV had come about as a response to the issuing of a NATO specification, NATO Basic Military Requirement 3 (NBMR-3), which sought a supersonic-capable VTOL strike fighter. The Mirage IIIV was a competitor with Hawker Siddeley's P.1154 VTOL fighter, a cousin of the Hawker Siddeley Harrier. Both aircraft competed to be selected to meet the NBMR-3 requirement. While the Mirage IIIV is commonly viewed as being more politically palatable due to an emphasis having been placed upon multinational development and manufacturing plans, the design of P.1154 (which only used a single engine) was seen as more straightforward and practical. Ultimately the P.1154 was selected to meet the NBMR-3 requirement to the detriment of the Mirage IIIV. One of the two prototypes constructed was destroyed in an accident; shortly following its loss, the whole project was abandoned; the surviving aircraft has since been placed on public display.

Experimental aircraft walkaround vol.9: Morane Saulnier Type G



Subject: Morane Saulnier Type G
Location:Musée d'lair et de l'espace, Le Bourget, Paris, 2015.
Comments:The Morane-Saulnier G was a two-seat sport and racing monoplane produced in France before the First World War. It was a development of the racing monoplanes designed by Léon Morane and Raymond Saulnier after leaving Borel and, like its predecessors, was a wire-braced, shoulder-wing monoplane. Construction was of fabric-covered wood throughout, except for the undercarriage struts which were of steel tube. The type was a sporting success. In April 1913, Roland Garros took second place in the inaugural Schneider Cup in a floatplane version, finishing with a time of 40 minutes 40 seconds. On 26 June, Claude Grahame-White flew another float-equipped example from Paris to London via Le Havre, Boulogne-sur-Mer, and Dover, covering some 500 km (310 mi) that day. Between 21 and 28 September the same year, two float-equipped Type Gs competed at the seaplane meeting at San Sebastián, with Lord Carbery winning the short takeoff prize on one, and Edmond Audemars winning the maneuverability prize on the other. The following week, Carbery flew his Type G in the Italian Waterplane Contest from Lake Como to Pavia and back, along with two other Type Gs in the field of fifteen competitors, these flown by Garros and Morane. Garros not only won the Grand Prize in the "general class", but also the prizes for best speed (127.7 km/h, 79.8 mph) and greatest altitude (2,100 m, 6,000 ft).On 28 September 1913 Roland Garros became the first person to cross the Mediterranean Sea by air, flying from Fréjus in the south of France to Bizerte in Tunisia in a Morane-Saulnier G.In 1914, Russian manufacturer Duks arranged to build the type under licence at their Moscow factory for the Russian Army, and the same year, the Turkish military ordered 40 examples. Before these could be delivered, however, war broke out, and the aircraft were impressed into the French Army. To these, the Army soon added an order of 94 aircraft, and the British Royal Flying Corps also acquired a number, these latter machines purchased from Grahame-White, who was manufacturing the type in the UK under licence. At the outbreak of war, the type's military value was found to be wanting, and the French machines were quickly relegated to training duties

Experimental aircraft walkaround vol.8: Dewoitine D530




Subject: Dewoitine D530
Location:Musée d'lair et de l'espace, Le Bourget, Paris, 2015.
Comments: The Dewoitine D530 was a derivative of an earlier design by Émile Dewoitine back in 1928 called the D.27. The Dewoitine D.27 was a parasol monoplane fighter of witch 66 were operated by the Swiss Air Force beginning in 1931. The D530 incorporated a new Hipsano-Suiza engine and reinforced wings by request of the famous french Pilot Marcel Doret. The plane's first flight occurred in 21 april 1937 and Doret last flight on this aircraft was made in 1955 between Aimes and Reims in france, shortly before Doret's death.

Experimental aircraft walkaround vol.7: Dassault Rafale A


Subject: Dassault Rafale A
Location:Musée d'lair et de l'espace, Le Bourget, Paris, 2015.
Comments:The Dassault Rafale (French pronunciation: ​[ʁafal], literally meaning "gust of wind", and "burst of fire" in a more military sense) is a French twin-engine, canard delta wing, multirole fighter aircraft designed and built by Dassault Aviation. Equipped with a wide range of weapons, the Rafale is intended to perform air supremacy, interdiction, aerial reconnaissance, ground support, in-depth strike, anti-ship strike and nuclear deterrence missions. The Rafale is referred to as an "omnirole" aircraft by Dassault.In the late 1970s, the French Air Force and Navy were seeking to replace and consolidate their current fleets of aircraft. In order to reduce development costs and boost prospective sales, France entered into an arrangement with UK, Germany, Italy and Spain to produce an agile multi-purpose fighter, the Eurofighter Typhoon. Subsequent disagreements over workshare and differing requirements led to France's pursuit of its own development program. Dassault built a technology demonstrator which first flew in July 1986 as part of an eight-year flight-test programme, paving the way for the go-ahead of the project. The Rafale is distinct from other European fighters of its era in that it is almost entirely built by one country, involving most of France's major defence contractors, such as Dassault, Thales and Safran.Many of the aircraft's avionics and features, such as direct voice input, the RBE2 AA active electronically scanned array (AESA) radar and the optronique secteur frontal infra-red search and track (IRST) sensor, were domestically developed and produced for the Rafale programme. Originally scheduled to enter service in 1996, the Rafale suffered significant delays due to post-Cold War budget cuts and changes in priorities. The aircraft is available in three main variants: Rafale C single-seat land-based version, Rafale B twin-seat land-based version, and Rafale M single-seat carrier-based version. Introduced in 2001, the Rafale is being produced for both the French Air Force and for carrier-based operations in the French Navy. The Rafale has been marketed for export to several countries, and was selected for purchase by the Indian Air Force, the Egyptian Air Force, and the Qatar Air Force. The Rafale has been used in combat over Afghanistan, Libya, Mali, Iraq and Syria. Several upgrades to the weapons and avionics of the Rafale are planned to be introduced by 2018. The Rafale A technology demonstrator was a large-delta winged fighter, with all-moving canards, embodying fly-by-wire (FBW) flight control system. Construction of the demonstrator commenced in March 1984, even before a contract was signed with the DGA, France's defence procurement agency. The technology demonstrator was rolled out in December 1985 in Saint-Cloud, and took its maiden flight on 4 July 1986 from Istres-Le Tubé Air Base in southern France. During the one-hour flight, the project's chief test pilot Guy Mitaux-Maurouard took the aircraft to an altitude of 11,000 metres (36,000 ft) and a speed of Mach 1.3. The 9.5-tonne (21,000 lb) demonstrator stopped in 300 metres (980 ft) upon landing

Experimental aircraft walkaround vol.5: Granville Brothers Gee Bee Model R

Subject: Gee Bee Model R
Location: Fantasy of flight Museum, Orlando, Florida, USA 2013
Comments: The 1932 R-1 and its sister plane, the R-2, were the successors of the previous year's Thompson Trophy-winning Model Z. Assistant Chief Engineer Howell "Pete" Miller and Zantford "Granny" Granville spent three days of wind tunnel testing at NYU with aeronautical engineering professor Alexander Klemin. The aircraft had a very peculiar design. Granville reasoned that a teardrop-shaped fuselage — especially as seen from directly above — would have lower drag than a straight-tapered one, so the fuselage was wider than the engine at its widest point (at the wing attachment point). The cockpit was located very far aft, just in front of the vertical stabilizer, in order to give the racing pilot better vision while making crowded pylon turns. In addition, it turned out that the fuselage acted as an airfoil, like the 'lifting-body' designs of the 1960s. This allowed the aircraft to make tight "knife-edge" turns without losing altitude. It was, in effect, a Pratt & Whitney R-1340 engine with wings and a tail on it.The R-1 won the 1932 Thompson Trophy race, piloted by Jimmy Doolittle. He also set a new world landplane speed record of 476 km/h (296 mph) in the Shell Speed Dash. The distinction of a landplane record was noteworthy because, at that time, specialized speed seaplanes outran landplanes (see Schneider Trophy). The Springfield Union of September 6, 1932 quoted Doolittle as saying, "She is the sweetest ship I've ever flown. She is perfect in every respect and the motor is just as good as it was a week ago. It never missed a beat and has lots of stuff in it yet. I think this proves that the Granville brothers up in Springfield build the very best speed ships in America today."The R-1 rapidly earned a reputation as a potentially very dangerous machine. The small wings, very low polar moment of inertia, and tiny control surfaces made for an aircraft that could rapidly get away from all but the most skilled pilots. This shortcoming was common to most air racers of the day. During the 1933 Bendix Trophy race, racing pilot Russell Boardman was killed, flying Number 11. After taking off from a refueling stop in Indianapolis, Indiana, the R-1 stalled, and crashed.The R-1 was later repaired and now incorporated a fuselage extension of approximately 18 inches, creating the "Long Tail Racer." It was decided not to rebuild the wings but to use the original wings from the R-2, which had been removed in February 1933 when a new wing with flaps was built and installed. This aircraft crashed in a landing overrun incident soon after it was built but Roy Minor, the pilot, was not severely injured. After another rebuild, the Long Tail Racer was sold to Cecil Allen. Allen, against the advice of the Granvilles, modified it by installing larger gas tanks aft of its normal center of gravity, which apparently made the aircraft unstable in pitch from tail-heaviness. Allen took off with a full fuel tank, crashed, and was killed. After this final crash, the aircraft was never rebuilt. A flying replica of the R-2 was built by Steve Wolf and Delmar Benjamin that first flew in 1991. Benjamin flew an aerobatic routine in this aircraft at numerous airshows until he retired the aircraft in 2002. This aircraft was sold to and is on display at the Fantasy of Flight museum.

Experimental aircraft walkaround vol.4: Granville Brothers Gee Bee Model Z

Subject: Gee Bee Model Z
Location: Fantasy of flight Museum, Orlando, Florida, USA 2013
Comments:The Granville Gee Bee Model Z was an American racing aircraft of the 1930s, the first of the Super Sportster aircraft built by Granville Brothers Aircraft of Springfield, Massachusetts, with the sole intent of winning the Thompson Trophy, which it did in 1931. However, it soon suffered a fatal crash during a world speed record attempt, starting the reputation of the Gee Bee aircraft as killers. Suffering from the effects of the Great Depression, the Granville Brothers decided in July 1931 to build an aircraft to compete in that fall's Thompson Trophy competition at the National Air Races in Cleveland, Ohio. They hoped that a victory in the prestigious race would lead to additional orders for their line of sporting aircraft. Constructed in less than five weeks at a cost of under $5,000 USD, the Gee Bee (for "Granville Brothers") Model Z, named City of Springfield, was a small, tubby airplane. It was essentially the smallest possible airframe constructed around the largest possible engine, a supercharged Pratt & Whitney R-985 "Wasp Junior" radial engine, producing 535 horsepower (399 kW). First flying on August 22, 1931, the Gee Bee Z quickly proved to be tricky to fly, but fulfilled every expectation with regards to its speed. Flown by pilot Lowell Bayles, the Gee Bee Z attained the speed of 267.342 miles per hour (430.245 km/h) at the National Air Races during the Shell Speed Dash qualifying on September 1, then went on to win the Goodyear Trophy race, run over a course of 50 miles (80 km), the next day at an average speed of 205 miles per hour (330 km/h). On the September 5, the aircraft's engineer, Bob Hall, flew the Gee Bee Z to victory in the General Tire and Rubber Trophy race, then won again the next day in a free-for-all event. In the Thompson Trophy Race on September 7, Bayles was triumphant, winning with an average speed of 236.24 miles per hour (380.19 km/h), winning over competitors including Jimmy Doolittle, James "Jimmy" Wedell, Ben Howard, Dale Jackson, Bill Ong, Ira Eaker, and Hall, who finished fourth in a Gee Bee Model Y. Following the Thompson Trophy race, the Gee Bee Z was re-engined with a larger, 750-horsepower (560 kW) Wasp Senior radial, in preparation for an attempt at establishing a world speed record for landplanes atWayne County Airport in Detroit, Michigan. Unofficially clocked at 314 miles per hour (505 km/h) on a trial run, it surpassed the previous record of 278 miles per hour (447 km/h) by attaining 281.75 miles per hour (453.43 km/h) on December 1, 1931, but the margin was too small for the record to be officially registered. A further record attempt on December 5, 1931, would end in tragedy, the aircraft suffering a wing failure and rolling into the ground, killing Bayles. Two reproductions of the Gee Bee Z have been constructed. One, a faithful reproduction of the original aircraft, was constructed by Jeff Eicher and Kevin Kimball of Mount Dora, Florida, and is housed in the Fantasy of Flight museum
