Antonio Cañete Heredia was a Spanish military pilot and engineer who in the early 1920s designed and built a successful glider flying boat, the Gaviota (Gull). Emboldened by the experience took the logical next step. His Pirata (Pirate) or “Hidro Antonio Cañete de Reconocimiento” (HACR) was conceived as a military recon parasol wing, single-engined flying boat. Due to the crude state of metallurgy industry in Spain, Cañete was forced to use galvanised iron in the main structure; wood and fabric was employed in the rest.
Powered by a locally built 450 hp Elizalde-Lorraine, the Pirata made its maiden flight in the summer of 1927 with its designer on board as an observer. During its tests the Pirata proved to be a sound design, but it was not to be. Lack of money -the usual Spanish curse- or the already available Dornier Wal sealed its possible future. Only this prototype was built.
It was undeniably a slick effort.
Designed by a Mikoyan OKB-155 design team headed by Gleb Evgeniyevich Lozino-Lozinskiy, the Spiral (aerospace system) was a Soviet project created as a military orbital spaceplane in response to the American Boeing X-20 Dyna-Soar. Ironically by the time the design was started (1965) the American project was already cancelled so after four years it was also stopped….to be initiated in the middle 1970s as a possible answer to the Space Shuttle. The project reached the hardware state with sub-scale orbital test models and a manned test vehicle to explore low-speed behavior, the MiG-105.
To no avail, in the end the Spiral was cancelled when the Soviet authorities decided to follow closely the American Space Shuttle concept. The Buran project was the result.
This clever GIF gives us an idea of its audacious configuration. The Spiral spaceplane with its attached liquid fuel booster stage seats atop hypersonic jet mothership designed by the Tupolev OKB. That reusable mothership acted as the complex’s first stage which launched Spiral and its booster at high altitude.
Designed by René Riout, the Riout 102T Alérion was without doubt one of the most advanced ornithopters ever built. Built in 1937, its sophistication was a wasted effort; like almost all aircraft of this type, the Alérion was a non-flyer. Luckily, this superb contraction is still with us today, lovingly preserved at the Musée Régional de l’Air d’Angers.
Four wings and four wheels. Jolie Libelulle, n’est ce pas?
In 1922 the United States Army Air Service (USAAS) put the requirement for a racing aircraft design to take part in the already famous Pulitzer Trophy Race. The Thomas-Morse company answered with this advanced all-metal parasol monoplane powered by a 600hp Packard 1A-2025 engine. Two R-5s were produced and both took part in the 1922 Pulitzer. With not very bright results: they finished last and next-to-last. The USAAS found nevertheless the right usage for them though. They were destroyed during static structural tests.
Unmistakable the style of Douglas Rolfe in this drawing. Part of Rolfe’s “Air Progress” series of the 1950’s, later reedited in this marvellously abused book. By the way, the information is wrong; it corresponds to the US.Navy Thomas-Morse MB-7 racer of 1921.
“Will “Whirling Leaf” Revolutionize Flying?”
The people of “Popular Science” were still wondering in 1922 about a hopeless 1911-15 aircraft concept.
Lovely artwork. The Papin-Rouilly Gyroptère never flew higher.
The bird face like rear end of the startling Sea Dart. Its “beak” has a set of dive brakes which also doubled as water brakes and as a water rudder while on the sea surface. Three in one.
One of the four prototypes built (Bureau Number 135765) on display at the Florida Air Museum.
In 1945 even if the war had devastated Fokker company’s Schipol plant, the Dutch Fokker company was determined to restart its own aviation activities. Back to the basics. The design team came up with the idea of a very simple elementary trainer which could be produced employing the simple tooling available while the company was being rebuilt. The S.11 prototype had its maiden flight in 1947 and was soon in production for the Royal Netherlands AF. A few other air forces soon followed. The type was also produced under licence in Italy and Brazil. The later produced its own local variants, one of them with a tricycle undercarriage: the S.12.
The pedestrian Instructor and the superb S.14 Machtrainer prototype. With this pair Fokker was able to offer air forces a neat training package from primary to jet. Only the Dutch took it.
