Junkers Ju EF112 1:35



This design for a ground-attack aircraft was submitted to the RLM by Junkers in December 1942. The wings had a straight leading edge and the short fuselage was mounted high on top of the wing. Power was supplied by two Daimler Benz DB 603G piston engines (each developing 1460 horsepower). One engine was mounted in the nose pulling and one was mounted in the fuselage tail pushing, this had the advantage of providing the power of two engines but lowering drag by putting the engines in-line. An internal bomb bay beneath the cockpit could hold a single 500 kg (1102 lbs) bomb
There were two booms which attached to the bottom of the wing surfaces, they extended to the rear and contained the vertical tail assembly. A horizontal tail connected the booms at the rear. The main landing gear were located in the booms and retracted to the rear. The pilot sat in a cockpit located above the wing leading edge under a cnopy that would have provided good vision all around. Armament consisted of two MK 103 30 mm cannon with an option to carry four R 100 Bordraketen air-to-air rockets.
The RLM showed no interest in the Junkers Ju EF112 and rejected the project.

BV-38 Flying Wing 1:72






andy: "They're gonna fly it out of here. When that ark gets loaded we'll already be on that plane."

So begins one of the most harrowing fight sequences in cinematic history as Indy goes fist-to-fist with nazis while dodging the spinning propellers of an out-of-control flying wing and we are introduced to one of the most unique contrivances devised for the screen, the nazi flying wing.

The fictional flying wing prototype was designed by concept artist Ron Cobb who is listed as one of the production artists (although in the bonus material disc of the Indiana Jones box set, the design of the wing was attributed to Raiders of the Lost Ark Production Designer, Norman Reynolds). The inspiration for the wing was not from the many advanced tailess designs of the nazi plane designers like the Horton bros. but by an american flying wing prototype from the 1940s (although it was never mentioned, but I'm guessing the specific inspiration may have been one of Jack Northrop's early flying wing designs). The full-sized model was built by the Vickers Aircraft Company and shipped in pieces to the set in Tunisia where it was assembled on set. Although the action was all between Indy and the big nazi goon, the centerpiece of the sequence was the flying wing!

yup serious guys I fellin' love with this airplane since I watched the movie, after a long delay I finally decide to make one, just got the 3view from forbiddenplastic.com.

Papercraft del Curtiss P-40 M de los Tigres Voladores escala 1/72

Por , en 31 de enero de 2009

Quien no recuerda a los famosos “Tigres voladores” por la famosa película con John Wayne, aquel escuadrón que se enfrentó a los japoneses en China y obtuvo excelentes resultados derribando una gran cantidad de aviones enemigos comparado con sus pérdidas. Para aquella época existía mucha tensión en el pacífico, debido a Japón y sus ansias expansionistas, las tropas imperiales le habían puesto el ojo a China y hacia aya marcharon en 1937.

Curtiss P-40 de los Tigres Voladores en papel

Para entonces todavía no existía el P-40, pero de seguro se pensaba en su diseño; hacia 1938 la firma Curtiss lanza el experimental XP-40 y pronto empezó su producción, siendo enviado un escuadrón en apoyo de los nacionalistas chinos el cual no entró en combate hasta 1941 en que un grupo de “tigres” atacó una escuadrilla de bombardeo japonesa.

 

Se sabe por las estadísticas que derribaron más de 300 aviones enemigos, perdiendo sólo 12 aparatos. Uno de sus pilotos más famosos fue sin duda Gregory Boyington, al que seguramente recuerdan por su famoso libro ”Baa Baa Black Sheep”, en que cuenta la vida del VMF-124 en el pacífico y sus hazañas con el F4U Corsair.

Este avión tipo caza de un solo tripulante, tenía una longitud de 10.16 metros, 3.76 de altura y una superfie alar de 33 metros cuadrados. Su peso era de 2,812 kilogramos y cargado podía llegar hasta los 4,000 kilos. El motor era un Allison V-1710, de tipo lineal, el cual le propporcionada una potencia de 1,200 CV (superada en el Tipo M a 1,360 CV) y obtenía una velocidad de unos 552 km/h.

Esta aeronave estaba equipada con un excelente armamento compuesto por seis ametralladoras Browning calibre 12.7 mm.

El Curtiss P-40 M era un modelo con mayor potencia, equipado con un motor en V del tipo 1710-81 de 1,360 caballos de vapor. 600 de estos aparatos se entregaron a la USS Air Force; la RAF obtuvo unos 616 Kittyhawk Mk III, similares al P-40M, los cuales combatieron en Oriente Medio, enfrentándose contra el poderoso Messerschmitt Bf 109F.

Cessna O-2 Skymaster 1:48

The O-2 Skymaster (also known as the "Oscar Deuce" or "The Duck") is a military version of the Cessna 337 Super Skymaster utilized as an observation and forward air control (FAC) aircraft. The United States Air Force commissioned Cessna to build a military variant to replace the O-1 Bird Dog in 1966.

Design and development

As with the civilian version, the Skymaster was a low cost twin-engine piston powered aircraft, with one engine in the nose of the aircraft and a second engine in the rear of the fuselage. The push-pull configuration meant a simpler single-engine operating procedure due to centerline thrust compared to the common low-wing mounting of most twin engine light planes, and also allowed for a high wing, providing clear observation below and behind the aircraft. During the Vietnam War, the Skymaster was intended to be replaced in the forward air control (FAC) mission by the OV-10 Bronco, but the O-2A maintained a night mission role after the OV-10's introduction due to the OV-10's high level of cockpit illumination, rendering night reconnaissance impractical.[1] The O-2 was phased out completely after additional OV-10 night upgrades.[2][3]

The first O-2 flew in January 1967 and the plane went into production shortly thereafter, with the USAF taking delivery in March 1967. A total of 532 O-2s were built in two variants for the USAF by 1970. The O-2A served as a FAC aircraft with the 20th Tactical Air Support Squadron, while the O-2B was equipped with loudspeakers and a leaflet dispenser for use in the psychological operations (PSYOPS) role. Several USAF O-2 aircraft were later transferred to and operated by the former VNAF South Vietnamese Air Force.[3]
Following the Vietnam War, the O-2 continued to operate with both U.S. Air Force and Air National Guard units well into the late 1980s. Six former USAF O-2A airframes were also transferred to the U.S. Navy in 1983 for use as "range controllers" with Attack Squadron 122A-7 Corsair II at Naval Air Station Lemoore, California. These same aircraft were later transferred to Strike Fighter Squadron 125VFA-125), the F/A-18 Hornet FRS at NAS Lemoore, in 1986 for use in the same range control role.[4] (VA-122), the Pacific Fleet Replacement Squadron for the (
The six Navy O-2A's remained in this role until September 1990, when they were replaced by T-34C Turbo Mentor aircraft transferred from the Naval Air Training Command. Four of the Navy O-2A aircraft were retired and two of these became civil registered in October 1991. These two aircraft were flown in U.S. airshows performing a "Viet Nam Warbird COIN/FAC" routine during the 1990s. The routine debuted at the "Wings Over Houston" (Texas) airshow in October 1991.[citation needed]

Of the six USN aircraft mentioned above, two were transferred to the U.S. Army in late 1990.[4] O-2As had originally entered the U.S. Army's inventory in 1967 from USAF stocks and were augmented by the 1990 aircraft transfer from the U.S. Navy. Several disassembled USAF O-2s remain in storage at Davis-Monthan AFB, Arizona.[4] Two O-2As were used at Laguna Army Airfield, Arizona as part of testing programs carried out by the Yuma Proving Ground. These were retired in October 2010 and sent to a museum. source
