Yakovlev Yak-18T
The Yakovlev Yak-18T () is a four- or five-seat fully aerobatic utility aircraft developed by Yakovlev. Introduced to train Aeroflot pilots, it has gained some popularity as a sportplane both inside and outside the former USSR. It is powered by a 268-298 kW (360-400 hp) Vedeneyev M14P radial engine, and is designed for stresses of +6.48/-3.24 ''g''. Design and development All the Yak-18 and Yak-18T have in common is the model number. The Yak-18T is a unique design, despite its nomenclature. The 18T was designed in the late 60's, as a civilian aircraft. The aircraft has a nosewheel, is a four- or five-seater, and has a nine-cylinder 360 hp radial. The Yak-18T shares systems with the Yak-50/ 52 family. These aircraft all have the 265 kW (355 hp) Vedeneyev M14 nine-cylinder radial engine as well as the same underlying compressed-air system for engine starting, brakes, undercarriage and flaps. The propeller, avionics and other parts are also shared. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piper Saratoga
The Piper PA-32R is a six-seat (or seven-seat), high-performance, single engine, all-metal, fixed-wing aircraft produced by Piper Aircraft of Vero Beach, Florida. The design began life as the Piper Lance, a retractable-gear version of the Piper Cherokee Six. Later models became known by the designation Piper Saratoga. The primary difference between the Lance and early Saratoga is the development of a tapered wing on the Saratoga, replacing the "Hershey bar" wing on the Lance that was a carryover from the Cherokee Six. Later Saratoga models provided updated/improved avionics, engine and interior touches but retained the same airframe design. Production of the Saratoga was discontinued in 2009. The Saratoga competed for sales with the Beechcraft Bonanza, Mooney M20, Cirrus SR22, Cessna 210, and Cessna 350. Development Until 1972, when the assembly line was destroyed in a flood, the Piper PA-24 Comanche, Comanche was Piper's luxury, high-performance single. Afterwards, Piper ...

Aircraft First Flown In 1967
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970s Soviet Civil Utility Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...
