Kayaba Ku-3
The Kayaba Ku-3 was a glider built in Japan in 1941 to investigate the possibilities of tailless aircraft. Building on the success of the Ku-2 design of the previous year, the Ku-3 was a substantially larger aircraft with several novel features. The small vertical fins of the Ku-2 were abandoned, leaving the Ku-3 with no vertical control surfaces. The crescent wing had three pairs of control surfaces on the trailing edge The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. .... The outer, less-swept wing sections had a greater dihedral than the inner sections. The prototype crashed after 67 flights, when the test pilot was unable to recover from a spin. References * 日本飞翼的短暂研究 {{Japanese Army Glider Designation System Kayaba aircraft 1940s military gli ...

Kayaba Ku-2
The Kayaba Ku-2 (''萱場 2型無尾翼滑空機'') was a glider built in Japan in 1940 to investigate the possibilities of tailless aircraft. It was developed as part of an Imperial Japanese Army contract that had been offered to designer Hidemasa Kimura following the successful flights of his HK-1 tailless glider over the previous years. Developed with the help of the Kayaba Industry is a Japanese, Tokyo-based automotive company. Among KYB's main products company are shock absorbers, air suspensions, power steering systems, hydraulic pumps, motors, cylinders, and valves. It is one of the world's largest shock absorber m ...'s chief designer Shigeki Naito, the Ku-2 had a swept wing with two vertical fins at the end of the wings. The Ku-2 flew 262 test flights between October 1940 and May 1941 before being damaged beyond repair in a crash.

Crescent Wing
The crescent wing is a fixed-wing aircraft configuration in which a swept wing has a greater sweep angle on the inboard section than the outboard, giving the wing a crescent shape. The planform attempts to reduce several unpleasant side-effects of the swept wing design, notably its tendency to "pitch-up", sometimes violently, when it nears a stall. Basic concept As an aircraft enters the transonic region close to the speed of sound, the acceleration of air over curved areas can cause the flow to go supersonic. This generates a shock wave and creates considerable drag, known as wave drag. The increase in drag is so rapid and powerful that it gives rise to the concept of a sound barrier. The speed at which this effect becomes noticeable, known as ''critical mach'', is based on the rate of curvature on the upper and lower surfaces; airfoils with greater curvature will have a lower critical Mach speed and thus suffer more heavily from wave drag. A wing designed for good transonic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Control Surfaces
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, but once aloft, the aircraft proved uncontrollable, often with disastrous results. The development of effective flight controls is what allowed stable flight. This article describes the control surfaces used on a fixed-wing aircraft of conventional design. Other fixed-wing aircraft configurations may use different control surfaces but the basic principles remain. The controls (stick and rudder) for rotary wing aircraft (helicopter or autogyro) accomplish the same motions about the three axes of rotation, but manipulate the rotating flight controls (main rotor disk and tail rotor disk) in a completely different manner.

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerofoil on the circulation.”Batchelor, G. K. (1967), ''An Introduction to Fluid Dynamics'', p.438, Cambridge University Press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1940s Military Gliders
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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 * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.
