Piel CP-10 Pinocchio
The Piel CP-10 was a post-war French sports aircraft in the Pou du Ciel tradition and was the first design from Claude Piel to fly. Design and development The CP-10 Pinocchio was the first of Claude Piel's long line of light aircraft designs. Despite the common name, it was completely different to his second design, the CP-20 Pinocchio. Built by Piel and Roger Holleville, the CP-10 was a Pou du Ciel style, single seat tandem-wing aircraft, powered by a Mengin B flat-twin engine mounted in the nose with its cylinder heads exposed for cooling and driving a two bladed propeller. The larger, forward wing was mounted above the flat sided fuselage on each side by two pairs of short, inverted-V struts from the fuselage to the wing rotation axis. The angle of incidence was controlled from the open cockpit by long rods from the lower fuselage to the wing underside near the trailing edge. The shorter span rear wing was mounted on top of the fuselage immediately behind the cockpit. ...

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, elevator (aircraft), elevators on the tailplane controlling Aircraft principal axes, pitch, and the rudder on the fin controlling Aircraft principal axes, 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. A sharp trailing edge is always employed in an airfoil. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerof ...

Aircraft First Flown In 1948
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, such as ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental aircraft, Experimental under Federal Aviation Administration, FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on m ...

Tandem-wing Aircraft
image:qac.quickie.q2.g-bspa.flying.arp.jpg, QAC Quickie Q2 A tandem wing is a wing configuration in which a flying craft or animal has two or more sets of wings set one behind another. All the wings contribute to lift (force), lift. The tandem wing is distinct from the biplane in which the wings are stacked one above another, or from the canard (aeronautics), canard or "tail-first" configuration where the forward surface is much smaller and does not contribute significantly to the overall lift. In aviation, tandem wings have long been experimented with, but few designs have ever been put into production. Tandem wings in nature occur only in insects and flying fish, although in the past there have been tandem-wing flying reptiles. Design principles A tandem wing wing configuration, configuration has two main wing planes, with one located forward and the other to the rear. The difference is greater than the wing chord, so there is a clear gap between them and the aircraft centre ...

1940s French Sport Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday 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 * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * 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. Asia * Battle of Yan Province: Warlords Cao Cao and Lü Bu fight for control over Yan Province; the battle lasts for over 100 days. * First year of the ''Xingping'' era during the Han Dynasty in ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulics, hydraulic device designed to absorb and Damping ratio, damp shock (mechanics), shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically thermal energy, heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in Pneumatic cylinder, air cylinders, the hot air is usually exhausted to the atmosphere. In other types of ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect. Some unusual land ...

Balanced Rudder
Balanced rudders are used by both ships and aircraft. Both may indicate a portion of the rudder surface ahead of the hinge, placed to lower the control loads needed to turn the rudder. For aircraft the method can also be applied to elevator (aircraft), elevators and ailerons; all three aircraft control surfaces may also be mass balanced, chiefly to avoid Aeroelastic flutter, aerodynamic flutter. Ships A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection. A degree of semi-balance is normal to avoid rudder instability i.e. the area in front of the pivot is less than that behind. This allows the rudder to be moved with less effort than is ne ...
