A fan from a Rolls-Royce RB211 turbofan engine, with its spinner visible at the centre of the fan blades.. The first spinners were fitted to aircraft in the early 1910s, originally to reduce drag caused by the large-diameter rotary engines of that era, and also were prominent on World War I-era aircraft, like the Morane-Saulnier N French monoplane fighter, and for the Central Powers, Robert ...

A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit, and greater than 1 is a hyperbola. The term derives its name from the parameters of conic sections, as every Kepler orbit is a conic section.
Fox is a brevity code used by NATO pilots to signal the simulated or actual release of an air-to-air munition or other combat function. Army aviation elements may use a different nomenclature, as the nature of helicopter-fired weapons is almost always air-to-surface.
A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning. In the UK, Ireland, Australia, and New Zealand spanner is the standard term. The most common shapes are called open-ended spanner and ring spanner.
The wing root fairing of an American Aviation AA-1 Yankee. An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag. [1]These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.
An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
