The German professor Hugo Junkers was seriously interested in doing away with drag-inducing struts and rigging around the start of World War I, and by mid-1915 his firm had designed the Junkers J 1 all-metal "technology demonstrator" monoplane, possessing no external bracing for its thick-airfoil cantilever wing design, which could fly at just ...
The drag strut member, used to transfer the load to the shear walls or frames; the chord, used to resist the tension and compression forces that develop in the diaphragm since the collector is usually incapable of handling these loads alone
A MacPherson strut combines the primary function of a shock absorber (as a damper), with the ability to support sideways loads not along its axis of compression, somewhat similar to a sliding pillar suspension, thus eliminating the need for an upper suspension arm. This means that a strut must have a more rugged design, with mounting points ...
The NACA cowling enhanced speed through drag reduction while improving engine cooling. The cowling consists of a symmetric, circular airfoil that is wrapped around the engine. In a normal planar airfoil, like a wing, the difference in airspeeds, and their associated changes in pressure, on the top and bottom surfaces, enhances lift.
Strut-to-wing and strut-to-fuselage junctions Strut end fairings reduce drag at these junctions. [citation needed] Tail cones Tail cones streamline the rear extremity of a fuselage by eliminating any base area which is the source of base drag. Wing root Wing roots are often faired to reduce interference drag between the wing and the fuselage.
Tailless delta: a classic high-speed design, used for example in the Dassault Mirage III series. Tailed delta: adds a conventional tailplane, to improve handling. Used on the Mikoyan-Gurevich MiG-21. Cropped delta: wing tips are cut off. This helps avoid tip drag at high angles of attack. The Fairey Delta 1 also had a tail. At the extreme ...
Relying partly on electric power might reduce specific fuel consumption (SFC) compared to a standard turbine-only design (turbofan or lower-consumption turboprops). SUGAR Volt is designed with a long, braced, high aspect ratio wing that decreases induced drag due to lift. The wings of SUGAR Volt would enable it to take off in a shorter distance ...
On these applications the drag link connects to the steering arm located at the wheel. In some Jeep applications, the drag link will swing from right to left on the vehicle and will connect to the steering arm at the wheel. Drag links can be a solid one-piece design or an adjustable design. Many drag links have replaceable or rebuildable ends." [3]
