strengthened by stiffening-elements arranged at extremely small distances apart, so as to obviate the necessity of placing the material under initial .tension. Figs. 3 and 4 are diagrammatic transverse and longitudinal sections showing the inven- .tion applied to an aeroplane wing which comprises an...

school teacher and engineer (again). As an engineer I have been mainly involved in structural testing of aircraft parts as well as complete aircraft, but I didn’t start flying until 2001. Since 2012 I have been flying my own home-built Sonex, which took me about 6 years to build ...
The propellers are designed for maximum efficiency, with an IE 1 rating, which means they convert electrical energy into mechanical energy with minimal loss. This efficiency is crucial for prolonged use and optimal performance in your DIY projects. **Ease of Use and Compatibility** These ...
For example, some parts are clearly not represented by any filter nor filter combination, as their AP is very low across all layers (e.g. 7.0 for aeroplane-engine, 3.6 for bike-chainwheel, 2.6 AP for person-foot, at layer 5 using the GA combinations). On other parts instead, the ...
The team's final design resembles a large, lightweight glider. The aircraft, which weighs about 5 pounds and has a 5-meter wingspan, carries an array of thin wires, which are strung like horizontal fencing along and beneath the front end of the plane's wing. The wires act as positively...
Fig. 3 shows a joint between the front spar, ribs and skin of an aeroplane wing, the spar comprising a thin metal web 9 and flanges 7 connected together by angle strips 8 soldered to both elements. Holes 15 may be formed in the strips 8 for the introduction of soldering material. ...
21, 1934. [Class 4] An aeroplane wing or like aircraft structure comprises a main rigid spar and an auxiliary rigid spar, the first mentioned spar being fixed at least at two points located in different horizontal planes and the second fixed at one point to the fuselage or the like, the...
Fig. 7 illustrates the manner in which an outer metal covering is applied to a wing using the ribs described, two ribs 17 and a portion of a spar 3 being shown. The covering consists of strips 18 of sheet metal extending in the direction of flight, each strip having flanges at its ...
Figs. 1 and 2 show a portion of a metal wing having an internal metal framework comprising front and rear spars 2, 3, and ribs 1 extending in the direction of flight. The upper and lower surfaces consist of strips of thin sheet metal, flanged at both edges, extending between adjacent ...
