2. Downforce - Wikipedia

   en.wikipedia.org/wiki/Downforce

   The aspect ratio is the width of the airfoil divided by its chord. If the wing is not rectangular, aspect ratio is written AR=b 2 /s, where AR=aspect ratio, b=span, and s=wing area. Also, a greater angle of attack (or tilt) of the wing or spoiler, creates more downforce, which puts more pressure on the rear wheels and creates more drag.

3. Aspect ratio (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Aspect_ratio_(aeronautics)

   Aspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing ...

4. Formula One tyres - Wikipedia

   en.wikipedia.org/wiki/Formula_One_tyres

   Formula One. The 2023 Pirelli tyres include (from left to right) the three slicks – called the softs, mediums, and hards – intermediates, and full wets. Formula One tyres are specialised racing tyres designed for use on a Formula One car. Tyres play a crucial role in the car's performance, affecting grip, handling, and overall speed.

5. Formula One car - Wikipedia

   en.wikipedia.org/wiki/Formula_One_car

   Such an extreme level of aerodynamic development means that an F1 car produces much more downforce than any other open-wheel formula; Indycars, for example, produce downforce equal to their weight (that is, a downforce:weight ratio of 1:1) at 190 km/h (118 mph), while an F1 car achieves the same at 125 to 130 km/h (78 to 81 mph), and at 190 km ...

6. Chord (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Chord_(aeronautics)

   Chords on a swept-wing. In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge. [1][2] The point on the leading edge used to define the chord may be the surface point of ...

7. Lift-induced drag - Wikipedia

   en.wikipedia.org/wiki/Lift-induced_drag

   For a given wing area, a high aspect ratio wing will produce less induced drag than a wing of low aspect ratio. [16] While induced drag is inversely proportional to the square of the wingspan, not necessarily inversely proportional to aspect ratio, if the wing area is held constant, then induced drag will be inversely proportional to aspect ...

8. Condor Shoestring - Wikipedia

   en.wikipedia.org/wiki/Condor_Shoestring

   The shoestring differed in approach to the 66 sq ft wing limitation, choosing a longer high aspect ratio tapered wing compared to the stubby wings of others. [1] The original aircraft (registered N16V ) was extensively rebuilt in 1965 and 1974, and by that time had won fourteen first places, three second places and four third places.

9. Oswald efficiency number - Wikipedia

   en.wikipedia.org/wiki/Oswald_efficiency_number

   The Oswald efficiency is defined for the cases where the overall coefficient of drag of the wing or airplane has a constant+quadratic dependence on the aircraft lift coefficient. where. For conventional fixed-wing aircraft with moderate aspect ratio and sweep, Oswald efficiency number with wing flaps retracted is typically between 0.7 and 0.85 ...
