Why did the Red Baron have 3 wings?
Yet in Fokker’s hands, three wings, aided by fat airfoils and low weight design, supplied superb maneuverability. His design approach is fully detailed in the book. The special tactics employed by the Red Baron were crucial to the success of his Three Wings, in particular those downplaying speed and stressing agility.
Why do biplanes have two wings?
Biplanes were the original aircraft design in aviation to provide a lightweight yet sturdy structure. Newer materials and designs are much stronger and can be built with one wing. Having two wings stacked on top of each other also meant that the wings have twice the area so this allowed for the span to be shorter.
Why are high wing planes stable?
High wing aircraft are more stable because of their lower center of gravity CG) , relative to the wing. The gravity hangs underneath the lift of the wings. Conversely, when the center of gravity is above the wing, there is an unstable tendency to flip around try to go where the CG is below and no longer above.
Why are delta wings used?
The delta wing offers advantages in structural integrity and both high-speed and low-speed flight. Because of the wing’s large surface area compared to its span, it can be built stronger and stiffer, and also has a greater internal volume for fuel storage.
What was the point of Triplanes?
The triplane arrangement may be compared with the biplane in a number of ways. A triplane arrangement has a narrower wing chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift.
Why did old planes have multiple wings?
The main reason for having multiple wings in the initial years of the aviation was the lack of availability of materials with sufficient strength. The main advantage of the biplane is that the wings could be shorter for a given lift.
Is low wing better than high wing?
High-wing airplanes give pilots and passengers a better view of the ground below the aircraft. This is especially true of 4-seat and larger planes, where there is less a chance of a wing blocking your view. Low-wing airplanes allow for a better view above the plane thanks to the wings being below the fuselage.
Why do fighter jets use delta wings?
Advantages: Delta wings have a long root chord and therefore can have a thick main spar while retaining a low thickness-‐to-‐chord ratio. They also have larger wing area than trapezoidal wings with the same aspect ratio. This means low wing loading even during maneuvers.
Why do fighter jets have delta wings?
The main wing of the XB-70 is a delta wing to keep the take-off and landing speeds relatively low and offers the best compromise of low and high speed characteristics. Also, the wing tips could be deflected downwards to improve directional stability at supersonic speed and to improve L/D by using the waverider effect.
How many planes were in the US during WW2?
World War II Aircraft World War II witnessed tremendous growth in the size of American military aviation, from about 2,500 airplanes to nearly 300,000 by the war’s end.
What engines were used in World War II fighter jets?
The fighter needed higher power per unit of weight per unit of frontal area, and initially received the supercharged liquid-cooled inline engine such as the Rolls-Royce, Allison, or Daimler Benz. Later, when cooling and cowling aerodynamics were improved, air-cooled radials were often used, as in the Republic P-47 and Focke Wulf Fw 190.
Why did World War II change the engine design?
Many of the engines which would see service in World War II started production in 1935. Engine design was driven by the push for altitude capability, where thinner air placed great emphasis on the supercharger. This push for power via increased supercharger pressure ratios and engine compression ratios also required improvements in fuel quality.
How did aircraft speed increase during World War II?
It is noteworthy that with very few exceptions, almost all improvements in aircraft speed and load-carrying capability during World War II came from increased engine power and not from aerodynamic, structure, or system improvements in airframes. In turn, engine power increases came mainly from improvements in fuel and superchargers.
