In [[aviation]], a '''planform''' is the shape and layout of a [[fixed-wing aircraft]]'s fuselage and wing. Of all the myriad planforms used, they can typically be grouped into those used for [[low-speed flight]], found on [[general aviation]] aircraft, and those used for [[high-speed flight]], found on many [[military aircraft]] and [[airliner]]s.
 
The '''planform''' may also refer to the projected area of the wing. From a top view perspective, one can extend the lines from the leading and trailing edges on the left and right side of the fuselage until they meet at the centerline of the aircraft. The area of the wing along with this projected area is commonly referred to as the planform area, <math> S_{ref}</math>.  It is used as a [[Nondimensionalization|non-dimensionalization]] parameter.

==Low-speed==
[[Image:spitfire mark19 ps853 planform arp.jpg|thumb|upright|A [[Supermarine Spitfire|Spitfire]] built in 1945 shows off its elliptical planform]]
 
The primary concern in low speed flight is the [[aspect ratio (wing)|aspect ratio]], the comparison of the length of the wing measured out from the [[fuselage]], ''[[wingspan]]'', compared to the length from front to back, ''[[chord (aircraft)|chord]]''. Wings with higher aspect ratios, that is, wings that are longer and skinnier, have lower [[drag (physics)|drag]] for any given amount of [[lift (force)|lift]] than a wing of the same area that is shorter and fatter. This is due to an effect known as [[induced drag]], caused by airflow around the tip of the wing. As the size of the tip decreases compared to the wing's overall size, the magnitude of the induced drag is reduced.
 
This is why designers of [[Glider (sailplane)|gliders]], who want a high [[lift to drag ratio]], use very long and skinny high aspect ratio wings and [[Wingtip device|winglets]]. At higher speeds, however, different forms of drag become more prominent, meaning that the large aspect ratio wings found on gliders become very inefficient. Another issue is strength; it is harder to build a longer wing with sufficient stiffness than a short one.
 
There are other ways to reduce induced drag, mostly by changing the shape of the wing to reduce the size of the tip. The [[elliptical wing]] found on the [[Supermarine Spitfire]] and [[Republic P-47]] is the most efficient, but difficult to build. A practical compromise is to taper the wing towards the tip, a feature that can be found on almost all modern aircraft (including gliders).
 
==High-speed==
[[Image:Delta-Dart-DF-ST-85-09772.JPEG|thumb|left|The delta-winged [[F-106 Delta Dart]]]]
 
At higher speeds nearing the [[speed of sound]], a new form of drag appears:  [[wave drag]]. Wave drag is considerably more powerful than induced drag, and must be avoided at all costs to improve performance. Doing so demands a wing that is as thin as possible, with a slowly changing profile over a wide chord. Of course, this is basically the opposite goal to low speed wings, which presents a problem.
 
Just as on the lower speed designs, making an ideal high speed planform is difficult for practical reasons. In this case, a very thin wing makes it difficult to use the internal room to store fuel and landing gear, makes the wing far less stiff torsionally, and causes increased induced drag when flying slower.
 
Solutions to this problem come in many forms, notably the use of the [[swept wing]] and [[delta wing]], both of which avoid the [[shock wave]] at the leading edge. Other designs make the wing as thin as possible, leading to designs like the [[F-104 Starfighter]].

In a web based search, you can see that used tractor tires are used to supply tires for vintage farm gear as properly. Many sellers of used tires promote vintage tires as well as tires for extra modern agricultural gear. Maintaining vintage farm equipment has long been a favourite hobby of collectors and of households who have owned these farm implements for a few years. The presence of the vintage equipment on the household farm provides continuity and a way of historical past to the family possessing it.

Not like conventional automobiles golf carts aren't tracked so there's no means of telling the sum of damage the cart sustained with the previous proprietor. Many carts are utilized for other functions and akin to multi unit development complexes, schools, and maintenance depots for any different types of trades. Several will be discovered used and abused and infrequently look rough and properly broken. These aren't apt to be the very best decisions for ones personal golf wants.
