Designers at Armstrong-Whitworth took the sonic area rule a step further in their proposed M-Wing, in which the wing was first swept forward and then to the rear. This allowed the fuselage to be narrowed in front of the root as well as behind it, leading to a smoother fuselage that remained wider on average than one using a classic swept wing.
The Dymaxion map projection, also called the Fuller projection, is a kind of polyhedral map projection of the Earth's surface onto the unfolded net of an icosahedron.The resulting map is heavily interrupted in order to reduce shape and size distortion compared to other world maps, but the interruptions are chosen to lie in the ocean.
The Avro Canada CF-105 Arrow was a delta-winged interceptor aircraft designed and built by Avro Canada.The CF-105 held the promise of Mach 2 speeds at altitudes exceeding 50,000 feet (15,000 m) and was intended to serve as the Royal Canadian Air Force's (RCAF) primary interceptor into the 1960s and beyond.
Bowls, also known as lawn bowls or lawn bowling, is a sport in which players try to roll their ball (called a bowl) closest to a smaller ball (known as a "jack" or sometimes a "kitty"). The bowls are shaped (biased), so that they follow a curved path when being rolled.
wrong bias: a bowl delivered where the biased side of the bowl has been placed opposite to the desired position for a given delivery. If a right handed player plays a forehand delivery, but has the biased side of the bowl on the right, the bowls bias will take an arc away from the intended target, and in most cases, outside the rink boundary.
Sectional charts are in 1:500,000 scale and are named for a city on the map. The Federal Aviation Administration (FAA) in the United States publishes over 50 charts covering the continental United States, Alaska, and Hawaii. Sectional charts are published by the National Aeronautical Navigation Services Group of the FAA.
Short mat bowls is played indoors, so it is an all-year sport that is not affected by weather conditions. Because the equipment is transportable and easy to set up, it is particularly appropriate for locations that are also used for other purposes such as village halls, schools, and sports and social clubs; it is even played on North Sea oil rigs.
A World Aeronautical Chart (WAC) was a type of aeronautical chart used for navigation by pilots of moderate speed aircraft and aircraft at high altitudes in the United States. They are at a scale of 1:1,000,000 (about 1 inch = 13.7 nautical miles or 16 statute miles).
