of a leaf spring. In some cases complete collapsing is prevented by its own rigidity. The capsule is mounted inside a case. The case is fed with static pressure from aircraft static tube/ vent. As the aircraft climbs the static pressure in the case decreases allowing the spring to pull the capsule faces apart. If the aircraft descends the rise in pressure in the case compresses the capsule faces. The linear movement of the capsule face is magnified and transmitted via a system of gears and

There were many aircrafts in World War II‚ this is the history and the different types of aircrafts. The World War II aircrafts were a deadly weapon and there were many of them. These aircrafts pretty much make up the war. The attacks and battles in World War II mostly used aircrafts to attack enemies from the sky. The history of the aircraft goes way back. Manufacturers made many different aircrafts for many different purposes. World War II allies needed many aircrafts to win the war‚ and 100

Aircraft Design Project Introduction You have designed a launch vehicle to insert a satellite into orbit . You now need a means to transport that satellite from your factory to the launch site. A cargo jet aircraft is the most likely candidate‚ though it may have to be unusual in size and shape because of the weight and shape envelope of the satellite design. Speed is not critically important but range is. Since the aerospace industry has become truly an international business it would be advisable

The causes of these aviation accidents vary greatly depending on specific circumstances and problems that may develop during the flight process. Weather is one of the factors that can influence an aircraft accident in a number of ways. There are several weather factors that cause and contributed to aircraft accidents.
