Airplanes

By: Alex Duda

The Basics

Airplanes work on the principal of lift, which is called bernoulis principal or the bernouli effect. This principal says that when there is low pressure and high pressure the high pressure will force air up to equalize the pressures. This is how airplanes fly. The wing shape is flat on the bottom and curved on the top. the air on the bottom remains the same pressure as before, however the air on top has to mave faster to catch up with the air on the bottom there for causing low pressure and causing the wing to rise from the air rushing up to equalze the pressure.

This is the general shape of an airfoil or wing, with air passing over it. Designs can very widely by length width thickness and distance.

How Airplanes Work

Airplanes work on the principal of lift. For power airplanes use 3 main types of engines. Turboprop, Piston, and jet. Passengers that have ever Traveled on a Airline have probably ridden on a jet. Jets are most common, and best for airlines because they have a high cruise speed. And good efficiency on long ranges. Some airlines operate turboprops for shorter commuting flights. Therese aircraft offer short takeoffs and landings so they can fly into smaller airports. Piston aircraft are not operated by any airline because of short range and slow speed as well as lack of performance at high altitude. Piston aircraft are mainly operated by the General Aviation community. Therese are the pilots that operate out of small airports. An airplane is steered up down left and right by control surfaces. Therese are small parts of the wings and tail that are hinges so they can move. They are connected to the control stick or wheel by cables on smaller aircraft and wires on bigger fly by wire aircraft when moving the stick sends a signal telling the motor to turn.

Learning to fly

The first step to learning to fly is to take a discovery flight in a local fight school. This will run between 100 and 260 dollars depending on the school. This flight will last an hour and will faramalize you with all the components of the aircraft as well a basic manuvers. The next step is full in flying lessons. An hour of flying lessons runs about 200 dollars while " ground school" will run at about 15 dollars an hour. Ground school is when pupils discuss things like weather and flight planning while on the ground. Ground school is a lot cheaper than flight time. There are three types of ratings one can acheive rather easily. The first and easyiest to get is sport pilot which comes at 10 hours but you are limited to flying under 10000 feet and and in the daytime. Recrational pilots are limited to flying in us airspace as well as an aircraft under 180 hp and 4 seats maximum. Private pilots are limited to flying in visibilites over 3 miles and any plane less than 200 hp

Avation accomplishments

Avation over the years has had many accomplishments. Most people have heard of the Wright Brothers and Ameila Earheart. Earheart dissapered over the south pacafic in 1937 while attempting to fly around the world. The wright brothers were the first pioneers of flight. They hold the first flight with the wright flyer in 1903. Even though there is lots of avation accomplishhments there also is lots of tradgdeys such as 9/11 when two planes brought down the twin towers in New York City. There has also been many other accomplishments such as the invention of the jet engine in 1942 and the release of the cessna 172 which is augrublgy the most ever produced plane ever with 1 at almost every airfield. The 172 is also a great trianing airplane. Avation is always growing and always changing. There always be new accomplishments.
