Engineering Rocketry Robotics Aerodynamics Gliders Composites Aviation History Gliders are heavier-than-air aircrafts that do not depend on an engine. To stay aloft, the wings on a glider have to produce enough lift to balance out its weight. An example of a glider would be a paper airplane. The design, construction, launching and operation of rockets. A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. Rockets use thrust to be pushed foward while in flight. Chemical rockets are the most common
type of rocket used today. They are the
most common because they created exhaust
by combustion of rocket propellant. Unlike airplanes, gliders do not require an engine to stay aloft. Instead, gliders can use thermals, or streams of rising air, to maintain or even gain altitude. Most planes can glide if they lose their engines. Gliders are primarily used for recreational sports like hangliding and paragliding. The chinese were the first to use rocketry.
Soon after the whole enitire world was using
rocketry and during the cold war there was a
race between the soviet union and the united
states of america to reach the moon first with
a manned rocket. There were many early attempts at making gliders but information about them is lacking. Many of them were made out of feathers and ended in wrecks. Master of Aviation.....and pizza :) The Glide Angle is the angle of the gliders flight path relative to the horizon. It can be thought of as the measure of flying efficiency of a glider. When launching a rocket there are
multiple team members. There is the
launch team which is responsible for the
launching of the rocket and making sure the launch goes smoothly and no one gets hurt. The recover team is responsible for the safe recovery of the rocket and making any repairs to the rocket after it is launched. The observation team is responsible for the marking of the angle and height of the rocket when it is at its highest and recording the info. The design of a rocket all depends on
the center of gravity, center of pressure, nosecone, fins, recovery system. The center of gravity is the point where all forces are pushing down on the aircraft. The center of pressure is the point on a body where the total sum of a pressure field acts, causing a force and no moment about that point. The center of gravity must be in front of the center of pressure for the rocket to function properly. The other components of a rocket are up to the designer and all make the rocket good or bad. According to Random House Dictionary, "Aerodynamics is the branch of mechanics that deals with the motion of air and other gases and with the effects of such motion on bodies in the medium." The four forces on an airplane are thrust, drag, lift, and weight. Thrust and drag are in the horizontal plane while lift and weight are in the vertical plane relative to the aircraft. In order for a plane to fly the lift has to be equal to or greater than the weight and the thrust has to be greater than the drag to accelerate. Aerodynamic lift is the component of the aerodynamic forces acting on an airfoil that opposes gravity according to <thefreedictionary.com>. A simplified answer as to how lift is generated is that the pressure above the wing decreases while the pressure below the wing increases. This causes the airfoil to rise in relation to the airflow. In space the pressure is much greater than on earth due to the massive amount of area around the person. The tempertature is also much colder in space due to there being no atmosphere around you. We are very lucky to have the earth becasue it protects us from all of these things. Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is used in Aerospace Engineering many ways. There is the use of programming to fly UAV's, GPS and robots in general. Computer programming is the process of designing, writing, testing, debugging / troubleshooting, and maintaining the source code of computer programs. The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites Robotics are used many ways in
Aerospace Engineering, from GPS to just plain old robots that complete tasks and the most advanced form is UAV's or unmaned aircrafts. We have come a long way from when we used to have computers that took up whole rooms and now we can have a hand held GPS device that tells us where we are anywhere in the world A Brief History of Aerodynamics 1480 - 1500 - Leonardo de Vinci draws designs for helicopters, ornithopters, and parachutes.

December 17, 2003 - First Flight Centennial Celebration Early philosophers like Aristotle, Leonardo de Vinci, and Galileo made a few observations about aerodynamics but not much effort was spent studying aerodynamics pre 17th century. Although Leonardo de Vinci did publish "Codex on the Flight of Birds" in 1505 which mentioned that the center of gravity and the center of pressure do not coincide in a bird. Between the 18th and 19th centuries many experiments were done regarding aerodynamics. Sir George Cayley was the first person who identified lift, weight, thrust, and drag and there relationship. Francis Herbert Wenham created the first wind tunnel in 1871. Otto Lilienthal was the first person who to become highly successful with glider flights. Boyle's law describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. This is very important in space because the pressure and gas must stay proportional and keep you alive. Composite materials are engineered or naturally occurring materials made from two or more materials with significantly different physical or chemical properties which remain separate. In the early 20th century the Wright Brothers built and flew the first powered aircraft. Their flight proved and disproved many theories about aerodynamics, for instance Newton's drag force theory was proved incorrect. Since the Wright Brother's, there have been many advancements in planes and propulsion systems. Propulsion Systems The construction of composites can be done many
ways. The most common and easiest way to do this
is to apply resin to one side of the the material and
then place another on top of it. This will then create
a bond between the materials and they will bascially
become on material and this will make it much
stronger in the end. These materials are never one
material they are just two pieces bonded together. Propellers act like a turbine in that they use rotary motion to generate thrust. Modern propellers are made of composite materials, but they can be made of laminated wood or metal. We have composites in the world today because they are very strong and lightweight, they
are commonly used in airplane wings because they are lightweight and because of their
strength. One of the most common composites is carbon fiber. It is being used in more and
more things today in the world just because of how strong it is and how light it is. THE MOST INTERESTING MAN IN THE WORLD A turbo jet is the oldest kind of jet engine and was developed in the late 1930s. Turbo jets are made of an air intake, a compressor, a combustion chamber, a turbine, and a nozzle.
Turbo jets take in air, compress it and adds fuel to it which is ignited before the air exits through the nozzle. Ramjets use an aircraft's forward motion to provide thrust. They compress the air, without using a rotary compressor, and then provide continuous combustion to the air before it is sent out the nozzle. Ramjets can operate up to mach 6, however they cannot propell an aircraft that isn't moving. A varient of the ramjet is the scramjet which is modified so that combustion takes place at supersonic air flow. This lets scramjets operate at higher speeds than ramjets. See Rocketry.
