Aerospace Engineering Elements are not limited to a particular field. It is very vast that nobody can even image and compare with other branch. It not only include aerodynamic, but also include mechanical, electrical, machine, civil and much more. Because of the complexity and number of disciplines involved, aerospace engineering is carried out by teams of engineers. Basis of most of these elements lies in theoretical physics, such as fluid dynamics for aerodynamics or the equations of motion for flight dynamics. Here some of the Aerospace Engineering Elements are mentioned with their introduction.
Aerospace Engineering Elements
Some of the Aerospace Engineering Elements are as follows:
- Aeroacoustics – the study of noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces.
- Aeroelasticity – the interaction of aerodynamic forces and structural flexibility, potentially causing flutter, divergence, etc.
- Aircraft structures – design of the physical configuration of the aircraft to withstand the forces encountered during flight. Aerospace engineering aims to keep structures lightweight and low-cost, while maintaining structural integrity.
- Avionics – the design and programming of communication systems on board an aircraft or spacecraft and the simulation of systems.
- Astrodynamics – the study of orbital mechanics including prediction of orbital elements when given a select few variables.
- Control engineering – the study of the dynamic behavior of systems and designing them, so that their dynamic behavior is desirable (with minimum error). This applies to the dynamic behavior of aircraft, spacecraft, propulsion systems, and subsystems that exist on aerospace vehicles.
- Electro technology – the study of electronics within engineering.
- Flight test – designing and executing flight test programs in order to gather and analyze performance, handling qualities data and certification requirements.
- Fluid mechanics – the study flow of fluid around objects. Specifically aerodynamics concerning the flow of air over bodies such as wings or through objects such as wind tunnels.
- Materials science – related to structures, aerospace engineering also studies the materials. New materials with very specific properties are invented, or existing ones are modified to improve their performance.
- Mathematics – in particular, calculus, differential equations, and linear algebra.
- Noise control – the study of the mechanics of sound transfer.
- Propulsion – the energy to move a vehicle through the air (or in outer space) provided by internal combustion engines, jet engines, or rockets. A more recent version to this is electric propulsion and ion propulsion.
- Risk and reliability – the study of risk and reliability assessment techniques involved in the quantitative methods.
- Software – the implementation of computer software for aerospace applications, including flight software, ground control software, test & evaluation software, etc.
- Statics and mechanics – the study of movement, forces, moments in mechanical systems.
Apart from this some of the other Aerospace Engineering Elements include thermal control, equation of motion etc.
Aerospace Engineering History
Aerospace Engineering is the field of engineering which deals with development of Aircraft and Spacecraft. Aerospace Engineering History begins in the 19th century with the first flight of Wilbur and Orville Wright in 1903. It is further divide into two branch Aeronautical Engineering which involves powered than light aircraft such as gliders, fixed wing airplanes, jets and helicopters, inside earth’s atmosphere and Astronautical Engineering which involves design and development of spacecraft outside of earth’s atmosphere. All information regarding Aerospace Engineering History and Facts is given here in this page.
Aerospace Engineering History and Facts
Where do the idea come from?
All early concepts and thinking of human flight comes from the imitation of birds.
Origin of Aerospace Engineering
The origin of aerospace engineering can be traced back to the aviation pioneers around 19th century. Many of the Scientist read birds characteristics and gave their concepts about aerospace engineering. But nobody succeeded in their theory, later on two brothers Orville and Wilbur Wright made this possible. And the first successful flight in Aerospace History recorded on 17 December 1903. All credit goes to Orville and Wilbur Wright. The Wright brothers gave the concepts of lift, weight, drag and thrust from a suitably powerful engine, and three-axis control of pitch, roll and yaw.
The stepping stones involved in the Aerospace Engineering History and Facts to controlled manned heavier than air flight are as follows
- Leonardo the Vinci comes with Ornithopter and made more than 500 sketches of his design from 1486 to 1490. However he was unsuccessful over his attempt.
- The Montgolfier hot air ballon floats over Paris on 21 November 1783. It is the first thing which lifted a human being for some time.
- Sir George Cayley gave the concept of fuselage, a fixed wing and horizontal and vertical tails in 1799. He is the first person who proposed separate mechanism for the generation of lift.
- The first two powered flights achieved by Felix Du Temple in 1874 and Alexander F. Mozhaiski in 1884. But they failed to control this and withdraw their hands.
- Otto Lilienthal designs the first fully successful gliders in Aerospace Engineering History. From 1891 to 1896, he achieves more than 2000 successful gliders flights. But he died in a glider crash.
- Samuel Pierpont Langley achieved the first successful unmanned heavier than air flight and made Aerospace Engineering History in 1896. However he was unsuccessful in manned flight 9 days before Wright Brothers.
- Orville and Wilbur Wright made the first controlled, sustained, powered, heavier than air manned flight in Aerospace Engineering History. They both made their first successful flight on 17 December 1903.
- The development of aeronautics than takes off exponentially after the Wright Brothers public demonstration in Europe in 1908.
Aerospace Engineering disciplines include aerodynamics, propulsion, avionics, materials science, structural analysis and manufacturing. Aerospace engineering, particularly the astronautics branch, is often referred to as “rocket science”
