Aeronautics deals with the whole field of design, manufacture, maintenance, testing, and use of aircraft for both civil and military purposes. It involves the knowledge of aerodynamics, structural design, propulsion engines, navigation, communication, and oilier related areas.
Aerospace engineering is closely connected with aeronautics, but is concerned with the flight of vehicles in space, beyond the earth's atmosphere, and includes the study and development of rocket engines, artificial satellites, and spacecraft for the exploration of outer space.
Naval Engineering
Naval architects are engineers who design and supervise construction of ships. Ships must be designed and built so that they are safe, stable, strong, and fast enough to perform the type of work intended for them. A naval architect must be familiar with the variety of techniques of modern shipbuilding.
Marine engineering is a specialized branch of mechanical engineering devoted to the design and operation of systems, both mechanical and electrical, needed to propel a ship. Engineers in this field develop diesel engines and steam turbines that provide enough power to move the ship at the required speed.
Chemical Engineering
This branch of engineering is concerned with the design, construction, and management of factories in which the essential processes consist of chemical reactions. The task of the chemical engineer is to select and specify
the design that will best meet the particular requirements of production and the most appropriate equipment for the new applications.
Nuclear Engineering.
This branch of engineering is concerned with the design and construction of nuclear reactors. In addition to designing nuclear reactors that yield specified amounts of power, nuclear engineers develop the special materials
necessary to withstand the high temperatures and radioactivity. Nuclear engineers also develop methods to shield people from the harmful radiation produced by nuclear reactors.
Safety Engineering.
This field of engineering has as its object the prevention of accidents. Safety engineers develop methods and procedures to safeguard workers of hazardous occupations.The y also assist in designing machinery, factories, ships, and roads, suggesting alterations and improvements to reduce accidents.
