Mechanical Engineering is an engineering discipline that was developed from the application of principles from physics and materials science. Mechanical engineering involves the analysis, design, manufacturing, and maintenance of various systems. It is one of the oldest and broadest engineering disciplines.

The field requires a solid understanding of core concepts including mechanics, kinematics, thermodynamics, fluid mechanics, materials science, and energy. Mechanical engineers use the core principles as well as other knowledge in the field to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, motor vehicles, aircraft, watercraft, robotics, medical devices.

Aerospace engineering

Aerospace engineering is the branch of engineering behind the design, construction and science of aircraft and spacecraft. It is broken into two major and overlapping branches: aeronautical engineering and astronautically engineering. The former deals with craft that stay within Earth's atmosphere, and the latter deals with craft that operate outside of Earth's atmosphere.

While aeronautical engineering was the original term, the broader "aerospace" has superseded it in usage, as flight technology advanced to include craft operating in outer space. Aerospace engineering, particularly the astronautics branch, is often informally called rocket science.

automotive engineering

Modern automotive engineering is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles, buses and trucks and their respective engineering subsystems

Automotive engineers are involved in almost every.phpect of designing cars and trucks, from the initial concepts right through to manufacturing them.

Broadly speaking, automotive engineers are separated into three main streams: product engineering, development engineering and manufacturing engineering.

Product engineer (also called design engineer), that would design components/systems (i.e brake engineer and battery engineer). This engineer designs and tests a part, seeing that it meets all its requirements (i.e. the shock), performs as required, material meets desired durability and so on.

Development engineer, that engineers the attributes of the automobile. This engineer may provide to the design engineer what spring rate he/she requires to provide the "ride" characteristics required for the automobile to perform as desired, etc.

Manufacturing engineer, determines how to make it. In Toyota, for example, manufacturing engineering is regarded as a more prestigious career path than designing and developing the cars.

Product Engineering

Some of the engineering attributes/disciplines that are of importance to the automotive engineer:

Safety Engineering

Safety Engineering is the assessment of various crash scenarios and their impact on the vehicle occupants. These are tested against very stringent governmental regulations. Some of these requirements include: Seat belt and air bag functionality. Front and side crash worthiness. Resistance to rollover. Assessments are done with various methods and tools: Computer crash simulation, crash test dummies, partial system sled and full vehicle crashes.

Fuel Economy/Emissions

Fuel economy is the measured fuel efficiency of the vehicle in miles per gallon or litres per 100 kilometres. Emissions testing the measurement of the vehicles emissions: hydrocarbons, nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), and evaporative emissions.

Vehicle Dynamics

Vehicle dynamics is the vehicle's response of the following attributes: ride, handling, steering, braking, and traction. Design of the chassis systems of suspension, steering, braking, structure (frame), wheels and tires, and traction control are highly leveraged by the Vehicle Dynamics engineer to deliver the Vehicle Dynamics qualities desired.

NVH Engineering (Noise, Vibration, and Harshness)

NVH is the customer's impression both tactile (feel) and audible (hear) feedback from the vehicle. While sound can be interpreted as a rattle, squeal, or hoot, a tactile response can be seat vibration, or a buzz in the steering wheel. This feedback is generated by components either rubbing, vibrating or rotating. NVH response can be classified in various ways: powertrain NVH, road noise, wind noise, component noise, and squeak and rattle. Note, there are both good and bad NVH qualities. The NVH engineer works to either eliminate bad NVH, or change the �bad NVH� to good (i.e., exhaust tones).

Performance

Performance is the driver�s perception of the vehicle's power and pickup. This is influenced by vehicle acceleration, sound of the engine, accelerator pedal feel, and shift quality. Performance is perceived in various ways: wide-open-throttle (WOT) acceleration, 0-60 mph (0-100 km/h) -launch performance, or highway passing power.

Shift Quality

Shift Quality is the driver�s perception of the vehicle to an automatic transmission banana event. This is influenced by the powertrain (engine, transmission), and the vehicle (driveline, suspension, etc). Shift feel is both a tactile (feel) and audible (hear) response of the vehicle. Shift Quality is experienced as various events: Transmission shifts are felt as an upshift at acceleration (1-2), or a downshift maneuver in passing (4-2). Shift engagements of the vehicle are also evaluated, as in Park to Reverse, etc.

Durability / Corrosion Engineering

Durability and Corrosion engineering is the evaluation testing of a vehicle for its useful life. This includes mileage accumulation, severe driving conditions, and corrosive salt baths.

Package / Ergonomics Engineering

Package Engineering is a discipline that designs/analyzes the occupant accommodations (seat roominess), ingress/egress to the vehicle, and the driver�s field of vision (gauges and windows). The Package Engineer is also responsible for other areas of the vehicle like the engine compartment, and the component to component placement. Ergonomics is the discipline that assesses the occupant's access to the steering wheel, pedals, and other driver/passenger controls.

Climate Control

Climate Control is the customer�s impression of the cabin environment and level of comfort related to the temperature and humidity. From the windshield defrosting, to the heating and cooling capacity, all vehicle seating positions are evaluated to a certain level of comfort.

Drivability

Drivability is the vehicle�s response to general driving conditions. Cold starts and stalls, rpm dips, idle response, launch hesitations and stumbles, and performance levels.

Cost: The cost of a vehicle program is typically split into the effect on the variable cost of the vehicle, and the up-front tooling and fixed costs associated with developing the vehicle. There are also costs associated with warranty reductions, and marketing.

Program timing

To some extent programs are timed with respect to the market, and also to the production schedules of the assembly plants. Any new part in the design must support the development and manufacturing schedule of the model.

Assembly Feasibility

It is easy to design a module that is hard to assemble, either resulting in damaged units, or poor tolerances. The skilled product development engineer works with the assembly/manufacturing engineers so that the resulting design is easy and cheap to make and assemble, as well as delivering appropriate functionality and appearance.

Development Engineer

A Development Engineer is a job function within Automotive Engineering, in which the development engineer has the responsibility for coordinating delivery of the engineering attributes of a complete automobile (bus, car, truck, van, SUV, etc.) as dictated by the automobile manufacturer, governmental regulations, and the customer who buys the product.

Much like the Systems Engineer, the Development Engineer is concerned with the interactions of all systems in the complete automobile. While there are multiple components and systems in an automobile that have to function as designed, they must also work in harmony with the complete automobile. As an example, the brake system's main function is to provide braking functionality to the automobile. Along with this, it must also provide an acceptable level of: pedal feel (spongy, stiff), brake system �noise� (squeal, shudder, etc), and interaction with the ABS (anti-lock braking system)

Another.phpect of the development engineer's job is a trade-off process required to deliver all the automobile attributes at a certain acceptable level. An example of this is the trade-off between engine performance and fuel economy. While some customers are looking for maximum power from their engine, the automobile is still required to deliver an acceptable level of fuel economy. From the engine's perspective, these are opposing requirements. Engine performance is looking for maximum displacement (bigger, more power), while fuel economy is looking for a smaller displacement engine (ex: 1.4 L vs. 5.4 L). The engine size, though is not the only contributing factor to fuel economy and automobile performance. Other attributes include: automobile weight, aerodynamic drag, transmission gearing, emission control devices, and tires.

The Development Engineer is also responsible for organizing automobile level testing, validation, and certification. Components and systems are designed and tested individually by the Product Engineer. The final evaluation though, has to be conducted at the automobile level to evaluate system to system interactions. As an example, the audio system (radio) needs to be evaluated at the automobile level. Interaction with other electronic components can cause interference. Heat dissipation of the system and ergonomic placement of the controls need to be evaluated. Sound quality in all seating positions needs to be provided at acceptable levels.

Manufacturing Engineering

Manufacturing Engineers at automotive companies are involved in a wide array of manufacturing activities. They plan and engineer the assembly of whole vehicles as well as the individual parts that go into the vehicles. Design and layout of equipment and people, machine rates and line rates, specification of automation equipment, and manufacturing safety procedures are all some of the jobs that Manufacturing Engineers do.

Assembly plants build vehicles from parts they receive...they rarely build parts themselves. Manufacturing engineers at assembly plants plan out the body shop, engine and transmission placement, and the trim and chassis area of the final assembly. Seats, radios, interior trim panels, pick-up bedliners and wheels are examples of parts that need to be manufactured for a vehicle and whose creation would be overseen by an Automotive Manufacturing Engineer. While body panels, usually stamped sheet metal, have typically remained within the OEM, the general trend for all other parts is for them to be bought from outside suppliers. Most vehicles have greater than 60% supplier content (The Toyota Product Development System, Morgan and Liker)

The automotive industry has its own culture that Automotive Manufacturing Engineers need to know to effectively operate. The Automotive Industry Action Group (AIAG), a consortium composed of hundreds of participating companies, have established rules and procedures that ensure parts meet strict quality levels. An Automotive Manufacturing Engineer typically works with statistics and process controls, validating that the process that produces parts will always produce those parts with quality. They also search for ways to continuously improve the process between product upgrades.

Mechanical, Electrical and Plumbing (MEP)

Main articles: Mechanical engineering, Electrical engineering, and Building services engineering Mechanical and electrical engineers are specialists, commonly referred to as "MEP" (mechanical, electrical and plumbing) when engaged in the building design fields. Also known as "Building services engineering" in the United Kingdom, Canada and Australia. Mechanical engineers design and oversee the heating ventilation and air conditioning (HVAC), plumbing, and rain gutter systems. Plumbing designers often include design specifications for simple active fire protection systems, but for more complicated projects, fire protection engineers are often separately retained. Electrical engineers are responsible for the building's power distribution, telecommunication, fire alarm, signalization, lightning protection and control systems, as well as lighting systems.

An aviator is a person who flies aircraft for pleasure or as a profession. The first recorded use of the term was in 1887 as a variation of the French 'aviation', from the latin 'avis', coined 1863 by G. de la Landelle in "Aviation ou Navigation A�rienne".

The term aviatrix is sometimes used for a female aviator. The term is often applied to pilots, but is often extended to include air navigators, bombardiers, Weapon Systems Officers, and electronic warfare Officers. This should not be confused with the term naval aviator, which refers crew members in the United States Navy, Marines and Coast Guard.

There are also such minor aviation characters as wing-walkers who take part in aerobatic display sequences.

The term aviator (as opposed to "pilot" or other terms) was used more in the early days of aviation, before anyone had ever seen an airplane fly, and it had connotations of bravery and adventure. For example, the editors at the Dayton Herald, in an article of December 18, 1903 described the Wright Brothers' first airplane thus: "The weight, including the body of the aviator, is slightly over 700 pounds".

To ensure the safety of people in the air as well as on the ground, it soon became a requirement for an aircraft to be under the operational control of a properly trained, certified and current pilot at all times, who is responsible for the safe and legal completion of the flight. The first certificate was delivered by the Aero Club de France to Louis Bl�riot in 1908, followed by Glenn Curtiss, Leon Delagrange, and Robert Esnault-Pelterie. The absolute authority given to the Pilot in Command is derived from that of a ship�s captain.

Beverly Lynn Burns, first woman in the world to captain the Boeing 747 airliner In recognition of the aviators' qualifications and responsibilities, most militaries and many airlines around the world award aviator badges to their pilots as well as other air crews.
