Aerospace engineers may design specific aerospace products, such as commercial and military airplanes and helicopters; remotely piloted aircraft and rotorcraft; spacecraft, including launch vehicles and satellites; and military missiles and rockets.

SYE 4802 - Helicopter Theory3 Class Hours 0 Laboratory Hours 3 Credit Hours Prerequisite: SYE 3801 and Engineering Standing The course is designed for students interested in helicopter theory as an application of large scale complex system. It presents a comprehensive introduction to rotorcraft technology. It covers a range of disciplines from design, aerodynamics and propulsion points of view. It teaches what a helicopter engineer or enthusiast needs to know how to analyze an existing design or participate in the development of a new one. The course covers all aspects of hover, vertical flight and forward flight.

In engineering, damage tolerance is a property of a structure relating to its ability to sustain defects safely until repair can be effected. The approach to engineering design to account for damage tolerance is based on the assumption that flaws can exist in any structure and such flaws propagate with usage. This approach is commonly used in aerospace engineering, mechanical engineering, and civil engineering to manage the extension of cracks in structure through the application of the principles of fracture mechanics. A structure is considered to be damage tolerant if a maintenance program has been implemented that will result in the detection and repair of accidental damage, corrosion and fatigue cracking before such damage reduces the residual strength of the structure below an acceptable limit.

Not all structure must demonstrate detectable crack propagation to ensure safety of operation. Some structures operate under the safe-life design principle, where an extremely low level of risk is accepted through a combination of testing and analysis that the part will never form a detectable crack due to fatigue during the service life of the part. This is achieved through a significant reduction of stresses below the typical fatigue capability of the part. Safe-life structures are employed when the cost or infeasibility of inspections outweighs the weight penalty and development costs associated with safe-life structures.[1] An example of a safe-life component is the helicopter rotor blade. Due to the extremely large numbers of cycles endured by the rotating component, an undetectable crack may grow to a critical length in a single flight and before the aircraft lands, result in a catastrophic failure that regular maintenance could not have prevented.

You can find employment with the military such as the US army, helicopter design and manufacturing companies, air medical industry, government business organizations, international development agencies and more. Some examples are AECOM, Columbia Helicopters, PAE, Unical MRO, Air Methods, Lockheed Martin, UTC Aerospace Systems and Life Flight Network.

Aerospace engineering deals with designing and building machines that fly. It is one of the newest branches of engineering, and began in the 19th century with the first experiments in powered flight. As technology progressed, two specialties emerged; aeronautical engineering, which involves designing aircraft such as powered lighter-than-air craft, gliders, fixed-wing airplanes and jets, autogyros, and helicopters; and astronautical engineering, which focuses on the design and development of spacecraft.

Helicopter and autogyro designs progressed incrementally over the next few decades. Juan de la Cierva is credited with inventing the autogyro, a type of aircraft with fixed wings that uses a rotor for lift and a propeller for thrust. His advancements in rotary design led directly to the first modern helicopter, which is generally attributed to Igor Sikorsky in 1942.

Aerospace engineering requires in-depth skills and understanding in physics, mathematics, aerodynamics and materials science. These professionals must be familiar with advanced materials such as metal alloys, ceramics, polymers and composites, the BLS said. This knowledge allows engineers to predict the performance and failure conditions of designs before they are even built.

Our 200 Series Helicopter Maintenance Platforms are specially designed maintenance stands that provide access to all major maintenance areas of rotor craft for routine inspection, maintenance, and repair of helicopter components.

Professor Ron Adrezin, Ph.D., P.E. is a Professor of Mechanical Engineering at the U.S. Coast Guard Academy in New London, Connecticut. He earned his B.E. and M.E. at The Cooper Union, and his Ph.D. at Rutgers University. All are in mechanical engineering. He has been a licensed professional engineer for over twenty-five years and worked primarily in the aerospace and biomedical engineering fields. He has utilized the capabilities of additive manufacturing for almost two decades, originally applying it to space suit and helicopter centered projects. At the Academy, he teaches analysis and design courses. Professor Adrezin participated in Arctic West Summer 2015 on USCGC Healy, a medium-duty icebreaker. He led a successful trial to use additive manufacturing to replace critical components at sea, with details published in the Naval Engineers Journal. During the summer of 2018, he deployed on USCGC Forward to conduct his corrosion research. This included advanced coatings and the corrosion of buoys. His most recent patents are based on his work utilizing shape memory alloys and additive manufacturing in the development of small mechanisms. He is coordinating efforts to evaluate modern anti-corrosive coatings, and studying the effects of a salt-water environment on stainless steel and nylon components produced through additive manufacturing. This is a collaborative effort with researchers at Sandia National Laboratories. 59ce067264
