The Saab Skeldar V200 is a unique and exciting entrant in the unmanned aerial vehicle (UAV) market, which is dominated by fixed wing aircraft. As a rotary wing aircraft, the Skeldar does not need runways to take-off or land from and can hover in one position. Skeldar is designed for land- and sea-based patrol, light …
In a wide range of industrial and defense applications, material are required to perform at extreme operating conditions involving large plastic deformation, high strain rates, elevated temperatures and severe dynamic pressure. Some examples of this application are perforating guns in the oil and gas industry, debris impact in aerospace engineering and ship collisions in naval engineering. …
It is well established that simulation provides substantial time and cost savings by accurately predicting performance of a proposed design, reducing the need for physical tests. However, a challenge for many design teams is that analyzing multiple non-linear components requires huge computational resources. A typical simulation takes about 30 hours to perform, which limits the …
Rubber is excellent at isolating shock and vibrations and reducing noise. Its damping properties make it particularly useful in engine mounts and suspension bushings. However, many factors affect the rubber’s damping characteristics and performance, for example, the heat generated during damping, repeated stretching which reduces stiffness, etc. Fillers in the rubber also influence its damping …
Cars require a number of automotive body seals – passenger doors, windows, engine and trunk lids, and sunroofs. While static seals, such as those around windshields, are important, they are relatively simple. Dynamic seals on the other hand, such as door and window seals, are complex in function, and therefore in design. They not only …
The human anatomy nervous system transmits signals to and from the brain for various voluntary and involuntary muscles. Nerve receptors also transmit data to the brain for heat, cold, pain and other sensations. The nerve fibers are protected by a covering or sheath. The ability to control, modify or block the signals from the receptors …
