Advanced air mobility (AAM) are systems that incorporate support for next-generation transport such as such as remotely piloted, autonomous, or vertical take-off and landing (VTOL) aircraft. [1] [2] [3] This includes those powered by electric or hybrid-electric propulsion. [4] AAM seeks to support unmanned aerial systems (UAS) and sustainable ...
Urban air mobility is a subset of a broader advanced air mobility (AAM) concept that includes other use cases than intracity passenger transport; [1] NASA describes advanced air mobility as including small drones, electric aircraft, and automated air traffic management among other technologies to perform a wide variety of missions including ...
The National Advanced Air Mobility Center of Excellence is a research facility dedicated to studying air mobility and Unmanned Aircraft Systems (UAS). It contains 30,000 square feet of administrative, laboratory, meeting, and collaboration space with an additional 25,000 square feet of aircraft hangar space.
A-motility (adventurous motility) [5] [13] [16] as a proposed type of gliding motility, involving transient adhesion complexes fixed to the substrate while the organism moves forward. [13] For example, in Myxococcus xanthus, [5] [6] [13] [17] a social bacterium. Ejection or secretion of a polysaccharide slime from nozzles at either end of the ...
Functional mobility, often referred to as "transferring." This includes the ability to walk, get in and out of bed, and get into and out of a chair. The broader definition covers moving from one place to another while performing activities and is useful for people with varying physical abilities who can still move around independently.
Motility differs from mobility, the ability of an object to be moved. The term vagility means a lifeform that can be moved but only passively; sessile organisms including plants and fungi often have vagile parts such as fruits, seeds, or spores which may be dispersed by other agents such as wind, water, or other organisms.
The definition of life has long been a challenge for scientists and philosophers. [2] [3] [4] This is partially because life is a process, not a substance. [5] [6] [7] This is complicated by a lack of knowledge of the characteristics of living entities, if any, that may have developed outside Earth.
Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. [1] It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics.
