The present concepts include a zero-porosity structure having a plurality of structural elements arranged to provide a negative Poisson's ratio and, further, a new mechanism to generate negative Poisson's ratio is single material, zero-porosity structure.

Zero-porosity NPR structure and tuning of NPR structure for particular localities

In at least some aspects, an auxetic structure includes a first sheet defining therein a plurality of a plurality of structural elements projecting from the first sheet, the plurality of structural elements being arranged to provide a negative Poisson's ratio, and a second sheet disposed adjacent the first sheet to define a first internal cavity between the first sheet and the second sheet. In yet other aspects, one or more additional sheets may be advantageously provided to provide a multi-layered structure having auxetic properties.

Negative poisson's ratio waffle structures

A system includes a turbine engine having a fuel injector. The fuel injector includes fluid ducts, each having a fuel inlet coupled to a distinct fuel source. The system includes a compressed air source that provides compressed air simultaneously to the fluid ducts, and a convergence point where combined fuel and air streams from the ducts are mixed. The fuel inlets are in a parallel flow arrangement such that no fuel from one fuel injector is present at another fuel injector.

Method and apparatus for isolating inactive fuel passages

A material which exhibits auxetic characteristics and control of thermal expansion characteristics while experiencing significant stress reduction is disclosed. The material has a repeating pattern of void structures along both lateral symmetry lines and longitudinal symmetry lines.

Auxetic structure with stress-relief features

One aspect relates to an apparatus having a combustion chamber and a duct in fluid flow communication with the combustion chamber. The apparatus includes at least one opening adapted for delivering a liquid fuel into the duct. The apparatus further includes at least one passage adapted for delivery of a gas upstream of the at least one opening for minimizing the entrance of a fluid other than the gas into the fuel delivery opening.
