Development of a stand for measuring thrust of micro-jet thrusters based on machine vision [PDF]
In the presented work, the issues of measuring the thrust force of spacecraft thrusters are considered. A program for determining the thrust force based on machine vision has been developed.

Aerodynamics of thrust vectoring [PDF]
Thrust vectoring as a means to enhance maneuverability and aerodynamic performane of a tactical aircraft is discussed. This concept usually involves the installation of a multifunction nozzle.

Device measures reaction engine thrust vector deviations [PDF]
Gimbal mounted test device measures thrust vector deviation of reaction engines in terms of angular displacement and thus precludes force ...

This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Large-scale static investigation of circulation-control-wing concepts applied to upper surface-blowing aircraft [PDF]
The use of a circulation control to deflect turbofan engine thrust beyond 90 deg. has been proven in full-scale static ground tests of the circulation-control-wing/upper-surface-blowing (CCW/USB) concept. This powered high-lift system employs a circular,

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]
We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition

Bloodstream infections (BSI) are one of the leading causes of mortality and morbidity in both civilian and military populations. This paper summarizes recent progress in novel treatment strategies to manage BSI arising from both bacterial and fungal pathogens using molecules, particles, and materials to elicit host‐directed immunity.

Experimental performance of a ventral nozzle with pitch and yaw vectoring capability for SSTOVL aircraft [PDF]
Aircraft with supersonic, short takeoff, and vertical landing capability were proposed to replace some of the current high-performance aircraft. Several of these configurations use a ventral nozzle in the lower fuselage, aft of the center of gravity, for

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...
