Prime power and EV charging are two areas that can benefit from the Karno linear generator beginning later this year.

This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical and head tracker performance of airborne Head Worn Displays (HWDs). This document covers methods for conformal HWD systems that are intended for use in the flight deck by the pilot or copilot. The focus of this document is for displays that generate HWD equivalent information. These measurement methods are provided for testing to the requirements of AS7377.

This specification covers an aluminum alloy in the form of die forgings, hand forgings, and rolled rings 4 inches (102 mm) and under in nominal thickness, and forging stock of any size (see 8.6).

Abstract In the process of injection molding, the vacuum pump rear housing is prone to warping deformation and volume shrinkage, which affects its sealing performance. The main reason is the improper control of the injection process and the large flat structure of the vacuum pump rear housing, which does not meet its production and assembly requirements (the warpage deformation should be controlled within 1.1 mm and the volume shrinkage within 10%). To address this issue, this study initially utilized orthogonal experiments to obtain training samples and conducted a preliminary analysis using gray relational analysis. Subsequently, a predictive model was established based on a one-dimensional convolutional neural network (1D CNN).

Abstract With the use of the stepped surface of the friction pairs of the stepped bearings (SB) in the high-speed centrifugal pumps, its liquid film thickness is suddenly changed and it was discontinuously distributed in the direction of motion of pump. To ensure the continuity of the liquid film thickness and enhance the lubrication efficiency of the pump, based on the lubrication model of the SB, two other structures of the inclined surfaces [inclined bearings (IB)] and curved surfaces [curved bearings (CB)] used to replace stepped surfaces of the SB are investigated, respectively. Under the same conditions of the minimum thickness of the liquid film and initial dimensions of the sliding friction pairs, the influence of both the thickness ratio (α) of the liquid film and dimension ratio (β) in the direction of motion of SB, IB, and CB on the bearing capacity and friction coefficient of the liquid film are simulated and analyzed, respectively.

This specification covers an aluminum alloy in the form of seamless round tubing with wall thickness from 0.025 to 0.500 inch (0.64 to 12.70 mm), inclusive (see 8.6).
