Abstract: The present disclosure's side-arm recovery system enables large Unmanned Aircraft Systems (UASs) to operate from small vessels or from ground sites with a minimal footprint. The side-arm recovery system allows arresting an UAS independent of a runway. On the ground or on a ship, the system makes use of a specialized crane system that includes capture and energy absorption devices. A fuselage-mounted top-hook snags a horizontal cable and the arresting forces act in the plane of symmetry through the central structure of the UAS. After the capture energy is absorbed, the recovery system safely lowers the aircraft to a ground handling cart. The same system can be combined into a launcher and retriever system which further reduces the footprint by eliminating the need for a separate launcher.

Abstract: An abradable coating for a gas turbine engine includes a bond coat, an intermediate layer, and a porous layer. The bond coat includes a metal coating and a thickness from 0.152 millimeters to 0.229 millimeters. The intermediate layer includes a ceramic material and a thickness from 0.051 millimeters to 0.381 millimeters. The porous layer includes a porous ceramic material. The porous layer also includes a porosity greater than thirty-five percent of a volume of the porous layer. The porous layer further includes a thickness from 0.127 millimeters to 1.524 millimeters.

Abstract: A saw blade comprises a plate having a plurality of teeth. Each of the teeth includes a tip where the tip has a smooth curved surface welded to the plate. The tip comprises a solid piece of hard material and has a generally rounded wedge shape. A method of forming a saw blade having cutting tips welded to the plate is also provided.

Abstract: A support stand (2) for a sanding apparatus having a housing, a motor, and a sanding belt of abrasive material adapted to be driven around a plurality of rollers by means of the motor is disclosed. The support stand (2) comprises a body portion (6) having recesses (10, 14, 18, 22) for engaging corresponding parts of the sanding apparatus to expose the sanding belt of the sanding apparatus, and a control knob (26) mounted to the body portion (6) to be accessible by a user's hand when the sanding apparatus is supported on the support stand (2). The support stand also has a wheel (36) having a friction belt (38) for engaging a belt speed adjustment knob of the sanding apparatus to enable adjustment of the speed of the sanding belt of the sanding apparatus in response to rotation of the control knob (26) in order to control the rate of removal of material by the sander.
