Abstract: A wheel anti-theft apparatus includes a base plate and an outer plate. The base plate includes a locking pin and stud holes, and the outer plate includes lug nut security sleeves and a locking pin receiver. Studs located on a vehicle plate on a vehicle are inserted through the stud holes of the base plate. A wheel is then placed on the base plate with the studs extending through the stud holes of the wheel. The locking pin extends through the center of the wheel. Lug nuts are screwed onto the studs to secure the wheel onto the vehicle plate and the base plate. The outer plate is placed on the wheel. The lug nut security sleeves fit over the lugs nuts and the locking pin is disposed in the locking pin receiver.

Abstract: A system for directing airflow, a gas turbine engine, and a method for directing airflow exiting a cascade of internal airfoils are provided. An exemplary method for directing airflow exiting a cascade of internal airfoils includes coupling a first plasma generating device on a first surface and a rounded trailing edge of each of the internal airfoils. The method also includes coupling a second plasma generating device on an opposite second surface and the rounded trailing edge of each of the internal airfoils. Further, the method includes selectively energizing the first plasma generating device and the second plasma generating device on each of the internal airfoils to produce a plasma and to selectively alter a direction of local airflow around each of the internal airfoils to produce a combined airflow exiting the cascade in a desired direction.

Abstract: A diffuser is provided that includes a first wall, a second wall, and a first plasma actuator. The first wall has a radially-extending section and a curved section. The second wall has a radially-extending section and a curved section that are spaced apart from the radially-extending section and the curved section of the first wall such that the curved section of the second wall is disposed radially inwardly from the curved section of the first wall and a flow path is defined therebetween. The first plasma actuator is disposed on the curved section of the second wall, and the first plasma actuator is adapted to generate a first electric field to ionize a first portion of air flowing along the flow path to form a plurality of ionized species capable of inducing a second portion of air to flow in a desired direction.
