  • In-situ load system for calibrating and validating aerodynamic properties of scaled aircraft in ground-based aerospace testing applications
    Patent number: 9354134
    Abstract: An In-Situ Load System for calibrating and validating aerodynamic properties of scaled aircraft in ground-based aerospace testing applications includes an assembly having upper and lower components that are pivotably interconnected. A test weight can be connected to the lower component to apply a known force to a force balance. The orientation of the force balance can be varied, and the measured forces from the force balance can be compared to applied loads at various orientations to thereby develop calibration factors.

  • Method of calibrating a force balance
    Patent number: 9052250
    Abstract: A calibration system and method utilizes acceleration of a mass to generate a force on the mass. An expected value of the force is calculated based on the magnitude and acceleration of the mass. A fixture is utilized to mount the mass to a force balance, and the force balance is calibrated to provide a reading consistent with the expected force determined for a given acceleration. The acceleration can be varied to provide different expected forces, and the force balance can be calibrated for different applied forces. The acceleration may result from linear acceleration of the mass or rotational movement of the mass.

  • DAM SKIRT AERODYNAMIC FAIRING DEVICE
    Publication number: 20110204677
    Abstract: A method and device for the reduction of aerodynamic drag and for improved performance and stability of ground vehicles by reducing the mass and velocity of the flow passing under a vehicle is described. The device is particularly suited for a single unit truck system but may also be applied to a tractor-trailer truck system or any combination vehicle that includes a motorized lead vehicle pulling one or more non-motorized vehicles. The device is designed to control the flow from entering the undercarriage region from the front and side of the subject ground vehicle system.
