Abstract: A mid-turbine frame located in a gas turbine engine axially aft of a high-pressure turbine and fore of a low-pressure turbine includes an outer frame case, an inner frame case, and at least a first spoke connecting the outer frame case to the inner frame case. The first spoke is tightened so as to be in tension during substantially all operating conditions of the gas turbine engine.

Abstract: A gas turbine engine has the convergent flaps and seals of an adjustable cross-sectional area nozzle connected to associated liners with a thermally compliant bracket. The bracket includes spaced feet with an intermediate notch spaced away from the liner. In this manner, a temperature gradient along the liner can be easily compensated at the connection of the bracket to the liner by adjustment within the notch. In other features, the bracket is riveted to the liner, providing further resistance to thermal expansion due to temperature gradiations.

Abstract: A convergent/divergent nozzle for a gas turbine engine includes liners that are attached to the convergent flaps and seals. The liner is formed of two separate plates. By splitting the liner into two separate plates, a thermal break is provided between the two. Thermal stresses on a downstream plate are not as readily transferred to an upstream plate. External stresses on the upstream plate are not transferred as readily to the downstream plate. The two liner plate portions, and a separate backing plate all have faces that abut and are riveted together. These faces provide a flow blocker to maintain a lower pressure downstream of the flow blocker.

Abstract: A modular portable gaming simulator system includes a transport trailer with at least one movable sidewall to which two or more gaming simulation stations are attached. The movable sidewall can be selectively raised and lowered between a transport or upright position for transporting the system, and a deployed or active position for displaying and operating the gaming simulation stations. The gaming simulation stations are interconnected so that the gaming simulation stations can interactively execute a software program application, such as in head-to-head competition. In the deployed position, the movable sidewall forms a stage on which the gaming simulation stations rest. In order to transport the system, the sidewall is raised into the upright or transportable position for transportation. During transportation, the gaming simulation stations remain attached to the sidewall in a horizontal, sideways position.
