Development of an efficient, physics-based model that simulates dominant source noise mechanisms associated with the interactional aerodynamics between the airframe and a pusher-propeller system. This local phenomenon generates a non-uniform flow field [3] velocity deficit downstream that is subsequently ingested by the propeller.

As the propeller rotates behind these surfaces, each blade encounters this non-uniform flow field as a time-varying inflow disturbance that causes unsteady propeller blade loads and impulsive noise radiation.

The unsteady nature of such blade loads is known to strongly influence the harmonic tones of external noise radiation and subsequently the aural detection distance [4]. The tool should be reduced order [5] in nature but capture the physics of the shear-layer and the non-uniform flow field under realistic pressure gradients, turbulence sources, and their corollary impacts on propeller sound generation.

The tool should be applicable to the range of vehicle designs in consideration by DoD and Army Joint Multi-Role JMR [6] and must be able to run efficiently on a standard personal computer.

Proof-of-concept tool must be compared with at least one set of experimentally acquired inflow and blade loads data not used in the generation of the model.

Develop strategies to generate unsteady inflow predictions that are scalable to full-size systems. Develop technology transition plan and initial business case analysis. The objective of phase II is to further develop the reduced-order inflow prediction tool and implement output with a rotor noise prediction model.

Multiple inflow and blade load predictions must be fed into existing rotor noise prediction tools with resulting noise predictions compared to experimentally acquired rotor noise data for similar conditions.

Refine transition plan and business case analysis. Further development of the above propeller inflow prediction tool to become finalized. Final tool must be well validated against experimental data and will provide a predictive capability to assess performance and noise impacts from new pusher-propeller configurations and noise suppression technologies for future compound VTOL aircraft.

The integrated path from vehicle configuration and flight condition to predicted noise footprint must be well validated and documented. The resulting tool is applicable to both military and commercial aircraft and rotorcraft. The improved inflow modeling capabilities will provide the missing data needed to improve existing rotor noise models.

Develop an innovative room temperature installation method to achieve precision interference fits for bearing liners made of fiber reinforced metal matrix composites used in aerospace drive system assemblies. Bearing liners and inserts are used in a variety of aerospace structures to support the position of shafts as a sacrificial element that protects mating components from concentrated stresses, cyclic loads, and fret wear.

Rotorcraft gearbox housings are typically manufactured from magnesium or aluminum alloys, and use steel bearing liners. Bearing liners are typically installed using conventional interference press-fit or thermal shrink-fit installation processes. In shrink-fit applications, the achievable interference is dependent upon the thermal expansion of the bearing, which may severely constrain the materials suitable for the application.

There are also corrosion issues that arise from the condensation associated with use of cryogenic fluids when freezing or shrink-fitting a liner into place.A coupling is a mechanical device used to connect two rotating shafts for the purpose of transmitting torque from the driver to the driven piece of rotating equipment.

There are two basic classes of industrial couplings: rigid and flexible. Feasibility of Improvised Thermo Coupling for Local Electrical Consumption Essay.
