Turbine Rotor Assembly Systems

RPI UK (Bath, UK) has installed the first of two integrated rotor measurement and assembly platforms (iMAPs) at a major aero engine maintenance, repair and overhaul (MRO) facility. RPI’s iMAP technology is used by the MRO facility after the engines are dismantled, to inspect each individual section of the engine for cracks, wear and distortion. Measurements are taken by AccuScan to check that component geometry meets original and regional board specifications. Once the components have been approved, repaired or replaced, the iMAP is used for engine assembly to ensure alignment and concentricity.

iMAP’s data acquisition software, AccuScan, enables measurement of up to 4,000 data points on up to eight surfaces simultaneously per revolution, thereby reducing process times to just two minutes. This inspection data is then used by the Rotor Stacking software to solve the mathematical problem of how to best assemble a multi-stage rotor to achieve minimum runout or unbalance of the finished rotor.

Heavy Fuel (HF) Engine

The new HF engine from Sky Power (Bad Homburg, Germany) runs on a kerosene-oil mix of 50:1 using JET A, JET A1 or JP-8. As part of the development of the engine, Sky Power has taken a new approach to HF technology. The goal was to heat up the fuel mixture in a reliable and controlled manner to achieve better starting properties. The new HF concept can also be applied as an upgrade to all injection engines of the SP-210 series. When configuring a propulsion system, customers have a choice of generators, starter-generators, power-supplies and complete hybrid configurations, and can now choose between different fuel types, to meet the application’s needs.

The newly developed KHU 100 manages the start-process jointly with the engine management unit ECU030. Both systems communicate through the CAN-Bus Interface. The temperature is controlled by sensors, installed in the drive unit. Engines with the twin-spark (TS) system also run at a lower idle. Safety and reliability increase in both single- and multiple-cylinder engines, and multiple-cylinder systems benefit from active redundancy of two independent ignition systems.

Integrated Air Bearings

In today’s manufacturing environment, moving machinery to optimize floor space, flex for lean manufacturing, or position for optimum productivity is imperative. Embedding air bearings on OEM machinery provides manufacturers with the ultimate capability to adapt and flex to ever-changing manufacturing configurations. Embedded air bearings can now be designed into the OEM equipment via an online toolkit available from AeroGo (Seattle, WA).

Air bearing systems utilize compressed air to lift and float heavy machines, structures and tooling within their own footprint. Air bearing technology works similar to a puck on an air hockey table, in that it eliminates friction – making heavy loads easy to move – and it floats on the surface without damaging the floor. This material handling method is inherently safe to operators due to very low lift height and reduced friction/low chance of strain. The embedded air bearing system is permanently integrated into the tool, machine, or structure. Wheeled casters, footers or bases are fitted with air bearing modules and a control console for adjustable air control.

Heat Pipes

Advanced Thermal Solutions, Inc. (ATS) (Norwood, MA) has expanded its line of flat and round copper heat pipes for electronics thermal management. ATS heat pipes transfer component heat with minimal temperature difference to dispense heat efficiently across heat spreaders. Liquid in the heat pipe turns to vapor by absorbing heat and removing thermal energy from hot component surfaces. The vapor travels to the cold end of the pipe, releases latent heat and condenses back to liquid. The liquid returns to the hot interface along an internal copper wick to provide continuous thermal management.

Every ATS heat pipe consists of a sealed copper tube, internal copper wick structure, and distilled water as its working fluid. Round profile heat pipes come in lengths from 200-300 mm and diameters from 4.0-8.0 mm. Flat profile heat pipes range in length from 100-250 mm, widths from 8.2-10.5 mm, and heights from 2.5-4.5 mm. Weights range from 8-33 grams. They are effective in temperatures ranging from 30-120°C. Other fluids and sizes can be accommodated with custom heat pipe designs by ATS.
