AERO ENGINE & COMPONENT TEST FACILITIESMobile Engine Test System (METS) For Lockheed Martin C130H/J and P3 Orion Aircraft • As part of the total integrated logistics support for the Lockheed Martin C130 and P3 Orion aircraft, Aerotest Limited have designed, developed and supplied advanced open air Mobile Engine Test Systems (METS) which are capable of performance testing the following: • Hercules C-130H Allison T56-A15 power plant installed into a Quick Engine Change Unit with a Hamilton Standard 54H60-91 propeller installed. • Allison T56/ 501 bare power plant with a Hamilton Standard 54H60-91 propeller installed. • Hercules C-130J AE2100D3 power plant installed into a Quick Engine Change Unit with a Dowty Aerospace R391 six bladed composite propeller installed. • Adaptability to support the Lockheed Martin P3 Orion Allison T56-A14 power plant installed into a Quick Engine Change Unit with a Hamilton Standard 54H60-77 propeller installed. A METS Facility provides the following advantages: • A flexible testing solution within a safe and efficient environment. • Proves the quality of the overhauled power plant, propeller and nacelle as individually or a complete assembly - fully tested and ready for a ONE TIME aircraft installation. • A Dynamometer Test Cell for bare engine testing is no longer required. • “State of the Art” Data Acquisition hardware platform which communicates back to the control cabin via a single Ethernet connection/cable. • The DAQ hardware is incorporated into a temperature controlled ‘Field Instrumentation Enclosure’ which typically houses other ancillary sensors & equipment e.g. pressure sensors, pump contactors, starters etc. • Prevents the aircraft being used as an expensive test facility, thus increases aircraft availability. • One facility catering for multiple aircraft platform. A METS Facility comprises of: Test Trailer & Mounting Frame including the following: • Test trailer with turntable steering, adjustable tow-arm equipped with NATO standard towing eye, brake system and foam filled tyres. • QECU’s and power plants are installed onto an aircraft standard Duplex stainless steel mounting frame at the same propeller centreline height as that of the aircraft wing. This reduces the amount of propeller ground-tip vortices and FOD hazards, which can damage the propeller and power plant. • Test trailer retention & safety system thrust tie-down chains which include integral spindle tensioners connecting to ground anchor plates complete with chemical anchors rated for C130J maximum thrust loads, QECU mounting frame seizure reaction tie-down wire assemblies with integral spindle tensioners connecting to ground anchor plates complete with chemical anchors and an integral fifteen ton stabilizing jacks and integral run-away trip wire. • The Aerotest METS test trailer is the only unique facility in the world to be equipped with optional front and rear hydraulic access scissor lift platforms reducing aerodynamic backwash blockage and resultant induced strain on the insta

AERO ENGINE & COMPONENT TEST FACILITIES A METS Facility comprises of: Test trailer & Mounting Frame including the following: • As well as ‘optional‘ front and rear hydraulic scissor platforms, the Aerotest METS can also include fixed personal work platforms – front and rear. • The Aerotest METS can also facilitate the installation of nominated ‘bare’ engines (T56-A14/A15 & 501-D22A), using a series of demountable support frames. These frames are designed to support the engine at the propeller gearbox end. • Personal access step located either side of the trailer to gain access to either...

AERO ENGINE & COMPONENT TEST FACILITIES Acoustic control cabin A METS Facility comprises of: • Hand held radio charging station. Acoustic control cabin including the following: • Terminations cabinet with circuit breaker protection. The 45 Db rated “state of the art” Acoustic Control Cabin is a high quality unit, based on the external dimensions of an ISO 20ft shipping container, to make transportation and handling easier. • Mains Power Single 240 volt 50/ 60 Hz electrical distribution board. The METS operators will benefit from the cabins enhanced acoustics, consol ergonomics and...

AERO ENGINE & COMPONENT TEST FACILITIES The Aerotest METS Facility also offers additional features: Optional QECU Air Start System • The Aerotest METS air start system replaces the high maintenance cost of aircraft / GSE Auxiliary Power System (APU) to provide compressed air to the test trailer and engine interface connection flange. • The Aerotest METS Supervisory Control and Data Acquisition (SCADA) system has been developed using National Instruments globally supported ‘LabView’ software to run within the well proven and reliable MS Windows-7 operating environment. • The system comprises...
