Atec has handled many significant projects in terms of complexity and cost. As part of a project for the Navy, Atec demolished the existing internal system and a completely new test system was installed. Atec was instrumental in the design of a custom water-dynamometer, which allows the T64 and T700 engines to be tested inside the same test cell.

This included:
• Retrofit of T400 Engine Test Cell to accommodate T64 and T700 Series Turboshaft Engine Testing
• Design, manufacture, and install universal engine test stand
• Hydraulic dynamometers
• Closed-loop dynamometer cooling water system
• Improved airflow
• New ADAQ™, data acquisition and control system
• Upgraded operator control room, Fuel Delivery and measurement system, and new Air Start system for the T700 engine
• Install of new water cooling tower and piping, dual water dynamometer system (or the Versatile Engine Test System, VETS), electric start system for the T-64 engine
• Modification to the Air Intake system and new Exhaust system
• Upgraded Fire System
• Hazmat disposal of excavated soil and asbestos abatement in several areasTurnkey A250 TurboShaft Test Cell

Atec designed, fabricated, and Installed an A250 test cell for Air Logistics, a Bristow Company. This was a turnkey test system that enables rapid engine throughput, simple operator interface, and a data acquisition system that captures all required engine parameters. Atec took an innovative approach to applying load to the engine during testing by incorporating a regenerative electric drive that utilizes two high-speed electric motors. The electrical power genterated by the AC motors will not only provide mechanical braking torque for loading the engine, but also turn the load into useable electric power that is synchronized for use on the local power grid.

Project:
• Turnkey A250 TurboShaft Test Cell
• Configured with ADAQ™ data acquisition and control systemReciprocating Engine Test Cell to TurboShaft Engine Test Cell Conversion
Atec converted a marine test cell into a turbine engine test cell for a company in Sugar Land. The test cell is recognized for hot end and cold end drives, and is designed to test multiple engine types within the single cell.

Design for single cell testing of multiple engines (T56 derivatives)
Engine types: Rolls-Royce 501-KB, 501-KB5, 501-KB5S, 501-KC, 501-KC5, and 501-KF
 Capable of testing turboshaft engines up to 15,000 HP with additional adapters
 Floor-mounted skid with engine carts for quick engine change
 Air dynamometer interface with various engine shaft arrangements, Common with FEDS (T-24/T-33)
 Two exhaust stack systems to allow multiple engine test configurations with air dynamometer
 Oversaw installation of natural gas line
 Critical acoustic requirements
 Class 1, Div 1 test cell (explosion proof)
