THRUST STANDS – OH & IM

Overhead Thrust Stands

Overhead thrust stand A tec designs, assembles, and installs overhead thrust frames to hold a variety of high thrust and high bypass engines, including the JT8, CF34, CFM56, JT9, CF6, RB211, PW4000, V2500, and PW2000 engines. Powerful jet engines require thrust stands that can withstand the high loads and air flows interfacing with the engine test frame. Atec has designed and installed many such aeroengine test cells with overhead thrust frames to test these high capacity engines for our clients worldwide. Celtech Corp. and Vital Link, Inc. add significantly to our military thrust stand design and fabrication expertise.

Computer modeling of all structural and fluid (air flow) considerations are standard for our designs, with most having been proven in previous use. Ample factors of safety and engine growth issues are also considered in our test cell thrust frame and adapter designs. Operating factors such as utilities interfaces, easy engine adapter connection, vibration damping/isolation, hoists integration, monorail utilization, exhaust positioning, work heights determination, sub system mesh/clearances, maintenance/inspection access and worker safety are considered in our respected jet engine thrust stand designs.

 

Atec Overhead Thrust Frame Key Features

  • Load ratings in excess of 100,000 lbf
  • Engine is suspended and tested in test cell for increased engine test volume
  • Available on separate steel superstructure (Arachnid™) to reduce building cost and vibration
  • Can be integrated into building structure to maximize airflow and workspace utilization
  • Provide monorail access for easy engine installation and removal
  • Engine specific adapters allows rapid engine change
  • Accurate and precise thrust measurement
  • Overhead thrust frame designed for optimal air flow
  • Can be installed in existing buildings or new test cells
  • Designed to a minimum safety factor of 3 times to yield and 5 times to yield
  • Commonly load tested to 2X rated load
  • Ability to relocate reclaimed equipment (if needed)

Intermediate Thrust Stands

06d0252-006 T he Atec AHT50000-1 Advanced Mobile Engine Thrust Stand (AMETS50) provides for performance testing of all current USAF jet engines with thrust up to 50,000 lbs. It is USAF approved replacement for the current A/M37T-20 thrust trailer system with several safety and performance improvements.  Original A/M37T-20 test stands are available through Celtech Corp.

Originally designed using Test-Standsmodern FEA techniques to replace the thrust stand in A/F32T-8 facilities, the Advanced Mobile Engine Thrust Stand is now fully compatible with all existing T-10, T-8, T-4 hush houses and engine adapter kits/equipment, including all F-100/F-110, F-119 and F-135 engine types.  It maintains all standard M37 (48″ and 60″) rail interface dimensions and hole placements, making it forward and backward compatible with all legacy test equipment. Now available in Left or Right (mirror) configurations to align work area access for stand and test cell. It is now being delivered into USAF and allied inventories. T20C testing is now proven for the Navy and other users for F404 and F414 engines, as a low cost alternative to the JETI/SETI/TPTI control systems.
