The Engineering Department

ATI has a permanent engineering department with full-time, in-house capabilities.  All technical work is performed in house.  In addition to providing the client better and more rapid service, this provides the client a higher degree of confidentiality and security, since sensitive information does not leave our company.

Capabilities

We have career backgrounds in mechanical design, structural analysis, fluid and aerodynamics, electronics and computer science disciplines.  Daily basis application work areas are air transport/airdrop systems design and development, including ground handling equipment, in-aircraft air transport equipment, cradles, restraint systems, airdrop rigging systems design, airdrop extraction dynamics analysis, airdrop trajectory analysis, landing impact shock mitigation dynamics analysis, design of helicopter external transport sling systems and the structural analysis of mechanical designs.  ATI is familiar with and uses many Military Standards (Mil-Specs) as well as the SAE, AMS and ASTM standards on a daily basis.

32-foot Type V platform manufactured by ATI, together with load design and developed by ATI, August 1999.

 We are familiar with and have  generated structural substantiation reports to Federal Aviation Regulations Parts 23, 25 and 27 standards when stress analyzing and documenting extensive airframe modifications to heavy transport and light aircraft.

28-foot RIB (Rigid-hull Inflatable Boat) airdrop load for dropping into water.  Manufactured by ATI, together with load design and developed by ATI in 1996.  The largest RIB airdrop load in the world.

Engineering approaches make use of in-house 3-D CAD/CAM programs, solids modeling and linear and non-linear structural Finite Element Analysis.  We can exchange engineering graphics data in IGES, SAT (ACIS), DXF, DWG and numerous other popular formats.

ATI often writes its own custom dynamics analysis programs for equipment-to-aircraft loading and unloading kinematics, airdrop cargo extraction dynamics, parachute trajectory analysis, cargo water entry dynamics and land cargo shock mitigation dynamics.  ATI writes computer programs in various brands and dialects of FORTRAN, BASIC, C, C++ and assembly.
