T-72/T-90 Auto-Transmission Feasibility -- 2

I need a concise but technically rigorous study that determines whether an automatic or hydro-mechanical transmission can be successfully retrofitted into legacy T-72 and T-90 main battle tanks.

The heart of the work is a power- and driveline-centred analysis: I want clear answers on whether available automatic gearboxes can meet the torque demands of these platforms and fit inside the current drivetrain envelope. To get there you will:

• Reverse-engineer the existing gearbox space, linkages and cooling paths from the hull and produce an accurate CAD envelope.
• Compare global MBT automatic transmissions, highlighting torque curves, gear ratios, power density and any built-in hydraulic retarder data.
• Examine torque-converter options in depth, showing how each would couple to the V-46/V-92S2 engines and what adapter housings might look like.
• Flag any hull or crew-station changes needed to accommodate shifters, electronic control units and upgraded cooling circuits.

Deliverables
1. Native 3-D CAD model (.step or Parasolid) of the current gearbox bay plus proposed automatic transmission package.
2. Engineering report (≈25 pages) walking through calculations, interference checks and retrofit pathway.
3. Executive slide pack (10–12 slides) summarising feasibility findings for senior decision-makers.

I’ll shortlist freelancers who can show past work on heavy-vehicle powertrain integration, especially those comfortable with drivetrain FEA, CFD for oil cooling, and MIL-STD documentation. Share one or two relevant projects and note which CAD/CAE tools you’ll use—CATIA, Creo, NX, Abaqus, Ansys, etc.

I’m aiming for an initial concept review in six weeks, so outline your milestones and how you’ll keep the communication flow clear during that period.
