RATMK - Ground-Drive

The RATMK family comprises hydraulic ground-drive motors and accessories used to perform Ram Air Turbine functional tests. Manufactured by Test-Fuchs, the family supports shop and ramp verification of RAT performance on approved Airbus programs. Aluminum lightweight construction aids safe handling, while standardized couplings ensure repeatable connections. Family kits include hose and storage provisions and stow in the PGRAT1 adapter drawer for organized deployment.

Keyfeatures

Hydraulic Ground-Drive – Uses shop hydraulic power to spin the RAT under controlled test conditions.

Aluminum Lightweight Build – Low mass supports safe manual handling and precise installation at the aircraft.

Standardized Couplings – Aeroquip AE 96997 M / AE 96996 P interfaces enable consistent, secure hookup.

Integrated Hose & Storage – Family provisions include hose sets and storage boxes for protected transport and staging.

PGRAT1-Compatible Stowage – Designed to fit the PGRAT1 adapter drawer for fast setup and tidy logistics.

Highlights

RATMK standardizes ground-drive solutions for Airbus RAT functional testing with organized stowage and common interfaces.

Application Cases

RAT Functional Testing – Ground-drive of Ram Air Turbines on approved Airbus programs.

Maintenance & Troubleshooting – Spin-up and verification during line and base maintenance.

Configuration Options

Safety & Operation

Hydraulic ground supply drives the RAT in a controlled manner for functional testing.

Clearly identified supply, return, and leakage connections simplify correct setup.

Standard Aeroquip couplings with protective caps maintain secure, repeatable interfaces.

Family kits support RAT functional test procedures for approved Airbus programs.

Organized storage reduces handling errors and contamination risk between tasks.

Mobility & Transport

Dedicated storage boxes secure motors and hoses during movement.

Compatibility with the PGRAT1 adapter drawer streamlines transport and staging.

Compact geometry eases positioning at the aircraft and in the workshop.

Durability & Corrosion Protection

Aluminum construction resists corrosion and reduces overall handling weight.

Protective caps help preserve coupling sealing surfaces between uses.

Robust housings and hardware support repeated shop and ramp operations.
