Whirl Towers
Whirl Towers are used in rotorcraft blade balancing, blade development, main rotor hub system development and performance analysis such as blade lift/thrust or blade hover envelope during varying or constant blade speeds. The Whirl Tower can be simple or complex system, small or large depending on the customer requirements. Blade systems can be developed for large manned and smaller unmanned (Drone) system.
Small systems can operate blades at thousands of rpms while large systems typically operate under 250rpm. Current and future research and development on blades and propellers keep researches constantly evaluating materials, active blade structural and to reduce ice formation, sound, balance and vibration. Through the use of these Whirl Towers increase blade and main rotor hub systems efficiencies are determined smaller diameter, high power and higher speeds blade systems are being developed and require validation and testing. Counter rotating Co-Axial rotor testing system can be supplied for testing blades and full head development.
Whirl Tower Systems can vary in size from small single digit Hp (kW) to large thousands of Hp (kW). MAE can supply your next Whirl Tower System.

Helicopter, Tiltrotor and Rotorcraft aircrafts require testing of their individual powertrain components as well as the completely assembled powertrain system. MAE specialized in testing these individual components and fully assembled powertrain systems. Testing can be a simple spin-up loaded test or complex inflight simulation testing using 6-dof hydraulic blading loading simulators attached to Mast/Tail rotor/Tiltrotor blade shafts. MAE is capable of meeting your testing requirements and needs.
MAE supplies a larger variation of test stands for the aviation industry, some test stands are airframe specific, other test systems work across a various airframe sizes and configurations, while other test stands are product specific or operate across various product sizes. MAE will meet your testing needs for Production, R&D and Remanufacturing Validation Test Stands.
