(Linear Innovative Thrust Reversal Actuation System)
Task:
The thrust reverser flaps of a commercial aircraft are to be electrically driven contrary to the previous hydraulic drive method.
Solution:
Highly utilized double-sided, transverse force-free linear motor in short stator design.
Result:
Active volume 4,5 l (0,0045 m³)
Possible power for short-term 12000 N
The drive task requires 7000 N for a short time at a limited current.
The force density corresponds to approx. 50 – 60 % of a hydraulic cylinder, with equal forces in both directions.
Advantage:
Oil free (environment, risk of fire)
High control dynamics
Design freedom for other geometries
High efficiency
