BTR 185 – double counter-rotating retractable thruster
The presence of a composite, aluminium or steel counter flange, separated from the system’s supporting structure, makes the installation of the entire system easy, safe and compliant to current regulations on joints requirements.
The engine joined to the structure inside the keel, and a single moving body crossing the in-out barrier as well as a protection against mechanical overloading caused by accidental impacts when the system is open, make the Quick projet especially safe.
A further guarantee of reliability is the high quality materials (Nibrall and AISI316) used for both designed and commercial parts.
High galvanic protection by means of sacrificial anodes.
Reduced sizes and integrated electronicscomplete the list of BTR Quick propeller advantages.
