NOTAR
May I ask a complete bystander question please? I have always loved helicopters, both for their fascinating engineering and for way a flying machine can do such extraordinary things. However, as an engineer (non aero) I have always seen the Tail rotor as the weak link and viewed the NOTAR concept as the future for helicopters.
Obviously it only works for turbine helos and, so far, only on small to moderate sized airframes. Is there any reason why large, multi engine helos do not use it and what other disadvantages are there to NOTAR?
