Good strategy. The blades of a chopper are the most difficult to protect.

Combat chopper blades are designed to resist puncture damage, not sure if I know of what that are rated against blast damage.

The heat signature of the blades will also be significantly different from engine exhaust, which is what most MANPADs are designed to go for, and which traditional countermeasures are most focused against.

Thus decoys designed to mimic engine exhaust are going to be less effect against missiles designed to seek out the rotor blades.

The very fact the missile can home in on the rotor blades indicate an unusually high degree of sensitivity with the seeker.

The least protected part is also the most dangerous part if it is damaged or looses integratiy.

The entire Tailboom on every helicopter regardless of attack helicopter or civilian purposed have unarmored tails (tail boom). They are simply aluminium sheets, if explosion rips even a 30% hole in it, the integrity will be gone and the stress the tailrotor and torque of both main rotor aswell tailrotor shaft creates will rip it apart and helicopter aswell crew are lost.

Rotor blades are much harder to destroy. Missiles have very low payload to deliver, if it detonates beneath the rotor disc in between two rotor blades, most of the explosion and energy will not even hit the blades but just create a vibration, such vibrations have been spotted on Mi-8's in Afghanistan, they are very frightening to the pilots but often do not cause destruction of rotor blades. Those blades they used back then were not even armored or special durable rotor blades like are used today.

Would a continous-rod warhead be a good way to destroy rotor blades and/or the tailboom of a helicopter ?

The way I understand it, this kind of warhead creates an expanding circle that would hit the blades or the tail and should cut through them.

Imo, the rotor blades cutting through the shock waves, near or in the center of the explosion, would create an even greater reaction force that would damage the rotor blades even more than when they're stationary.
