How Does the ACA Hurricane Work?

swing down feature??? whats that?

Albeit a somewhat crude drawing of it, here's what the swing-down feature on a pole mounted Hurricane-130 would look like:

They also offered three rotor configurations: 8/10 (most common), 8/12 (sounds like a Cyclone), and 10/12 (sounds like a 2T22). Perhaps they also offered single-tone units with one's choice of rotors.

According to both the 130 and MKII manuals, they were also offered in 8, 10, or 12 port dual rotors, as well as the 8/10(standard), 8/12, and 10/12 rotor configurations, as you aforementioned.

1. A one-horsepower motor with a small load, which runs on single-phase power (I'm not talking about the blower-motor Rolling Eyes ) is going to wind up very fast.

I don't follow. The Thunderbolt's chopper motor is a two-horsepower, single phase motor.

But based on this thread and my question in the other thread, I'm willing to chalk it up to the hurricane using an induction motor at lower peak speed vs. the Tbolt's universal motor at a higher peak speed.

I'm not saying that all smaller motors will wind up very fast, but allot do.

Work load has a factor in wind-up speed too. I have a 1-2 HP 120/240VAC motor just sitting around and it winds up in a split second with no load, but when we had it mounted in the big belt-driven industrial circulation fan that we used to have, it wound up slower, because of the big load on the motor. Same goes with my smaller 1/8HP 120VAC bathroom fan motor that I have (as seen in my "Thunderbolt Rotator Question" video).

Oh yeah, the choppers in hurricanes weigh NOTHING. I remember spinning Garland's over by hand. Probably a quarter the weight of a T-Bolt's. That, and an induction motor takes much less time to come to a defined peak speed than a universal. Universal motors just keep winding up until they're happy with the voltage they're getting.
The blowers wind up quick too. It has a monster motor contactor, and the blower rotors weigh nothing too. All aluminum.
