Anti -Torque system for MD500.

A question for the people who have flown the different types of 500's.
What are the handling characteristics for and against's for the normal two bladed tail rotor, four bladed (quiet tail rotor) and the NOTAR system.

2 bladed tail rotor very responsive, 4 bladed uses a bit more pedal, especially when heavy and high, really have to watch it then, notar no idea, apparently pretty fish tail like!!

2 blade tailrotor, lots of bite and very powerful
4 bladed maybe quiet but very expensive, not so much bite, engine off landings need a load more pedal as authority is not as good
Notar hm difficult to describe, put an input in and then wait for about 2 seconds for a response. In laymans terms think of it like the clutch in the car. Just before service the clutch travels along way to get the bite ( Notar)
Take car to garage, they adjust clutch / put new one in. Clutch now appears to be more like an on off switch than before ( 2 blade tailrotor)
Personally I would have the 2 bladed tail rotor everytime.

MD500 question

Gents,

On the 4-blade tail rotor for the MD500, what are the degrees in which the blades are spaced? I know for the Apache, it is 55/125. Any help is appreciated.

In the absence of a more accurate response, from the schematics the separation looks to be about 80, i.e. much wider than on the Apache (and than on the MELB, which uses a different close-coupled design with ~20 separation).

I/C

Fuel burn figure

A question for hughes 500

For the fuel burn figures on page 2 of this post was the airframe a C and the engine a C18 or c20.

Need a fuel burn for a C18 powered C model. Litres/kg/UK gals/US gals/lbs acceptable.

Thanks.

depends upon how power you are pulling. max cont cruise in a c18 normally about 18 gals hour, so you have about 2hr 30 to 2 hr 40 until empty
However this will depend upon how well blades are tracked, how good the compressr is and how good the turbine is !!

Most likely a pilot. The little birds fly with 2 pilots unless weight is a big issue for a specific mission.

Those things are beasts.

MELB Rotorhead.

The MELB has a six-blade rotorhead. It is being used on the new Boeing AH-6i gunship as well. It was mentioned a while back that the extra blade might not exactly be a step forward. Maybe it will be fitted with the original five-bladed head for the next upgrade.
