Hello fellow Travellers,
here are some more complaints about FF&S:
1. A serious question to GDW: I though NOTaR is a Trademark of Hughes/
McDonnel Aircraft corporation. Is this true ?
2. What about wingtip powered rotors ? They do not need any counter torque
rotor. All those alternative technology, and such an easy variant of
rotors is not available ?
3. High and Ultra High bypass Turbofans are easily available today. What I
cannot understand is the low weight to thrust ratio of the engines you
show in the design table (p.70). A thrust of three tons for 1 ton of
engine mass is indeed not state of the art today. What about this:
TL Type Th MCr MaxT FC FT Airframe
8 UHBT 10 0.0800 100 0.09 HCD Fast Supsonic
I think this will fit to the engines used on an Airbus A330.
This engine is build for best performance at subsonic speeds!
4. What does EAPlaC mean ? A solid fuel technology I assume ?
5. I thought MHD is a method of moving a ship. Is it possible to
use the method the other way around ? I wonder because MHD is
counted as chemical power plant (p.63).
6. Why is the Glide ratio for Helicopters treated as nil ? The autorotation
is similar to the method of flying an autogiro use.
7. Do workstations include the weight of the operator ?
I hope I can do some designs soon...perhaps I can go around some of
my troubles with the FF&S rules.
