Melmoth 2

The guy who designed and built this plane has a cool life. His name is Peter Garrison, he writes for flying magazine and built this experimental aircraft.

This is a really cool plane if you understand home building, or actually there are not many manufactured planes that perform like this aircraft. Look at it's cruising speed 170 kt at 55% power@8.2 gph, and has a rate of climb of 1,900 fpm. I may just have to build this as a 50% or 60% plane one day.

Performance

Most of the values below are calculated on the basis of other observations; [C] indicates a calculated item.

At 2,100 pounds (eg, two persons, 40 gallons of fuel)

Maximum cruising speed (75% power at 18,000 feet) 200 kt @ 11 gph [C]
Economical cruising speed (55% power at 12,000 feet) 170 kt @ 8.2 gph
Rate of climb (sea level) 1,900 fpm @ 95 kias
Takeoff distance (sea level) 700 ft. [C]
Range with 45 minute reserve at 55% power 640 nm [C]

At 2,850 pounds (eg, three persons, 142 gallons of fuel)

Maximum cruising speed (75% power at 18,000 feet) 193 kt @ 11 gph [C]
Economical cruising speed (55% power at 12,000 feet) 163 kt @ 8.2 gph [C]
Rate of climb (sea level) 1,270 fpm @ 100 kias [C]
Takeoff distance (sea level) 1,300 ft. [C]
Range with 45 minute reserve at 55% power 2,690 nm [C]

 

Permission from Peter Garrison was given to AA to display these pictures.

(How cool is that!)

 

 

Cool parts

Cool flap design. On most aircraft the flap track is on the bottom of the wing, in this design it is on top.

Very cool cowl flaps (open)

Very cool cowl flaps (closed)

Home built, how cool can you get.

I thought I had it good, this is Peter Garrison, he flies, he writes about flying, and he flies what he has built.
