Here is some thoughts.
The Advantages of Turbo-Normalizing
Normally aspirated engines suffer from reduction of manifold pressure as
they climb, which pilots compensate for by pushing in the throttle. At
about 7,500 feet the engine runs "out of throttle". As the altitude
increases, the manifold pressure decreases and the plane slows. Flying
higher becomes more and more inefficient.
With a turbo-normaling system providing sea level air pressure for
combustion all the way to high altitude, the loss of power and speed is
delayed until reaching "the critical altitude". With the my Turbo system,
critical altitude is 20,000 feet, or so. Advantageously, the air speed
increases as the skin friction of thinner air density decreases. High
altitude capability allows the pilot the choice of:
a.. Topping the weather
b.. Avoiding turbulence
c.. Maintaining terrain clearance over mountains
d.. Seeking more favorable headwinds
e.. Catching tail winds
f.. More enjoyable clear air and sunshine
g.. Navigation and communications is better --- longer line of sight
h.. Obstacle clearance and mountain turbulence, generally 10,000 ft in the
East and 16,000 feet in the West.
i.. Safety advantage of altitude: 12,500 to 17,500 have least traffic
j.. Added safety in an emergency from greater glide time. Area for
landing increases as the square of the range
At 6,000' glide is about 7 minutes, 12.5 miles
At 12,000' glide is about 14 minutes, 25 miles
At 18,000' glide is about 21 minutes, 37.5 miles
Faster speeds mean less engine time, less avionics time and the probability
of less maintenance
Faster speeds mean greater range with the same amount of fuel
High flight makes available smoother ride, colder air -- less icing risk
[ I am also using fuel injection and ECU to manage the timing and
pre-detonation problem.]
That's my thoughts.
