Carter Aviation
Founded in 1994
Is a green VTOL possible?
Genesis & Mission:
The company has its roots in the wind industry. In the late 70s
and early 80s, Carter Wind Systems developed the most
efficient wind turbine of its time. The key enabler was the
very lightweight high inertia wind turbine blades. This same
core technology is a critical enabling element of Carter’s Slowed-Rotor/Compound
(SR/C™) technology. Jumpstarted by the
success in the wind industry, Carter
Aviation was founded with the mission to
develop breakthrough vertical-lift technology – Technology aimed at providing the
world’s safest and most efficient and
environmentally friendly runway independent aircraft ever conceived.
…and they did it!

CarterCopter Stands Out:
All aircraft have varying levels of potential across a
variety of assessment factors. From speed to hover and
cruise efficiency, the CarterCopter hits them all. No
other technology provides the level of performance,
level of safety, and ease of operation in a single
platform. All of this in a cleaner and more cost effective
design. Because of these characteristics, the CarterCopter will emerge in the future as the aircraft of
choice. 20 years in the making, this runway independent technology offers the freedom of VTOL operations
with the speed and efficiency of conventional fixedwing aircraft, but delivers this performance at an
affordable price. No other technology has achieved
this.

It’s all about Drag Reduction
CarterCopter is a simple
fixed-wing aircraft first
Rotor added for vertical
takeoff & landing
Rotor RPM greatly
reduced for cruise
CarterCopter Slowed Rotor:
The slowing of the rotor all but eliminates its contribution to
drag in cruise flight and thus you’re back to a pure fixed-wing
aircraft with all the performance benefits and efficiencies. The
addition of the rotor and the subsequent slowing of its RPM to
eliminate drag is what gives CarterCopters VTOL performance
without the baggage. That baggage being the debilitating
impact of an open rotor system in forward flight with all of its
associated drag and cruise inefficiency.
…how’s it transition?
Seamless Transition from
Vertical to Translational Flight
4. Landing: Rotor RPM automatically speeds up as aircraft
decelerates for landing. Pilot
performs simple flare to arrest
the sink rate and perform a
zero-roll landing.
2. Transition: Aircraft
accelerates & rotor RPM automatically begins to slow (no
pilot input required).
3. Cruise: Rotor continues to
slow automatically to the
minimum stable RPM with
wings providing 90% of the lift.
1. Takeoff: Rotor is pre-rotated on the
ground then disengaged for takeoff. A
simple button press and the aircraft
automatically jumps off the ground and
begins to climb and accelerate.
Pilot
maintains throttle setting and aircraft pitch
like a conventional fixed-wing aircraft.
CarterCopter Flying Characterics:
CarterCopters are designed to fly generally like conventional
general aviation aircraft. With the exception of pre-rotating
the rotor in preparation for a vertical takeoff, airmanship and
handling of the aircraft will be familiar to fixed-wing pilots.
This has been achieved by fully automating aspects of the
aircraft control specific to the vertical flight elements and
transition to wing borne flight.

CarterCopter Soars:
CarterCopters are equipped with an ultra high inertia rotor
that generates tremendous energy. It is this energy that is harvested to perform safe zero roll landings time after time. For
the world’s helicopter fleet, landing on rotor energy alone is an
emergency procedure and can result in significant damage to
the aircraft or worse. CarterCopter rotor technology makes
these landings routine.

…more on safety
Safety
Helicopter vs Fixed-wings:
Helicopter manufacturers have long claimed safety advantages
over fixed-wing aircraft. The basis of the claim is that a helicopter can land practically anywhere since it can autorotate
and doesn’t require a runway. While this is true, successfully
performing an autorotation in the real world typically results in
substantial damage to the aircraft, banged up occupants or
worse. The general safety record of helicopters is more
troubling.

one of the least
demanding helicopter missions, but it is not
without issues. A study summarized accidents in Hawaii from ’90-2011. There were
25 accidents & more than 1 fatality per year.
CarterCopter Safety Trumps Them All:
CarterCopters have the same advantages of helicopters over
fixed-wings, but with a critical exception – CarterCopters have
enough rotor energy to make a normal landing after an engine
failure – No other flying machine ever devised can make this
claim. Unique technology with exceptional safety.

CarterCopters Safe at all Speeds & Altitudes:
All helicopters have height-velocity diagrams often referred to
as ‘dead man’s curves.’ Although within the helicopter safe
flight envelope, these airspeed and altitude combinations
must be avoided. If the aircraft has a failure requiring an
autorotation while in one of these regions, recovery will not be
possible. CarterCopters have no avoid regions within the
flight envelope nor a stall speed since lift seamlessly shifts
between wing and rotor throughout all speeds regimes.
CarterCopters – Cleaner, Greener, & Safer.
…hard to fly?
Simple to Fly
CarterCopters are Simple to Fly:
An affordable personal air vehicle (PAV) with point to point
capabilities for the general population is just around the
corner. Rotor pitch control, referred to as collective in
helicopters, is automated so a helicopter pilots license is not
required. With every landing an autorotation, there is no need
to obtain special training to land in the event of engine failure.
With straightforward general aviation aircraft controls, a fixedwing pilots license with gyro add on is all that is required. Easy
and safe to operate, the PAV is poised to change aviation
forever.

CarterCopters Clean and Quiet:

Technology is 15-20
EPNdB quieter than the

Recall that CarterCopters are essentially a fixed-wing aircraft.
As such, they possess fixed-wing acoustic characteristics.
Unlike helicopters where the rotor is loaded and therefore
noisy throughout the flight envelope, CarterCopters cruise
quietly, cleanly, and efficiently through the skies.
