CarterCopters Cleaner Greener Your affordable environmentally-friendly VTOL technology Safer 2018 Carter Aviation Technologies, LLC
Carter Aviation 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 (SRC) 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!

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 Carter- Copter 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. 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 it s RPM to eliminate drag is what gives CarterCopters VTOL performance without the baggage. The 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 2. Transition: Aircraft accelerates & rotor RPM automatically begins to slow (no pilot input required). 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. 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. technologies involved?

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. why important?

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. Tourism Tourism may be one of the least Minor Injuries Serious Injuries Fatalities 21 12 23 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. avoid areas
Height (feet) Dead Man s Curve Helicopter Height Velocity Sample Diagram Must Avoid Regions Low Speed Region Takeoff Corridor High Speed Region Airspeed (knots) 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: A personal air vehicle (PAV) with point to point capabilities for the general population (like the Jetsons) is just around the corner. When you combine CarterCopter s inherent safety with the advances made with unmanned aerial vehicles (UAV) it makes for a personal air vehicle that grandparents will feel comfortable about flying to see their grandchildren rather than drive. The aircraft has the potential to very safely takeoff, fly (avoid other aircraft, restricted areas, weather) and land without any input from the pilot/passenger other than to enter the destination and OK the takeoff. Even if the passengers fall asleep and the aircraft runs out of fuel, the aircraft will pick an airport and land itself and if no airport is available, find a flat clear section of land to set down. in the end safety much better than an automobile. hear that?
Effective Perceived Noise Level (EPNdB) Acoustics Civil Helicopter Acoustic Requirements Cruise Airspeed S-92A Gross Weight (lbs) CarterCopter s Slowed- Rotor Compound Technology is 15-20 EPNdB quieter than the least noisy helicopters CarterCopters Clean and Quiet: 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. in summary
