Cartercopters CarterCopters • Cleaner Your affordable environmentally-friendly • Greener VTOL technology • Safer © 2015 – Carter Aviation Technologies, LLC 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 ele- ment 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 techno- logy – Technology aimed at providing the world’s safest and most efficient and environmentally friendly runway indepen- dent aircraft ever conceived. …and they did it! *SR/C is a trademark of Carter Aviation Technologies, LLC Technology Comparisons Assessment Factors Ducted Fan Helicopter Tiltrotor Fixed-Wing CarterCopter Speeds beyond 350 kts Hover Efficiency N/A Cruise Efficiency Engine Out Safety Stall Characteristics Easy to Fly Ease of Obtaining License Autonomous Potential 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 Carter- Copter will emerge in the future as the aircraft of choice. 20 years in the making, this runway indepen- dent technology offers the freedom of VTOL operations with the speed and efficiency of conventional fixed- wing aircraft, but delivers this performance at an affordable price. No other technology has achieved this. …how developed? CarterCopters: Green Technology of Tomorrow Available Today!

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 4.

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?

The basis of the claim is that a heli- copter 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.

A study summarized acci- dents 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.

  • Effectiveness of the Compound Helicopter Configuration in Rotorcraft Performance Increase
    transactions on aerospace research 4(261) 2020, pp.81-106 DOI: 10.2478/tar-2020-0023 eISSN 2545-2835 effectiveness of the compound helicopter configuration in rotorcraft performance increase Jarosław stanisławski Retired doctor of technical sciences [email protected] • ORCID: 0000-0003-1629-4632 abstract The article presents the results of calculations applied to compare flight envelopes of varying helicopter configurations. Performance of conventional helicopter with the main and tail rotors, in the case of compound helicopter, can be improved by applying wings and pusher propellers which generate an additional lift and horizontal thrust. The simplified model of a helicopter structure, consisting of a stiff fuselage and the main rotor treated as a stiff disk, is applied for evaluation of the rotorcraft performance and the required range of control system deflections. The more detailed model of deformable main rotor blades, applying the Galerkin method, is used to calculate rotor loads and blade deformations in defined flight states. The calculations of simulated flight states are performed considering data of a hypothetical medium class helicopter with the take-off mass of 6,000kg. In the case of both of the helicopter configurations, the articulated main rotor hub is taken under consideration. According to the Galerkin method, the elastic blade model allows to compute blade deformations as a combination of the blade bending and torsional eigen modes. Introduction of additional wing and pusher propellers allows to increase the range of operational speed over 300 km/h. Results of the simulation are presented as time- runs of rotor loads and blade deformations and in a form of disk distribution plots of rotor parameters.

Abstract The desire for a vertical takeoff and landing (VTOL) aircraft capable of high forward flight speeds is very strong. Compound lift-offset coaxial helicopter designs have been proposed and have demonstrated the ability to fulfill this desire. However, with high forward speeds, noise is an important concern that has yet to be thoroughly addressed with this rotorcraft configuration. This work utilizes a coupling between the Rotorcraft Comprehensive Analysis System (RCAS) and PSU-WOPWOP, to computationally explore the acoustics of a lift-offset coaxial rotor sys- tem. Specifically, unique characteristics of lift-offset coaxial rotor system noise are identified, and design features and trim settings specific to a compound lift-offset coaxial helicopter are considered for noise reduction. At some observer locations, there is constructive interference of the coaxial acoustic pressure pulses, such that the two signals add completely. The locations of these constructive interferences can be altered by modifying the upper-lower rotor blade phasing, providing an overall acoustic benefit.

  • DYNAMIC MODELING of AUTOROTATION for SIMULTANEOUS LIFT and WIND ENERGY EXTRACTION by SADAF MACKERTICH B.S. Rochester Institute O
    DYNAMIC MODELING OF AUTOROTATION FOR SIMULTANEOUS LIFT AND WIND ENERGY EXTRACTION by SADAF MACKERTICH B.S. Rochester Institute of Technology, 2012 A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in the Department of Mechanical and Aerospace Engineering in the College of Engineering and Computer Science at the University of Central Florida Orlando, Florida Spring Term 2016 Major Professor: Tuhin Das c 2016 Sadaf Mackertich ii ABSTRACT The goal of this thesis is to develop a multi-body dynamics model of autorotation with the objective of studying its application in energy harvesting. A rotor undergoing autorotation is termed an Autogyro. In the autorotation mode, the rotor is unpowered and its interaction with the wind causes an upward thrust force. The theory of an autorotating rotorcraft was originally studied for achieving safe flight at low speeds and later used for safe descent of helicopters under engine failure. The concept can potentially be used as a means to collect high-altitude wind energy. Autorotation is inherently a dynamic process and requires detailed models for characterization. Existing models of autorotation assume steady operating conditions with constant angu- lar velocity of the rotor. The models provide spatially averaged aerodynamic forces and torques. While these steady-autorotation models are used to create a basis for the dynamic model developed in this thesis, the latter uses a Lagrangian formulation to determine the equations of motion. The aerodynamic effects on the blades that produce thrust forces, in- plane torques, and out-of-plane torques, are modeled as non-conservative forces within the Lagrangian framework.

The objective of this work is to develop a real-time system which provides full autonomous control for autorotation landing of helicopters. The work includes the development of an autorotation path planning method and integration of the path planner with a primary flight control system. The trajectory is divided into three parts: entry, descent and flare. Three different optimization algorithms are used to generate trajectories for each of these segments. The primary flight control is designed using a linear dynamic inversion control scheme, and a path following control law is developed to track the autorotation trajectories. Details of the path planning algorithm, trajectory following control law, and autonomous autorotation system implementation are presented.

  • Interagency Helicopter Pilot Practical Test Standards 2015
    Interagency Helicopter Pilot Practical Test Standards 2015 Version 2.0 Blank Page Version 2.0 INTRODUCTION Practical Test Standards Concept A Federal Aviation Administration (FAA) commercial pilot certificate or airline transport pilot-helicopter certificate has been identified as the minimum pilot performance standard for interagency Government pilots and interagency vendor pilots. The standards required to obtain an FAA pilot certificate are outlined in the FAA’s Practical Test Standards (FAA PTS). Some flight missions called for by interagency pilot mission statements, interagency contracts, and/or aircraft rental agreements call for pilot skills and proficiency not covered by the FAA PTS. The Interagency Practical Test Standards (IPTS) is a supplement to the FAA PTS. This standard identifies and establishes the additional pilot knowledge and skills that are expected for each specific interagency helicopter pilot qualification for day, night, and night vision goggle (NVG) operations. Any Variation or Deviation from the standards in this document must have prior approval in writing from the National Helicopter Specialist (OAS) and/or the National Helicopter Standardization Pilot (USFS). The content of this IPTS includes a combination of requirements for interagency helicopter pilot qualification, a matrix of interagency mission titles, and a set of definitions for the terms that are unique to interagency operations. Any task not included in this package will be found in the FAA PTS. All applicable FAA practical test standards are incorporated by reference into this IPTS. The IPTS is a dynamic document to be reviewed annually and updated as needed. Please forward suggested changes to [email protected]. When changes occur, the document’s revision history log will reflect an updated version number, date, and change description.
