  • Abstract Effect of Interactional
    ABSTRACT Title of thesis: EFFECT OF INTERACTIONAL AERODYNAMICS ON COMPUTATIONAL AEROACOUSTICS OF SIKORSKY'S NOTIONAL X2 PLATFORM Ian Kevin Bahr Master of Science in Aerospace Engineering, 2020 Thesis directed by: Professor James Baeder A. James Clark School of Engineering Department of Aerospace Engineering An in-house acoustics code, ACUM, was used in conjunction with full vehicle CFD/CSD coupling to create a computational aeroacoustic framework to investigate the effect of aerodynamic interactions on the acoustic prediction of a compound coaxial helicopter. The full vehicle CFD/CSD was accomplished by using a high- fidelity computational fluid dynamics framework, HPCMP CREATETM-AV Helios, combined with an in-house computational structural dynamics solver to simulate the helicopter in steady forward flight. A notional X2TD helicopter consisting of a coaxial rotor, airframe and pusher propeller was used and split into three simulation cases: isolated coaxial and propeller, airframe and full helicopter configuration to investigate each component's affect on the others noise as well as the total noise. The primary impact on the acoustic prediction was the inclusion of the airframe in the CFD simulation as it affected both coaxial rotors as well as the propeller. It was found that the propeller and coaxial rotors had negligible impact on each other.

  • Design and Performance of Lift-Offset Rotorcraft for Short-Haul Missions
    Design and Performance of Lift-Offset Rotorcraft for Short-Haul Missions Wayne Johnson Aeromechanics Branch National Aeronautics and Space Administration Ames Research Center, Moffett Field, California [email protected] Alex M. Moodie and Hyeonsoo Yeo Aeroflightdynamics Directorate (AMRDEC) U.S. Army Research, Development, and Engineering Command Ames Research Center, Moffett Field, California [email protected], [email protected] ABSTRACT The design and performance of compound helicopters utilizing lift-offset rotors are examined, in the context of short-haul, medium-size civil and military missions. The analysis tools used are the comprehensive analysis CAMRAD II and the sizing code NDARC. Following correlation of the comprehensive analysis with existing lift-offset aircraft flight test data, the rotor performance model for the sizing code was developed, and an initial estimate was made of the rotor size and key hover and cruise flight conditions. The rotor planform and twist were optimized for those conditions, and the sizing code rotor performance model updated. Two models for estimating the blade and hub weight of lift-offset rotors are discussed. The civil and military missions are described, along with the aircraft design assumptions. The aircraft are sized for 30 passengers or 6600 lb payload, with a range of 300 nm. Civil and military aircraft designs are described for each of the rotor weight models. Disk loading and blade loading were varied to optimize the designs, based on gross weight and fuel burn. The influence of technology is shown, in terms of rotor hub drag and rotor weight. and the rotor efficiency and lift capability steadily INTRODUCTION.

  • New Rotary Wing Technologies Dr Carlo Kopp
    New rotary wing technologies Dr Carlo Kopp Rotary wing technology like most aerospace technologies has evolved slowly since the end of the Cold War. Without the imperative of a well identified threat there has been little political or bureaucratic interest in maintaining the technological advantage the West held over all nations in 1991. heli & uv pacific 2010 At the end of the Cold War, the United States held a commanding advantage in most conventional rotary wing areas, with the Europeans lagging but closely behind, and the Soviets behind in all areas other than heavy lift helicopters. At that time the US had two new programs in development, the V-22 Osprey, which was to herald a generation of new tiltrotor technology designs, and the RAH-66 Comanche Scout helicopter which was to have been the vehicle for new rotor technologies, and a very low signature or ‘stealth’ design. Two decades later the Comanche is ‘dead’ and the V-22, after a very painful and protracted development cycle, is only now achieving credible operational maturity. Most of the military helicopter types remaining in production in the US are derivatives or variants of Cold War era designs. Europe is faring better, as it has a generation of new rotary wing designs now in production, using composite structural materials extensively, but these vehicles are in aerodynamic and propulsion Sikorsky X2. terms just as conventional as their trans-atlantic siblings.

The helicopter has carved a niche for itself as an efficient vertical take-off and landing aircraft, but have limitation on its cruising speed due to restrictions of retreating blade stall and advancing blade compressibility on the rotor in edgewise flight. This is a challenging task, which might be solved by the use of new design approach. It is believed that the application of a compound helicopter design concept would assist in achieving such a task. This paper describes an investigation aimed to examine the suitability of a compound helicopter design concept, allowing for the use of a combined conventional fix-wing aircraft with single propeller in the nose and conventional helicopter to satisfy the above objectives.

Ferguson∗, Douglas G. Thomsony, University of Glasgow, Glasgow, United Kingdom, G12 8QQ Compounding has often been proposed as a method to increase the maximum speed of the helicopter. There are two common types of compounding known as wing and thrust compounding. Wing compounding offloads the rotor at high speeds delaying the onset of retreating blade stall, hence increasing the maximum achievable speed, whereas with thrust compounding, axial thrust provides additional propulsive force. There has been a resurgence of interest in the configuration due to the emergence of new requirements for speeds greater than those of con- ventional helicopters. The aim of this paper is to investigate the dynamic stability characteristics of compound helicopters and compare the results with a conventional helicopter. The paper discusses the modeling of two com- pound helicopters, which are named the coaxial compound and hybrid compound helicopters. Their respective trim results are contrasted with a conventional helicopter model.

This increase in speed, provided efficient hover capability is maintained, would make the compound helicopter suitable for various roles and missions in both military and civil markets. The aim of this paper is to investi- gate the compounding of the conventional helicopter and how the addition of thrust and wing compounding influences the performance of this aircraft class. The paper features two compound helicopters. The first configuration features a coaxial rotor with a pusher propeller providing additional axial thrust, and is re- ferred to as the coaxial compound helicopter.

  • Performance and Hub Vibrations of an Articulated Slowed-Rotor Compound Helicopter at High Speeds
    Performance and Hub Vibrations of an Articulated Slowed-Rotor Compound Helicopter at High Speeds Jean-Paul Reddinger Farhan Gandhi Hao Kang Ph.D. Student Professor Research Engineer Rensselaer Polytechnic Institute Rensselaer Polytechnic Institute US Army Research Laboratory Troy, NY Troy, NY Aberdeen Proving Ground, MD ABSTRACT For a compound helicopter with an articulated main rotor, this study focuses on the high advance ratio, low disk loading environment of high speed flight at 225 kts. It seeks to understand the predominant phenomena which contribute to the main rotor power and hub vibrations, and demonstrate the most sensitive design and control criteria used in minimizing them for steady level flight—specifically the use of redundant controls and the effect of blade twist. The compound model is based on a UH-60A with 20,110 lbs of gross weight, and simulations are performed by Rotorcraft Comprehensive Analysis Sytem. The results show that for a −8◦ twisted rotor, the minimum power and minimum vibration states exist for two distinct sets of redundant controls and main rotor behavior. The low power state occurs at lower RPM and higher auxiliary thrust, with lower flapping and thrust at the main rotor. At a state with reduced vibrations, main rotor forward tilt, thrust, and average inflow ratio are higher, such that the rear of the rotor encounters less of the wake from the preceding rotor blades. For an untwisted rotor, it is shown that the regions for minimum power and minimum vibrations coincide with each other, with almost no flapping or pitch inputs and reduced rotor thrust from the twisted blade.

Helicopter – How it Works • Powered Rotor • Equal and opposite torque applied to rotor acts on fuselage Tail Rotor Rotor Thrust Thrust Main Rotor Drive Shaft Tail Boom Cockpit Tail Rotor Engine, Fuel, Landing Skids Transmission, etc. Controls Helicopter – Need for Anti-Torque • Engine fixed on body – exerts torque on rotor shaft – Rotor shaft exerts equal and opposite torque on body • Many configurations
