ELECTRIC ROTARY WING AIRCRFTS. [3290] Field of invention relates to rotary wing aircrafts and the like. This invention relates to vertical propulsion turbine motors and generators combined including a digital glass cabin and manual navigation controllers consisting of a sphere or ball mounting in bearing in the stator casing and electrically connected with the flyby wire system. Helicopters and modern rotary wing aircraft and more particularly to helicopters with reduced blade length and increased speed and maneuverability with increased RPM. [3291] Combined propulsion and generator with linear rotors and perpendicular rotors. Helicopter in which in-plane Description of the prior art Sustainable and Zero emission helicopter with new means for navigating and power generating for electric flying vehicles. With wind turbines integrated in the duct and a steam turbine generator in a compressed machine casing electrically connected to the power supply. BACKGROUND OF THE INVENTION [3292] Conventional rotary wing aircraft are driven by combustion engines and are limited in application by rendering the aerial vehicles electric and digital with zero emission. Consisting rotary wing aircrafts ar helicopters and utility aerial vehicles, privet transport chopper, is a type of rotorcraft in which lift and thrust are supplied by propeller rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (Vertical Takeoff and Landing) aircraft cannot perform. The Electric aircraft is navigated by the main rotor and tail rotor and turbine engines and boosters comprising electric generators for power supply. -

Oil companies charter helicopters to move workers and parts quickly to remote drilling sites located at sea or in remote locations. His notes suggested that he built small flying models, but there were no indications for any provision to stop the rotor from making the craft rotate. During the closing years of the 20th century designers began working on helicopter noise reduction. Guinness World Record. Retrieved 24 September American inventor Arthur M. Tilts main rotor disk forward and back via the swashplate. From design, engineering and production, to maintenance, training and partnerships, Airbus is focused on meeting and exceeding industry safety standards and supporting the flight safety for the thousands of men and women around the world who are transported in its aircraft every day. Special jet engines developed to drive the rotor from the rotor tips are referred to as tip jets. These issues are due to the exposed tail rotor cutting through open air around rear of the vehicle. Most also have vibration dampers for height and pitch. For other uses, see Helicopter disambiguation. The rotor consists of a mast, hub and rotor blades. On 25 July , the Japanese bulk carrier Wakashio ran aground on a coral reef in Mauritius. Two Army National Guard helicopters flew low over the protesters, with the downward blast from their rotor blades sending protesters scurrying for cover and ripping signs from the sides of buildings. -

Ever since my first flight in a Boeing-737 when I was a child, I have dreamt about reaching for the skies, flapping my arms and soaring high above the earth. Flight had dawned mankind for many millennia, and has been at the forefront of my mind ever since my youth; and my first taste of it. In the words of Leonardo Da Vinci, I yearn to return. As such I have taken every step since my later school years developing the knowledge and expanding upon it. This thesis is dedicated to my family who have supported me so extensively throughout my early development and my schooling career. To my parents, Anthony and Karen Conaghan; without your constant love, support and guidance, I wouldn’t be the person I am today. I dedicate this work to you. -

The name of the helicopter derives from the Afrikaans word for "Red Falcon". The South African Air Force (SAAF) has ordered 12 Rooivalk AH-2As, the first of which entered service in July 1999. The helicopters are flown by 16 Squadron, which is based at AFB Bloemspruit near Bloemfontein. Due to the SAAF's decades of helicopter experience in the harsh African environment, the Rooivalk has been designed to operate in very basic surroundings for prolonged periods without sophisticated support. -

Design of a Helicopter Hover Test Stand
Design of a Helicopter Hover Test Stand A Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in Partial Fulfillment of the Requirements for the Degree of Bachelor Science in Aerospace Engineering by Bror Axelsson Jay Fulmer Jonathan Labrie March 6, 2015 Approved by: Professor Maria Chierichetti, Advisor Aerospace Engineering Program Aerospace Engineering Department, WPI Professor Anthony B. Linn, Co-Advisor Aerospace Engineering Program Aerospace Engineering Department, WPI Abstract The development of helicopter test stands allows for the testing and improvement of various components of helicopter rotor head and blade designs. The goal of this project is to design, build, and test a fully articulated helicopter rotor head system for future implementation on a hover test stand. The stand will be used to measure the forces and moments at the blade roots and the strain along the blades. The design of the rotor head is modular, allowing for the type and number of blades to be changed as desired without major disassembly of the test stand. The design is based on a fully articulated, four bladed rotor head with a custom fabricated swashplate and driveshaft. Additionally, a safety system was designed to ensure the safe operation of the hover test stand and protect the users in the case of failure at maximum rotor speed. The recommended data acquisition system for measuring stresses and strains is a light based system that uses fiber optic technology to accurately collect and transmit data from the -

The Pennsylvania State University The Graduate School College of Engineering THE EXPERIMENTAL INVESTIGATION OF A ROTOR ICING MODEL WITH SHEDDING A Thesis in Aerospace Engineering by Edward W. Brouwers © 2010 Edward W. Brouwers Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science May 2010 The thesis of Edward W. Brouwers was reviewed and approved* by the following: Jose L. Palacios Post Doctoral Research Associate Edward C. Smith Professor of Aerospace Engineering Thesis Adviser Cengiz Camci Professor of Aerospace Engineering George A. Lesieutre Professor of Aerospace Engineering Head of the Department of Aerospace Engineering *Signatures are on file in the Graduate School. ii ABSTRACT A critical operational problem for rotorcraft is flight in adverse weather conditions. Flight in icing conditions is fraught with operational hazards, including reduced vehicle performance and degraded handling qualities. Additionally, shedding of ice from blades due to centrifugal force poses a ballistics danger to the aircraft and creates large vibrations due to imbalanced rotors. Modeling the effects of accreted ice on rotorcraft flight performance has been a challenge due to the complexities of periodically changing conditions as well as spanwise variations of angle of attack, velocities and surface temperatures. Model validation has been complicated by the lack of available data due to the existence of only a few facilities designed to study the rotorcraft aspect of the icing problem. As part of the development of the Adverse Environment Rotor Test Stand (AERTS), a new icing model was developed to predict ice shapes on a hovering rotor. The AERTS Rotor Icing, Shedding and Performance (ARISP) model has the goal of exploring rotor icing trends. -
