  • Assessment Method of Fuel Consumption and Emissions of Aircraft During Taxiing on Airport Surface Under Given Meteorological Conditions
    sustainability Article Assessment Method of Fuel Consumption and Emissions of Aircraft during Taxiing on Airport Surface under Given Meteorological Conditions Ming Zhang * , Qianwen Huang, Sihan Liu and Huiying Li College of Civil Aviation, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China; [email protected] (Q.H.); [email protected] (S.L.); [email protected] (H.L.) * Correspondence: [email protected] or [email protected] Received: 27 September 2019; Accepted: 31 October 2019; Published: 2 November 2019 Abstract: Reducing fuel consumption and emissions of aircrafts during taxiing on airport surfaces is crucial to decrease the operating costs of airline companies and construct green airports. At present, relevant studies have barely investigated the influences of the operation environment, such as low visibility and traffic conflict in airports, reducing the assessment accuracy of fuel consumption and emissions. Multiple aircraft ground propulsion systems on airport surfaces, especially the electric green taxiing system, have attracted wide attention in the industry. Assessing differences in fuel consumption and emissions under different taxiing modes is difficult because environmental factors were hardly considered in previous assessments. Therefore, an innovative study was conducted based on practical running data of quick access recorders and climate data: (1) Low visibility and taxiing conflict on airport surfaces were inputted into the calculation model of fuel consumption to set up a modified model of fuel consumption and emissions. (2) Fuel consumption and emissions models under full- and single-engine taxiing, external aircraft ground propulsion systems, and electric green taxiing system could accurately estimate fuel consumption and emissions under different taxiing modes based on the modified model.

  • The Role for Federal R&D on Alternative Automotive
    THE ROLE FOR FEDERAL R&D ON ALTERNATIVE AUTOMOTIVE POWER SYSTEMS by John B. Heywood Henry D. Jacoby Lawrence H. Linden MIT Energy Laboratory Report No. MIT-EL 74-013 November 1974 Contract No. EN-44166 Report # MIT-EL 74-013 REPORT SUBMITTED TO: THE OFFICE OF ENERGY R & D POLICY NATIONAL SCIENCE FOUNDATION by the ENERGY LABORATORY Massachusetts Institute of Technology Cambridge, Massachusetts THE ROLE FOR FEDERAL R & D ON ALTERNATIVE AUTOMOTIVE POWER SYSTEMS prepared by John B. Heywood Henry D. Jacoby Lawrence H. Linden with the assistance of Patricia D. Mooney Joe M. Rife November 1974 4 i EXECUTIVE SUMMARY Within the past few years, reductions in air pollutant emissions and fuel consumption of the U.S. passenger car fleet have become important public policy goals. The automobile manufacturers have responded to government regulation or changing market pressures in these areas by modifying the internal combustion engine (ICE), the powerplant which has dominated the passenger car application for almost sixty years. There are, however, alternatives to the ICE which may offer substantial improvements in emissions and fuel economy, but to many people the industry appears reluctant to deal seriously with them, and a Federally sponsored research and development (R & D) program has been called for. This report examines the question: Is it appropriate for the Federal Government to support R & D on alternative automotive powerplants? This issue is highly controversial. Some argue that emissions regulations and the high level of importance given to fuel economy by car buyers give the manufacturers strong and clear incentives for improvements in these areas.

Supplementary Notes 16. Abstract Research shows that air pollution caused by a large airport could be equivalent to that produced by many hundreds of miles of freeway traffic. Airplane air pollution include ultrafine sulfur dioxide, nitrogen oxide and other toxic particles, which not only affect employees and passengers on airport and residents near airport but could spread to as far as 10 miles and cause health concerns of a significant amount of population.

  • Case Study on HYBRID VEHICLES Power Vehicle Type
    Case Study on HYBRID VEHICLES Power Power sources for hybrid vehicles include: Coal, wood or other solid combustibles Compressed or liquefied natural gas Electricity Electromagnetic fields, Radio waves Electric vehicle battery Human powered e.g. pedaling or rowing Hydrogen On-board or out-board rechargeable energy storage system (RESS) Petrol or Diesel fuel Solar Wind Vehicle type Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, as power is delivered both via an internal combustion engine or electric motor and the rider's muscles. Early prototypes of motorcycles in the late 19th century used the same principles to power it up. In a parallel hybrid bicycle human and motor power are mechanically coupled at the pedal drive train or at the rear or the front wheel, e.g. using a hub motor, a roller pressing onto a tire, or a connection to a wheel using a transmission element. Human and motor torques are added together. Almost all manufactured Motorized bicycles, Mopeds are of this type. In a series hybrid bicycle (SH) the user powers a generator using the pedals. This is converted into electricity and can be fed directly to the motor giving a chainless bicycle but also to charge a battery. The motor draws power from the battery and must be able to deliver the full mechanical torque required because none is available from the pedals. SH bicycles are commercially available, because they are very simple in theory and manufacturing. The first known prototype and publication of an SH bicycle is by Augustus Kinzel (US Patent 3'884'317) in 1975.

Many regulatory bodies results in larger airline fleets every year. The aircraft market agreed to limit the environmental impact of this growth by forecast reveals an unprecedented growth for the coming decades, imposing common targets, such as 1) reduction of CO2 leading to serious environmental and economic concerns among emissions for 75% per passenger kilometre, 2) 90% decreasing airlines and regulatory bodies. Different approaches, for both of NO emissions, and 3) minimization of noise, as presented in airborne and ground operations, have been proposed to reduce x Flight Path 2050 strategy. All the aimed reductions are referred and control emissions without compromising profit margin. For on-ground activities, the electric taxiing (ET) methodology is one to the levels recorded in 2000 [7]. of the suggested solutions for reducing the emissions and the Aviation fuel typically comprises 25% or more of airline acoustic noise in the airport, and for lowering the fuel costs and, it accounts for over 97% of airline CO2 emissions [8]. consumption and operating costs.

  • DLR Airbus A320 ATRA Taxis Using Fuel Cell-Powered Nose Wheel for the First Time
    DLR Airbus A320 ATRA taxis using fuel cell-powered nose wheel for the first time 06 July 2011 DLR and Airbus test electric nose wheel in taxiing test at Hamburg airport On 30 June 2011, DLR’s A320 ATRA (Advanced Technology Research Aircraft) taxied around Hamburg Finkenwerder Airport propelled by an electric nose wheel. In the taxiing tests, researchers and engineers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), Airbus and Lufthansa Technik demonstrated a fuel cell-powered electric nose wheel. When installed in airliners, such nose wheels could significantly reduce noise and emissions at airports. Up to 19 percent savings in pollutant emissions while on the ground An airliner fitted with a fuel cell-powered nose wheel can, for example, move from its stand to the end of the runway without emitting pollutants and without using its engines. "This means that up to 17 to 19 percent of the emissions produced in airports can be saved and almost all noise can be eliminated during taxiing," explained project leader Josef Kallo from the DLR Institute of Technical Thermodynamics (Institut für Technische Thermodynamik) in Stuttgart. DLR is still working on detailed models for the calculation of potential savings at airports. “The potential saving at Frankfurt Airport from the use of electrically-driven nose wheels for Airbus A320 class aircraft is about 44 tons of kerosene per day,” said Thorsten Mulhouse from the DLR Institute of Flight Guidance (Institut für Flugführung). The fuel cell system installed on the ATRA for the tests delivers enough electrical power to move the 47-ton aircraft across the apron.
