  • USS George Washington (CVN 73) Comong into Port Everglades, FL
    NSUWorks, 2019
    Co-Authors: Courtesy Of The Naval Air Station Fort Lauderdale Museum
    Abstract:

    USS George Washington (CVN-73) is a United States Navy nuclear-Powered Aircraft carrier, the sixth carrier in the Nimitz class and the fourth US Navy ship named after George Washington, commander-in-chief of the Continental Army during the American Revolutionary War and the first president of the United States. The contract for George Washington was awarded to Newport News Shipbuilding on 27 December 1982. Her keel was laid on 25 August 1986, she was christened on 21 July 1990 by First Lady Barbara Bush, and she was commissioned at Naval Station Norfolk on 4 July 1992. In 2008, USS George Washington became the first nuclear Powered Aircraft carrier to be forward-deployed at naval base Yokosuka, Japan. Since August 2017, the carrier has been in her four-year Refueling and Complex Overhaul (RCOH), which is expected to be completed by August 2021.

  • USS Theodore Roosevelt (CVN-71) guided by Tug Boats in Port Everglades_FL
    NSUWorks, 2019
    Co-Authors: Courtesy Of The Naval Air Station Fort Lauderdale Museum
    Abstract:

    USS Theodore Roosevelt (CVN-71) is the fourth Nimitz-class, nuclear-Powered, Aircraft carrier in the United States Navy. She is named in honor of Theodore Roosevelt, the 26th President of the United States and a proponent of naval power. She is the fourth ship named in honor of Theodore Roosevelt, three bearing his full name and a fourth with just his last name. Another three U.S. Navy ships have Roosevelt in their names in honor of members of the Roosevelt family. This carrier\u27s radio call sign is Rough Rider , the nickname of President Roosevelt\u27s volunteer cavalry unit during the Spanish–American War. She was launched in 1984 and saw her first action during Operation Desert Storm in 1991. Wikipediahttps://nsuworks.nova.edu/nasfl_ships/1182/thumbnail.jp

  • joint optimization of battery mass and flight trajectory for high altitude solar Powered Aircraft
    Proceedings of the Institution of Mechanical Engineers Part G: Journal of Aerospace Engineering, 2014
    Co-Authors: Xianzhong Gao, Zhongxi Hou, Zheng Guo, Xiaoqing Chen, Xiaoqian Chen
    Abstract:

    The design parameters of high-altitude solar-Powered Aircraft are highly correlative with its flight trajectory. However, it is not an easy work to jointly optimize them in the concept design stage. This paper considers the joint optimization problem of battery mass and flight trajectory for high-altitude solar-Powered Aircraft. The system model including the Aircraft dynamic model, aerodynamic parameters, and thrust model is presented. Then the problem to be optimized is formulated and a new optimization method, which uses the particle swarm optimization and Gauss pseudo-spectral method, is proposed. The Gauss pseudo-spectral method is employed to generate the minimal power consumed by following the flight trajectory in the given configuration of high-altitude solar-Powered Aircraft, while the particle swarm optimization is used to calculate the optimal battery mass of Aircraft. The simulation result shows that the proposed joint optimization method can reduce the battery mass of high-altitude solar-Powered Aircraft from 16?kg to 13.6?kg, which is equivalent to enhancing its energy density by 19.7%. It can be also seen that the proposed optimization method connects each parameter in a logically clear way and hence provide a perspective for understanding the optimization problem.

  • the equivalence of gravitational potential and rechargeable battery for high altitude long endurance solar Powered Aircraft on energy storage
    Energy Conversion and Management, 2013
    Co-Authors: Xiaoqian Chen
    Abstract:

    Abstract Applying solar energy is one of the most promising methods to achieve the aim of High-altitude Long-endurance (HALE) flight, and solar-Powered Aircraft is usually taken by the research groups to develop HALE Aircraft. However, the crucial factor which constrains the solar-Powered Aircraft to achieve the aim of HALE is the problem how to fulfill the power requirement under weight constraint of rechargeable batteries. Motivated by the birds store energy from thermal by gaining height, the method of energy stored by gravitational potential for solar-Powered Aircraft have attracted great attentions in recent years. In order to make the method of energy stored in gravitational potential more practical in solar-Powered Aircraft, the equivalence of gravitational potential and rechargeable battery for Aircraft on energy storage has been analyzed, and four kinds of factors are discussed in this paper: the duration of solar irradiation, the charging rate, the energy density of rechargeable battery and the initial altitude of Aircraft. This work can provide some governing principles for the solar-Powered Aircraft to achieve the unlimited endurance flight, and the endurance performance of solar-Powered Aircraft may be greatly improved by the application of energy storage using gravitational potential.

  • energy management of solar Powered Aircraft based high altitude platform for wireless communications
    Electronics, 2020
    Co-Authors: Steve Chukwuebuka Arum, David Grace, Paul D Mitchell, Muhammad D Zakaria, Nils Morozs
    Abstract:

    With the increasing interest in wireless communications from solar-Powered Aircraft-based high altitude platforms (HAPs), it is imperative to assess the feasibility of their deployment in different locations with the constraints on energy consumption and payload weight under consideration. This paper considers the energy management of solar-Powered Aircraft-based HAPs for wireless communications service provisioning in equatorial regions and regions further up the northern hemisphere. The total solar energy harvested and consumed on the shortest day of the year is analyzed, and it is explained how this determines the feasibility of long endurance, semi-permanent missions. This takes into account the different Aircraft-based HAPs and the energy storage systems currently available, and how these can be deployed for wireless communications. We show that the solar-Powered HAPs are energy and weight limited, and this depends largely on the platform’s wingspan available for the deployment of solar collectors. Our analysis show that services can be provided for a duration of 15–24 h/day using current platforms, with wingspans ranging between 25–35 m, depending on the configuration and coverage radius. Furthermore, we show that doubling an Aircraft’s wingspan can increase its payload capacity by a factor of 6, which in turn enhances its feasibility for wireless communications.
