Experimental H2 [H2](hydrogen fuel cell) powered Gavin Hawks


  • Start with:


    Liquid hydrogen:

    "Fuel-cell cars — which run on hydrogen and emit only water from their tailpipes — offer a compelling way to reduce transport emissions. However, manufacturers have struggled to find ways of safely storing enough hydrogen in a car for long journeys.

    Researchers have now taken a step towards an alternative: storing the hydrogen as a liquid. University of Oregon chemist

    Shih-Yuan Liu and colleagues report the creation of a new material: BN-methylcyclopentane, a five-membered cyclic amine borane that is a stable liquid at room temperature and pressure.

    When a cheap iron chloride catalyst is added, three of these rings chemically join together, releasing hydrogen in the process.

    Liu’s work was funded by a US Department of Energy project that is aiming to develop a viable liquid or solid storage mechanism for hydrogen fuel by 2017. The team is now working to make recycling of their starting material cheaper and more energy efficient."

  • Based on the following developments by Boeing:

    "Boeing researchers and industry partners throughout Europe conducted experimental flight tests in February 2008 of a manned airplane powered only by a fuel cell and lightweight batteries. The Fuel Cell Demonstrator Airplane, as it was called, used a Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor, which was coupled to a conventional propeller.[59] In 2003, the world's first propeller driven airplane to be powered entirely by a fuel cell was flown. The fuel cell was a unique FlatStackTM stack design which allowed the fuel cell to be integrated with the aerodynamic surfaces of the plane.[60] "

    RDL proposes designing and building experimental versions of GavinSuperSeaHawk [eGSSH2] with a similar hydrogen fuel cell engine,similar to the above mentioned Boeing aircraft, driving a propeller, and an electrically powered rotor designed for (occasional) vertical take-off  and landing.

  • The first version of eGSSH2.1 is a 1/10th sized version of the GSSH2,  also including an autopilot designed to be operated by a land-based PATC team.

  • The GSSH2 has been described on Gavin Hawk as a:

    "GavinSuperHawk MK1 [GSH1]-- 1-to-10 passenger piloted autogyro, similar to: http://www.cartercopters.com/nxcc.htmlGavin Super Hawks are equipped to carry Metal Storm Advanced Weapons [MSAW] and/or GiaBats, including SuperGiaBats. MSAWs use two types:

    1. 10 multiple barrels, stacked with 9mm bullets, and/or
    2. 10 multiple barrels, stacked with 40mm rocket-propelled grenades.

    Each type is capable of firing up-to one million bullets/minute, and are provided for advanced defense of large flocks of Gavin Hawks from attack by:

    1. aircraft for ramming and/or
    2. firing cannon
    3. machine guns
    4. air-to-air rockets and/or
    5. ground based ground-to-air rockets.
  • Gavin Super Hawk MK2 [GSH2]-- 0-to-10 passenger, pilot less autogyro, otherwise similar to just above, and (optionally)equipped with an electric drive for the rotor to allow vertical takeoff and landing.
  • Gavin SuperSea Hawk MSK2 [GSSH2] -- 0-to-10 passenger, pilot-less autogyro, similar to the GSH1 (and GSH2 above, but not necessarily equipped with an electric drive for the rotor (to allow vertical takeoff and landing) but otherwise the same. The GSSH2 hull is always designed to be able to land or takeoff directly on water, and can also be equipped to takeoff and land, on land, instead; and also, optionally, vertically, or on a short (100'-to250') landing strip."
  • The 1/10th size Experimental Gavin Super Sea Hawk [eGSSH2.1] Shall be produced in a double garage, or similar enclosed area, and controlled, initially by a ground based PATC from a base on land, ship or vehicle, up-to-0-to-200 miles from its intended flight area. Based on eGSSH2.1 design, development and trials, similar work on experimental versions of other Gavin Hawks [GH] will be accomplished in a similar manner.

  • H2, planned by RDL, includes:  The first version of eGSSH2,  an unweaponized,a 1/10th sized version of the  GSSH2, Gavin SuperSea Hawk MSK2, also a blend of  a 1/20th sized
      Mother Hawk
    , including HAP (an autopilot designed by RDL) to be operated:
    1. Independently, on any vessel with a HAP by an on board person, or Indirectly via:
    2. HAPs installed on vessels (to be operated by a land-based PATC, six-person team) which can be used to take off, land and/or pilot
    3. any experimental, or full sized  Gavin Hawk, including H23WACs. or
    4. one flock/6-person team (each flock of up-to-500 Gavin Hawks, carrying up-to-5k passengers), and/or
    5. XP Pro devices and/or including
    6. experimental or non-experimental Mother Hawks.
    Indirectly, by PATCO personnel,  via HAPs installed, which can be used to take off, land and/or pilot air, ground and sea based vehicles such as:
    1. Experimental Mother Hawks [eGSSH2.1] and/or
    2. up-to 8m Gavin Hawks  and/or
    3. up-to ~42 Mother Hawks and/or for
    4. taking off or landing vertically and/or
    5. along airstrips on land, sea, both or either.
    Operating flexibility: In addition, all XP versions of Gavin Hawks including but not limited to H23WACs, shall be planned, designed, built, tested and proven to be practical, economic and capable (in limited numbers) of landing and being stored on trains (and/or) other large, land, sea and/or air vehicles in motion and/or vertically landing on vehicles at rest (in open spaces) and/or traveling and/or in (open spaces) while (or not) being planned to travel through tunnels (under land and/or sea), or by air: then being re-fueled, un-stored and debarked and/or being taken off into the air for further flight(s).

    Before shutting down successful experimental work and trials of  GH, (including 1/10th sized Gavin Hawks and 1/20th sized
    Mother Hawks), the designs shall be scaled up (but not required for full sized H23WACs). In all other cases,  XP's products must be planned for initial expansion for manufacture, testing  and operation of full scale, full sized prototypes and volume production versions of GHs. This includes testing and/or re-testing of adequate samples of person-carrying capable Gavin Hawks and H23WACs, after scaling up to full size (or if not required) and building prototypes, to confirm successful operating flexibility as described above, with driver (operator and/or pilot) and/or passengers aboard, and/or neither or both. Testing of vertical takeoff and landing, nor carrying of drivers, passengers and/or cargo nor takeoff and landing on vehicles (except, possibly aircraft carriers) are not applicable to Mother Hawks.
    The basis of fuel cells, and their production and use in serial and parallel versions, makes possible mass production of cells and their use in very flexible applications, as required for power requirements. Their flexibility of fuel requirements for many different sources of energy make possible selection of fuel types based on availability and capacities for storage. This also assures almost unlimited range of powering 
    Gavin Hawks. The possibility of increased safety of switching sources of fuel in flight, is worth investigation, development, design and mass production.
