Advanced Multi-passenger VTOL Aircraft - AMVA

  2. 2. The necessity of VTOL aircraft Micor Technologies A feasibility study shows there is a need for a multi-purpose General Aviation aircraft with the ability to take-off and land vertically. In particular, the Emergency Services would benefit tremendously from the ability to help patients, including deployed military personnel, at otherwise inaccessible locations, thus improving their mission and helping to save lives. At the same time, every day, millions of hours are wasted worldwide on the road. The Vertical Take-off and Landing aircrafts (VTOL) have the potential to radically improve urban and interurban mobility, giving people back the time lost in their daily commutes. Furthermore, VTOLs do not need to follow fixed routes and can chose the shorter transportation path. This new class of vehicles is emerging in the midst of an already dramatic transformation in the way people and goods move around. Driven by a series of technological and social trends the future of mobility could ultimately create a more integrated transportation system that is faster, cost effective, cleaner and safer than today’s. The state-of-the-art VTOL technology in use today is the helicopter, but they are noisy, inefficient, emitting a high level of pollutants and incurring high costs for mass-scale use. VTOL aircraft will make use of electric propulsion so they will have a vert reduced operational emissions and will likely be quiet enough to operate in cities without disturbing the neighborhoods. Within this boundary conditions we tried to develop a "best in class," advanced personal VTOL aircraft system utilizing the new Distributed Electric Propulsion - DEP, combining the VTOL capabilities of a helicopter with the horizontal speed and payload capability of a traditional airplane. This new Advanced Multi-passenger VTOL Aircraft, for short AMVA, uses a new DEP propulsion system and will provide an accessible and affordable transportation platform from door to door for both civilian and military applications while reducing capital and operating expenses. 5/18/2020 2

  6. 6. AMVA concept -The flight physics in vertical direction Micor Technologies The new propulsion system uses a thrust augmenter configuration associated with non-verticality of the slip stream to increase the lift in static conditions. VTOL configuration total lift is the result of lift created by the wings added to the thrust created by the propeller. In static conditions and at slow speed, the lift capacity increases as a result of higher circulation around the wings, improving the thrust/weight ratio characteristic of the aircraft. For the double biplane wing configuration, the weight is balanced by the sum of the thrust produced by the propeller and the lift produced by the wings. Because each front wing of each thrust unit is placed in the inlet region of the propeller it will develop a certain amount of lift due to the pressure difference between the wings’ lower and upper surfaces. On the lower surface, the pressure will be equal to the atmospheric pressure, while on the upper surface, the pressure will be slightly lower. As in the case of the front wing, because each rear wing of each thrust unit is placed in the outlet region of the propeller it will develop a certain amount of lift as well due to the increased pressure exercised on the lower surface of the rear wing. 5/18/2020 6

  18. 18. Hover efficiency as a function of disc loading Micor Technologies 5/18/2020 18 The traditional way of determining vertical flight and hovering efficiency is to consider the power loading of the vehicle. This is a simple ratio between the weight of the vehicle and the power of installed engines. A more efficient vehicle requires less powerful engine to hover at a given weight. Another method of measuring hover efficiency is disc loading, i.e., (Weight of vehicle) / (Area of thrust producing structure). A VTOL aircraft with high power loading and low disc loading is the most efficient at hovering , as is the case for AMVA.
