BACKGROUND OF THE INVENTION
The invention relates generally to flying Roads, specifically zero emissions electric vertical take-off and landing vehicles and 1) methods for engaging and disengaging the road vehicle from the air vehicle, 2) methods to carry the road vehicle and air vehicle combined system to cruise altitudes, 3) methods to house batteries, fuel cell systems and autonomous navigations and 4) systems integration the road module, air module, fuel systems and control systems.
Today's air mobility solutions mostly focus on just air travel and do not have the integrated ability to travel on road, thereby limiting markets for personal mobility, shared car, last mile cargo delivery and uninterrupted medical rescue and evacuations. They are also limited by the energy density of available battery chemistries. Past efforts in combined road and air vehicle inventions had:
- 1. Fully integrated design for air and road vehicle, which required added complexity for the wings to be folded or retracted into the vehicle, making the road vehicle bulkier and reducing reliability and endurance.
- 2. vehicles powered by gas turbines or hybrid gas turbines who are not zero GHG emissions
- 3. Vehicles which are not vertical take-off and landing types, requiring larger take-off and landing infrastructures, making them incompatible to urban travel.
The future of transportation depends on following factors:
- 1. Zero emissions propulsion (climate change)
- 2. Faster travel between cities and within cities (reduced time by 3 times)
- 3. Reduced urban and highway traffic congestion
- 4. Vertical Take Off and Landing (VTOL) to conserve space and infrastructure
- 5. Freedom of personal mobility by seamlessly traveling between cities and within cities.
- 6. Uninterrupted people transportation in personal, fleet, military, Cargo delivery and rescue missions.
BRIEF SUMMARY OF THE INVENTION
The modular autonomous air and road mobility (AARM) vehicle with Vertical Take-off and Landing (VTOL) capability provides combined air and road mobility solution.
AARM is clean energy powered, modular vehicle, which can be undocked and redocked into road module and air module, providing uninterrupted autonomous mobility between air and road. In addition, the modular design enables:
- Easy navigation through highly populated areas without the need to accommodate fixed wing aircraft on urban roads.
- Reduced energy consumption and noise levels in urban roads by not having to carry the air propulsion system into urban areas.
The road and air modules dock with each other through a sensor guided docking and load carrying mechanism (SGDMS), allowing connectivity, command and control. The vehicle can be scaled appropriately to serve markets in personal mobility, shared car, air taxis, regional air transport, cargo and shipping, defense missions, medical evacuations and air ambulances. In addition to modular design and longer cruise distance, the invention is aimed to and disrupt the nascent electric air mobility industry through using a) emerging technologies in light weight fuel cells for aviation, b) high energy density batteries and c) level 4/5 automation

DETAILED DESCRIPTION OF THE INVENTION
AARM Autonomous Air and Road Mobility vehicle, which is H2 fuel cell and battery powered. It is modular in design and can be disengaged into Road module and air module, providing seamless and uninterrupted autonomous personal mobility between air and road. In addition, the modular design enables:
- Reduced congestion and easy navigation through highly populated areas without the need carry the fixed wing aircraft on urban roads.
- Reduced energy consumption and noise levels by not having to carry the air propulsion system into urban areas.
The Road module and air module dock with each other through a unique sensor guided docking and load carrying mechanism, allowing connectivity, command and control.
The vehicle and all its components and subcomponents are scalable according to the payload size, gross vehicle weight, cruise distance, cruise altitude, cruise speed, VTOL height and Road mileage requirements.

AARM vehicle consists of:
Air Module (105) II) Road Module (110) III) Sensor guided autonomous docking and mounting system (SGADM) (135) and IV) Autonomous Navigation, Communications, Command and Control System (ANC3)
Each of subsystems, their key components and suggested manufacturing are listed below:
I) Air Module (105):
Functions of Air Module (105) are to:
- a. vertically take off and land (VTOL) the whole vehicle with its payload into the air, with a vertical climb up to 1000 feet.
- b. House h2 fuel cell and storage units or battery systems storage (the power modules 115), whichever is selected to achieved to meet propulsion requirements in terms of vehicle weight and cruise distance.
- c. Provide scalable design on propeller blades, packaging spade for fuel cell
