THE FUTURE OF TRANSPORTATION
A SOLUTION TO THE WORLD'S ENERGY PROBLEMS AND GLOBAL AIR POLLUTION
The Verticraft ( US patent 8,505,846) is a VTOL ( vertical takeoff and landing) aircraft that makes all previous designs obsolete. It can be scaled from small package delivery drones to full sized manned aircraft using hybrid electric motors powered by batteries or hydrogen. The small radio controlled version will make the current drone platform obsolete. The drones use 4,6, or 8 propellers and motors that fly sideways through the air very inefficiently. The Verticraft uses 2 props and motors with pivot wings to take off and land and hover, then fly horizontally using the wings for lift making it 8 to 16 times more efficient than the current drone platform. Mass produced the larger manned version would make cars obsolete eliminating all air pollution and energy problems as well as global gridlock of ground travel caused by population growth.
Hydrogen is the optimum fuel for the Verticraft. A two thousand mile array of solar panels
on the Mexican border would generate enough hydrogen to supply the total energy requirements of the USA and solve the border security problem.
Everyone knows that the automobile will eventually become obsolete, the only question is when. The certainty of global gridlock as the world population increases will accelerate the obsolescence of the automobile." China's traffic jam, which has lasted a full 10 DAYS and is expected to last WEEKS, is being blamed on highway roadwork, compounded by minor accidents and a few breakdowns. "Peter Ford, Staff writer / August 24, 2010
China's traffic jam: Trucks jam up on the National Highway 207 in Wanquan county in north China's Hebei province Monday.
Shanghai imposes a $ 14, 530 car license fee to discourage driving in the city.
Take a city like Paris – in a nutshell:
Cars spend most of the time just parked: more than 95% of their service lives
50% of users drive less than 4.5 miles a day; 80% travel less than 30 miles a day
The average speed of a car trip within Paris is 6.25 mph.
"Less than half of 1% of the land area in the United States is covered by roads of all kinds, not including rights-of-way, parking lots, and driveways."
Which means that 100% of our ground travel is confined to 0.5% of available land area . It is no wonder that more than 30,000 people in the U.S. alone and a million people word wide die from ground traffic collisions. Over the twentieth century, the number of automobiles in the U.S. has grown from practically none (about 1900) to one per household (about 1950) to more than one per licensed driver (2000). Growth in the number of motor vehicles just can't keep going up because there is nowhere for it to go.
The proposed automated air travel system would allow 100% of the travel over 100% of the land area multiplied by many flight levels generating nearly an infinite number of flight trajectories reducing the probability of a collision to be near zero.
The current system has cars on intersecting roads at the same altitude. The industry is moving toward autonomous cars to minimize the probability of collision. which will evolve into one giant automated parking lot caused by the eventual increase in the number of ground transportation vehicles. The freeway system using over and underpasses minimizes the intersecting road problem but it is impractical to build a freeway for each individual vehicle to each destination. Their is no central ground traffic control computer system. The Verticraft's destination would be entered into the FAA's air traffic computer system which will generate a virtual freeway similar to Google maps with altitude to each vehicle using a near infinite number of non intersecting flight paths with 500 ft vertical, lateral, and horizontal separation to make the probability of collision near zero.
The ultimate transportation vehicle is the Verticraft. ( US PATENT 8,505,846)
The Verticraft is a vertical takeoff and landing aircraft ( US patented) that can fly nearly as fast as a private jet but takeoff and land like a helicopter.
The 6 passenger commuter version with two 400 kw motors will be plugin electric 85kwh battery powered for the 32 mile average distance traveled. The 16 mile trip at 240 mph or 4 mi/min will be recharged by residential or business solar panels which will make zero operating cost, plug in recharge facilities or use 1 min quick change battery packs. Maximum range at 345 mph is 84 miles. In a 32 mile diameter dome 15000 ft in height, three million Verticraft can fly every four minutes with 500 ft separation of the vehicles. The hybrid electric/hydogen
eight passenger version has a range of 576 to 3000 miles depending on the engine selected.
The following video shows the Convair XFY-1 ( Pogo ) military version flown in 1955 that used now obsolete components and flight control systems that made it difficult to land.
A patent pending version will maintain the fuselage in the horizontal position without the need to pivot the seats.
The public has been flying on aircraft making automatic landings for more than 30 years. The FAA requires that aircraft make automated landings when the weather is at the lowest possible visibility allowed for landings. No aircraft accidents or fatalities have ever been attributed to automated aircraft landing in the history of aviation. The Asian airlines accident at SFO would have been prevented if the aircraft had made an automated landing.
The Free-Wing Concept described in the patent establishes the Verticraft as the safest aircraft ever designed because it cannot be stalled.
A free wing is an aerodynamic lifting surface which is completely free
to rotate about a spanwise axis, subject only to aerodynamic pitching moments
and unrestricted by mechanical constraints. To provide static angle of attack
stability, the axis of rotation is located forward of the aerodynamic center of
the wing panel.
Figure 1 is an illustration of a free-wing configuration in which the
equilibrium angle of attack is e
stablished through a balance of moments created
by a trailing-edge control surface and the torques produced by the lift and drag
With suitable mechanical limitation on control surface displacement the wing cannot be forced into the stall regime. Furthermore, the anti-stall behavior is not influenced by center of gravity variations in the fuselage assembly.

FIGURE 1. CROSS-SECTIONAL ILLUSTRATION OF THE FREE WING
An additional major benefit of the free-wing concept is substantial
alleviation of the normal load factor response to vertical gusts. The gust
alleviation arises from the tendency of a stable lifting surface to maintain
a prescribed lift coefficient by responding to the natural pitching moments
which accompany changes in flow direction. While all stable aircraft tend to
relieve the lift increment due to a vertical gust by pitching into the relative
wind, the rapidity of the alleviating motion depends upon the pitching moment
of inertia. Because of the greatly reduced inertia of the wing panel, compared
to the aircraft as a whole, the free-wing concept provides a significant reduction
in the turbulence response.
The following video shows the autopilot capabilities.
The Verticraft can also have a ballistic recovery parachute system for emergency landing if desired. The Verticraft will have a medical emergency button that will take the vehicle to the nearest hospital at 360 mph or 6 miles per minute in case for example one thinks they are having a heart attack and needs immediate medical attention. This would drastically reduce the emergency medical response time which would normally require a 911 call for a ground ambulance to drive to you and then to the hospital.
The automated flight system is equivalent to a ground transportation system where each vehicle has its own separate road to its destination assuring zero probability of collision. Travel by Verticraft eliminates the needs for roads, bridges, destruction of the environment, foreign energy sources and eliminates the air pollution and possibly the global warming caused by the current transportation system.
The Verticraft makes high speed rail obsolete as described below. Traveling at high speed on or near the ground is extremely dangerous. An airliner is perfectly safe at high speed at high altitude but becomes much less safe at ground level because of the relative high speed needed for takeoff and landing. The Verticraft lands at zero forward speed at ground contact. The Verticraft eliminates the need to congregate large groups of people for transportation by air or rail which minimizes threats from terrorists or any other mentally unstable individuals.
VERTICRAFT LOS ANGELES-SAN FRANCISCO 345 miles in one hour between Vertiports ( heliports )

1152 passengers per hour for 12 hours per day= 13,824 passengers per day= 5,045,760 passengers
per year between 36 Vertiports
144 Verticraft @ $500,000 each= $72.2 million
pilot cost = $14.4 mill per year
natural gas fuel= $120/hrX 144 Verticraftx12hr/dayx365 days/yr= $75.688 mill/yr
Verticraft other operating costs=$ 14 mil per year
Total opertaing costs= $104.088 mill per year
$100 per passenger round trip= $500 million gross -$108 operating cost = $392 million profit per year
Many more jobs in the transportation industry would be created as the Verticraft begins to replace the current aircraft and ground transportation vehicles. Mass transit in high density cities would be greatly enhanced by the elimination of autos and trucks and their associated traffic jams as well as the related infrastructure of traffic lights, etc. http://www.skytran.net/
Current personal vehicles are parked 96% of the day. The optimum solution for daily transportation would be for all of the manufacturers use an on demand travel system like Uber.
The Verticraft would pick up the passenger and transport them to their destination, then fly to transport other passengers as they are scheduled for the next trip. No one would need to own a vehicle for personal daily transportation. Only business vehicles that would be required to carry
equipment necessary for the business would need to own a Verticraft. All non-business personal travel can be with the on demand system. The daily cost of personal transportation would be greatly reduced by the on demand system by eliminating the costs of owning and maintaining a personal vehicle.
