Product description

THE MARKET OPPORTUNITY
Copters are inefficient, they are "Fuel Hogs!" (copters include helicopters, quadcopters, tricopters...).
Fixed wing aricraft require runways.

THE SOLUTION
The passively-controlled tiltwing techology is light weight, cheap, and robust method where impacting air from forward movement vectors the front propellers more-forward in transition to fixed-wing flight (patent pending).

Terretrans breakthroughs in lifting body technology (patent pending) are important for optimal performance.

VIDEOS AND IN-ACTION
See HS-Drone.com for the latest breakthroughs and videos of performance.

The transition from hover includes:
1. pitching entire vehicle forward to initiate forward velocity.
2. impacting are vectors the forward tiltwing to provide a greater forward thrust component versus vertical lift.
3. propellor rotational speeds are controlled to keep a favorable vehicle pitch of 1 to 10 degrees.
4. greater forward velocities both increase lift from the fuselage/wings and vectors tiltwing more forward.

THINK ABOUT IT
Scalable, Simple, Light Weight, Robust
None of today's busses, trains, or aircraft could compete with a copter that has the speed and fuel efficiency (per payload) of fixed with aircraft. It is now possible, and the commercial path starts with toys where techology can be scaled to large parcel and passenger markets in the 20-1000 mile range.

BENCHMARK TECHNOLOGIES
Fuel efficiency is roughly proportional to left-to-drag (L:D) ratios. Here are some benchmark L:D:
0.8:1 Estimate of cruising quadcopter efficiency (prop air pushes down on upper fuselage surface).
0.9:1 Hovering copter.
1:4 Best of cruising helicopters.
1:4.5 V-22 Osprey when cruising.
18:1 Efficient passenger jet.
27:1 Future aircraft (like HS-Drone, and Terretrans) where fuselage is optimized as lifting body.
