The core of Skyworks’ Gyroplane and Gyrodyne technology is Skyworks’
unparalleled understanding of Sustained Autorotative Flight. Autorotation is
the ability of a free-spinning rotor-wing to generate lift.

For a Gyroplane in forward flight the unpowered rotor creates lift
through autorotation, with forward thrust provided by an engine-driven
propeller(s) or by jet engine(s).

VTOL: The ability of an aircraft to take off and land without a runway.

Skyworks’ combination of Sustained Autorotative Flight with
VTOL will Disrupt Today’s Markets.

VTOL: If Airplanes didn’t need Runways…
Pilots and passengers would be safer
Emerging Countries wouldn’t be stymied by expensive infrastructure requirements
Airports could be located in City Centers (to be called “Vertiports)
A farmer’s field could be a regional distribution hub
An aviation economy could spring up overnight
Modern Airports could eliminate runway congestion
Commuter Airliners could use “Landing Pads” next to their gates
Landing slots could be allocated only to long-distance flights
Airports could have more flights, passengers, and revenue every day
“Too Short” Airports could be cargo and passenger hubs located closer to markets
and become an integral part of our economy
Emergency Supplies could be delivered next to the Need instead of to the nearest
functioning airport

Sustained Autorotative flight: If Helicopters weren’t so complex,
expensive, and difficult to fly…
Pilots and passengers would be safer
Owners would pay less to buy, maintain, and operate them
Law Enforcement agencies would be able to use fewer of them to do the same job
Air transport companies could run scheduled flights based on their reliability
Helicopters, if changed to “sustained autorotative flight” aircraft, could be made to fly
faster, farther, and with a higher payload
People would find more ways to use them

VTOL Sustained Autorotative flight AND Hovering: If the Military Had
them…
Pilots and passengers would be safer
The U.S. Army’s “Future Vertical Lift” concept would be closer to reality:
create a new rotorcraft that uses new technology, materials, and designs that are
quicker, have further range, better payload, are more reliable, easier to maintain
and operate, have lower operating costs, and can reduce logistical footprints.

SAFETY
Properly designed, Sustained Autorotative Flight Aircraft
are the SAFEST FORM OF POWERED FLIGHT ever copied
from Mother Nature.
A Rotor in Autorotation is an Aerodynamic Parachute
Engine Failure: Gyroplanes descend right side up and
controllable to a normal vertical landing with a glide path about
3 times that of a helicopter
Stalls: Gyroplanes Never Stall – if flown too slowly, they
simply lose altitude right side up and controllable
Stability: Gyroplanes are “Hands off stable” like airplanes
Runways: Not needed, gyroplanes can land wherever they fit
Airplanes:
Stall and Fall if flown too slowly, the leading cause of
accidents, happening during takeoff and landing
Runways are required for safe landings

SAFETY
Nature’s Choice
Helicopters: Shaft-Driven rotor Technology
Creates torque and complexity which reduces safety:
More parts: increases risk of mechanical failure
Higher Levels of Maintenance: increases risk of error
Torque: harder to fly increases pilot error and mechanical
stress
Requires a direct connection between rotor and engine:
Engine Failure: requires highly skilled, immediate, practiced action from the pilot to
achieve Autorotation - (where gyroplanes begin)
Uses a rotor design not maximized for autorotation:
Glide path: significantly shorter than gyroplane
Higher Rate of descent: less time for helicopter pilot to make emergency decisions
Helicopter technology is more efficient at hovering, but hovering is
not necessary to move people and cargo between locations.

Design Simplicity – Much less complicated than helicopters
Reliability – Far fewer moving parts means fewer problems
Mission Readiness – Far less maintenance required to remain airworthy,
so nearly always available
Profitability – The pocketbook benefits of simplicity:
Lower Acquisition,
Maintenance, and
Operational costs
Combined = Much Higher Profitability

GyroLiners: Airplanes that don’t need a Runway
Only the rotor system - rotor blades, head, and controls – is shared with Helicopters.
In all other respects - wings, tail, ailerons, elevator, rudders, and main engines used
for forward thrust (propellers or turbofan), GyroLiners are an airplane.
VTOL is provided through prerotation of the rotor using compressed air tip jets.

The Heliplane is a Gyroplane that can Hover
Hovering requires more power than the “jump takeoffs” used for VTOL
Skyworks Gyroplanes can achieve VTOL with about 10-20% of Hovering power
The Hawk series use a mechanical gearing system to spin the shaft while on
the ground but never in the air
GyroLiners use compressed air tip jets for prerotation – tip jets can be used to
improve flight characteristics because no torque is generated
Addition of fuel-powered tip jets allows the Heliplane to emulate the hovering ability of
Helicopters while maintaining the natural advantages of Gyroplanes – safety, speed,
simplicity, range, cost
Helicopters designed to overcome the Torque Handicap are extremely
complex and costly

A White Paper by Dr. Daniel P. Schrage, Dir. Of Vertical Lift Research
Center of Excellence at Georgia Tech, June 2015:
“ Sustained autorotative flight uses autorotation throughout its flight envelope, which
gives several advantages over powered rotor flight.”
“…[Skyworks] has been aggressively patenting reaction drive rotor system and related
technologies over the past several years. This should be attractive to a risk sharing
partner as many patents have been issued over the last two years.”
“The Heliplane Gyrodyne Demonstrator Aircraft (HGDA) goals combined vertical
takeoff capability with a maximum speed of 400 mph (347 kts) at 20-30,000 ft altitude.”

flow directly into the cost of doing
business.
Payload efficiency - lower non-

Simplicity – fewer moving parts
Easier to operate – lower pilot cost
Safety – lower insurance premiums
Cheaper to buy – less depreciation
Estimates assume the same number
of hours for each aircraft

readiness also favor gyroplanes
