1. Technology Outline
BENAVIS schematic drawing
demonstrating enclosed
(bladeless) rotor system.
Makes flight in bad weather conditions
possible compared to conventional helicopter
travel
Exceptional flight stability
Vertical take-off/landing
Less energy consumption (greener)
Much lower direct operating cost
compared to helicopters

2. Applications & Markets
• Passenger and Goods/Merchandise Transport
• Civilian services (Emergency, Search & Rescue etc.)
• Recreational Activities (Leisure, Hospitality, Toys)
• Non-Civilian Applications
• UAV applications

3. Foreseen Characteristics
• Cruise Speed: 200/300 Km
• Range: 1000/200 Km
• Consumption (2 seater model): 9.2 liters/100 Km
(calculations conducted using ROTAX system)
• Current Production Capacity: 100 units (2 seaters) /
month
• Direct Operating Cost: much lower than helicopter

4. a. Innovation / b. Advantages / c. IP
 It is well known that helicopters with enclosed rotor
systems are far more efficient than open rotor
systems , but in general with limited scale-up potential.
 BENAVIS has developed an enclosed (bladeless) rotor
system that has vastly improved the scale-up issue.
 As a result, our system makes a new greener and
secure helicopter rotor system possible.

b. Advantages
• Enclosed rotor systems are more efficient (greener) and
offer better operational security as the rotors are fully
protected.
• The innovation facilitates scale-up
• In the event of an accident – the enclosed (bladeless) rotor
system allows for use of parachutes, airbags or floating-
bags to assure safer landing potential
• As enclosed rotors are more efficient, overall dimensions
are smaller than conventional rotor systems.

c. IP / Conceptual Benefits
• Conceptual analysis (tests) requires a small budget
• This technology offers considerable scale-up potential
compared to other enclosed rotor systems
• Production costs forecast to be low compared to traditional
construction costs in this field
• A multitude of applications possible where open rotor
system technology is not feasible
• These characteristics open up potentially huge markets

c. IP / Conceptual Risk Factors
• At this point, the enormous potential of this
concept means we are obliged to follow a strict,
discrete communication/marketing plan to protect
this concept, which comprises:
Proof of Concept (theory already validated by
experts, proof of which can be supplied under
appropriate confidentiality agreements)
Securing of patents and construction of first
prototype and certification

6. Regulatory Bodies/Certification
• At time of writing, certification requirements for
this technology relate solely to helicopter norms.
Planned additional applications foresee other
norms relating to aircraft regulations.
• First step is “light helicopter certification”. This
substantially decreases funding requirements and
benefits from huge potential worldwide market.

7. Identified Competitors
• No comparative technology has been patented to date
• The rotorcraft technology field is gaining increased
interest and is the subject of major research
investment from NASA – 40 Million USD – see next
slide
• Our technology represents a new vehicle that will rival
helicopter travel, thus, we consider our technology, at
this point, to rival the NASA research programme ,
which began on the 25th February 2009.

NASA Awards Rotorcraft Technology Development Contract
WASHINGTON -- NASA has selected three companies to receive a subsonic rotary wing technology development
contract valued at $40 million. The companies sharing the award are Bell Helicopter Textron Inc. of Hurst, Texas;
The Boeing Company of Chicago; and Sikorsky Aircraft Corp. of Stratford, Conn.
This is a cost plus fixed fee, indefinite delivery, indefinite quantity contract with a five-year period of performance
beginning Feb. 25, 2009.
The work will be performed for NASA's Subsonic Rotary Wing Project, which the Fundamental Aeronautics Program
of NASA's Aeronautics Research Mission Directorate in Washington funds and manages.
Under the terms of the contract, the three companies will compete on task orders to provide research and
development support. The support areas include advanced rotorcraft technologies, rotorcraft requirements in the
Next Generation Air Traffic Management System, prognostics and health management, advanced rotorcraft
configurations, research flight testing, wind tunnel test stands, hardware gear testing components, rotorcraft drive
system sensitivity studies, avionic processor equipment and Global Positioning System upgrades, engineering
analyses of advanced concepts, subject matter expert review, and advanced cockpit and crew station research.
The work will be performed at Bell's facility in Hurst, Boeing's facility in Mesa, Ariz., and Sikorsky's facility in
Stratford.
