Ground Breaking Aerospace Technology

WHAT WE DO

We are developing a breakthrough aerospace technology platform that will overcome the speed and scalability limitations of the helicopter while at the same time reinforcing (enhancing) the VTOL (vertical take-off and landing) potential of the airplane.

OUR TECHNOLOGY

DRAC uses a ducted rotor system, powered from the tips, to achieve vertical lift. The torque required to turn a rotor system is proportional to the moment arm. By placing the propulsion means at the rotor tips we increase the moment arm significantly reducing the force required to turn the rotor by a very large magnitude. The moment arm of a helicopter can range from 1.5 inches to 2 ft.

 

That of the DRAC will be governed by the overall dimensions of the vehicle meaning it will be larger than 10 ft. The effect of this is to significantly reduce the power required. Preliminary analysis through the momentum equation shows power reduction of 40%-60% compared to current fielded VTOL technologies and competes favorably with conventional airplane.

 

Current aircraft use as much as 25% of their onboard fuel for take-off. The DRAC concept will reduce this by margins close to 60% reducing operating expenses and pollution effects.

There is a strong need in both the civil and military aviation space for a technology platform, and an aircraft, that can take-off as a helicopter, carry as much payload as an airplane and fly just as fast beyond the range of typical helicopters.

Our technology will allow development of aerospace capabilities that will:

  • Mitigate airport congestion by reducing runway and taxing requirements and open up more remote locations to high passenger and cargo capacity flights

  • Enhance military operational readiness and efficiency by affording delivery of higher payloads to greater distances at faster speeds.

  • Provide emergency services, executive transport and general aviation communities with a more versatile, roomy, efficient and quieter aircraft.

  • Give drone developers and operators more under-belly space for instrumentation and sensing technology.

Our technology is a platform from which derivative aerospace products can be developed ranging from drones and emergency evacuation vehicles to airliners and space flight systems.  

HOW WE'RE DIFFERENT

SCALABLE - VERSATILE - FAST - EFFICIENT

VTOL and Speed

The DRAC can take-off and land vertically much like a helicopter eliminating need for a runway unlike conventional airplane.

 

It also posses the ability to fly at higher forward speeds than a helicopter and comparable to those of an airplane. Preliminary analysis point to forward speeds exceeding Mach 0.8 and advance ratios greater than 5.

Lower Power

The DRAC power requirements are significantly lower compare to that of the helicopter which will translate into lower fuel required and lower operating costs. The DRAC achieves this through: Elimination of conventional transmission and gearbox which reduces transmission system weights, noise and power requirements. Mounting engines on the ducting increases moment arm requiring a lesser turning force to achieve a given rpm of the rotor (Torque = Force x Distance). Both of these advantages will also result in smoother quieter rides.

Multi-Role Applications

Concepts derivatives will be optimized for a wide range of applications affording it a multi-role application. These roles are both in civil and military environments in both manned and un-manned formats. They will include civil passenger transport, civil cargo transport, executive transport, policing, search & rescue, military transport, drones, and space flight systems.

Scalability

With a high degree of scalability, the derivatives will have a wide range of payloads from as low as 400lbs civil trainer (200kgs) to as high as 450,000 lbs airliner (230,000 kgs). This is an advantage not possessed by the conventional helicopter and when combined with VTOL, not possessed by conventional airplane. It can also be developed as a drone of 10lbs (5kgs) for the security and civil markets.

Maneuverability

The DRAC will have a high degree of maneuverability compared to both helicopters and airplanes.

The helicopter fuselage is suspended from the main rotor by the rotating shaft like a pendulum.  In any maneuver, therefore (including axial, forward and directional flights), fuselage lags the rotor by a given order of time magnitude depending on rotor & helicopter dynamics and coupling. This lag will have a far much lower value for the proposed concept design as a result of the disc and rotor being on the same plane and coupled circumferentially (analogous to wing/fuselage coupling). It's VTOL ability enhances maneuverability over the airplane.
