JetQuad: VTOL Jet-Drone

Compact Form-Factor

The JetQuad is a quad jet-engine powered drone fueled by ordinary Diesel fuel. Each turbine generates 25HP of raw jet-power for a combined power output of 100HP. That is a significant amount of power considering the fact the drone is just under 2-feet in diameter and is about 2-feet tall. This means that the drone can carry more and go faster then any drone of similar size.


Rocket-Grade Power

The JetQuad operates  much like a standard multicopter drone with vertical take-off/landing and automated flight through pre-set way-points. However, the original concept of the JetQuad was a booster stage to lift rocket stages above the atmosphere with return to launch-pad capability. So although JetQuad is a drone, it has the power and flight capabilities of a rocket.

JetQuad Testing

Testing a drone like the JetQuad requires patience and countless hours of tests. We have constructed a custom-designed test-cell where we tether the JetQuad and test the stability at lift-off which is the most complicated portion of a typical JetQuad flight.


Control System Development

It is no easy task to develop a fully functional control system for a jet-engine powered drone. For this reason, we have constructed an electrical drone called FanQuad. It is identical to the JetQuad with the exception that the jet-engines are replaced with EDF (Electric Ducted Fans). Check out the FanQuad test video on the right.

 How does the JetQuad outperform conventional electrical drones?

To answer this question, one must get familiarized with two physical concepts - Energy Density and Power Output. Thanks to the use of Diesel, as opposed to Lithium-based batteries, JetQuad has both higher Energy Density and Power Output when compared to a Multicopter of similar size.

Energy Density

The energy density is measure of how much Energy is stored in a unit mass and is measured in MJ/kg. Liquid Diesel fuel which powers the JetQuad has Energy density of 40MJ/kg while the solid Lithium-based battery which powers Electrical drones has at most, an energy density of 1MJ/kg. This means that for the same on-board mass of fuel storage, the JetQuad stores 40 times more energy then the equivalent electrical Drone. Of course, the increase in mass of the Jet-Engines themselves offsets this relationship, however, not significantly. The US Department of Energy has recently initiated a 5-year research to develop the next-generation battery with a target of 3MJ/kg energy density - still 1/10 of the energy-density of Diesel. So clearly, the JetQuad will remain competitive for many years to come.

Power Output

The power output is a measure of how fast one can utilize the stored on-board energy and it is measured in Watts. We know that electrical drones are greatly limited in power consumption due to the maximum discharge rate of the battery, the operating amperage of the Electronic Speed Controllers and the maximum current on the Brushless motors. The current has to be limited in order to prevent overheating of any of these electronics. On the other hand, a jet-engine is supplied with diesel fuel by means of an electrical fuel pump. The fuel pump as well as the combustion chamber can readily accommodate very high fuel flow rates and generate large amounts of power. The relaxed power output limitations on the jet-engine allow the designers to squeeze much more power out of the same volume when compared to an electrical motor of similar size.

JetQuad: Changing the Game of Drones Forever!

The Drone Market is hot and fast evolving. FusionFlight would like to be on the forefront of this market, and once the appropriate regulations are in place, supply the fastest and most powerful jet-engine powered drones to a variety of clients. With its incredible range and payload capacity, the JetQuad drone has the potential to dominate Package Delivery, Military Surveillance, and Fast Medical Response Markets, just to name a few.
