Welcome to deltaBurn!

“Your work could well be the greatest change in propulsion efficiency in the history of atmospheric flight. *

Through the application of an elegant, aerodynamic alteration to the flow around propellers, rotors and turbofan blades, deltaBurn achieves extraordinary changes to propulsive efficiency. Large Double-Digit changes.

When we do what we do, the thermodynamics of the engine core are not altered; we only change the efficiency of the propulsion disk. And what is it that we do? Our on-blade modification eliminates the regular shock on the fan blade; recovers that lost energy; pushes sonic flow over the entire blade; changes post-blade swirl; and more. Much more.

Those with the relevant background will instantly see two things: that this is deemed impossible and how this affects everything. Indeed, some of what was learned in decades past needs a serious reboot.

To put some perspective on just how large a change this is: our activity restores fan disc thrust at speed and altitude. A normal fan will have lost just about all of its thrust by the time it enters the cruise phase, while a deltaBurn-modified fan is delta-Veeing away nicely at altitude. 50+% more nicely, actually. Let that sink in.

The mentioned one-third fuel burn reduction simply comes from torque reduction, less power required; a deltaBurn-modified aircraft will now cruise with a lot less N1 than before.

Who is this for?
Everybody- Airlines, Business/GA, GA, military. Our aim is to help reduce global aviation emissions by a significant, step-changing amount, and to support SAF adoption by significantly reducing global requirements. To maximize our reach, we’ll ensure low-threshold adoption by licensing our STCs to interested users. Decarbonization as a Service.

When can we have this?
We’ve started the processes of bringing this technology to market in the form of Supplemental Type Certificates (STC) for airlines and operators of both turbofan-powered or propeller-powered aircraft.
Our initial STC will be for the SA226/TPE331 Merlin turboprop, which is well under way. In addition, we’re ramping up for the BAe146/LF507 platform.
Our STC programs are live with FAA.

What proof do you have of your claims?
The video clip below shows one of our high-speed ground runs with the left engine of our TFE731 powered 1124A Westwind flight test aircraft modified. This particular test happened a few years back (time flies without proper funding for the expensive certification program).
More videos with different aircraft types, different engine types is available.

Pay particular attention to the engine stack. The numbers are impressive:
