deltaBurn applies novel, Elegant Aerodynamics to propellers, rotors and turbofan blades. We achieve extraordinary, double-digit changes to propulsive efficiency by significantly altering flow around any actuating blade.

When we do what we do, the thermodynamics of the engine core are not altered; we only change the efficiency of the propulsion disk. Our on-blade modifications eliminate regular shocks on the a blade, both recovering that lost energy and pushing sonic flow over the entire blade. We also change post-blade swirl, and more. Much more.

Those with the relevant background will instantly realize two things:
“That’s Not Possible” and
“Wow, this will affect everything!“

Indeed, some of what has been learned in propulsive aerodynamics during decades past, and deemed immutable, needs a serious reboot. Once our patents are public, we’ll work on that.

For perspective: our activity largely restores the lost fan disc thrust that normally decayes from the moment a take-off roll starts. By the time the cruise phase is reached a normal fan will have lost most of its thrust, while a deltaBurn-modified fan is delta-Veeing away nicely. Some 50% more, actually.
Let that sink in.

During test flying, we’ve sees one-third fuel burn reductions caused by torque reduction; less power input required to turn the fan. Any deltaBurn-modified aircraft will cruise with less N1/N2 than before. Much lower EGT, core temperatures, stresses and vibration too. Permanently derated.

Who is this for? Any operator interested in lowering fuel burn and emissions,  and having a lot more range: airlines, business, GA, military,  anyone.

We aim to help reduce global aviation emissions by a significant, step-changing amount, and in doing so support SAF adoption. A significantly reduced global fuel volume requirement. And to maximize our reach, we’ll offer low-threshold adoption through licensing our STCs to interested users. Decarbonization as a Service.

When can we have this? As soon as your specific Supplemental Type Certificates (STC) has been completed by us and is available to the market.
We’ve started work with the FAA on our initial STC with our SA226/TPE331 Merlin turboprop, which is well under way. We’re also working with a few operators to start with the BAe146/LF507 and CRJ-200/CF34-3 platforms.

What proof do you have of your claims? Plenty. The video clip below shows a high-speed ground run with our TFE731-powered 1124A Westwind flight test aircraft, left engine modified. This particular test happened a few years back (time flies without proper funding for expensive certification programs!).
Do pay particular attention to the engine stack. The numbers are impressive.

More videos showing different aircraft and engine types are available, most famously the one of a 737/CFM56-3, which we show in our keynotes as well.
