Technology Primer
Our Philosophy: Radical Thinking. Practical Application.
Our founder began with a simple challenge: what if the “absolute” aerodynamic limitations of propulsion were not absolute after all? By stepping outside conventional assumptions, deltaBurn turned a century-old problem into an elegant solution.
Propulsion Aerodynamics Redefined.
For 150 years, aviation has accepted propulsion inefficiencies as unavoidable, and now deltaBurn overturns that belief. We apply practical aerodynamic solutions to problems once considered absolute, and in doing so unlock performance and efficiency gains for turboprops, helicopters, and turbofan engines alike.
The result is simple: the same expected thrust at some one-third lower fuel flow, with lower engine stresses, temperatures, and a cleaner environmental footprint — all from an easy, rapid retrofit.
Our Approach: Simple Physics. Profound Results.
We all know that lift and drag are constantly managed on wings and tail of an aircraft, and deltaBurn applies the same principle to propellers and fan disks. By reshaping blade aerodynamics in ways that traditional turbomachinery design systems cannot, we neatly step around the limits that seem to be baked into conventional software and design practices.
We don’t make any alteration to the core of the engine. Power can come from a rubber band, a set of pistons, a turbine — we are agnostic to the input. Our modifications reduce the amount of power (torque) required to produce a given thrust from an aerodynamic propulsion disk. This lower shaft power means lower fuel burn, lower EGT/ITT, and longer engine life.
None of this is a theoretical concept. It’s been flight-tested, lab-verified, and is 100% repeatable.
Why Does This Matter? Well, engines perform worst when aircraft perform best.
Conventional propellers and (turbo)fans push peak performance at zero forward speed. The very moment when brakes are released, disk efficiency declines as altitude and Mach number rise. This is the delta-V conundrum.
delta Burn reverses that paradigm. Our technology improves relative efficiency at higher speeds and altitudes compared to any standard system.
Turboprops and turbofans will see lower power demand at takeoff & cruise, cooler engines, and quieter operation. Turbofans gain higher bypass efficiency, improved thrust-specific fuel consumption (TSFC), and equally reduced emissions. Helicopters, are a subject all to themselves, best discussed elsewhere!
The Technical Edge: Respecting Rules. Avoiding Limits.
To all turbomachinery specialists: deltaBurn doesn’t break any aerodynamic laws that have governed designs for a century; instead, we avoid the assumptions that have imposed ceilings on efficiency.
On the blade itself, our modifications subtly alter circulation and lift distribution; in the bypass flow, downstream of the fan, a sequence of changes compounds into a surprising outcome — call it a sleight of hand card trick. What was once thought impossible has now become practical, repeatable, and certifiable.
Proof, Not Theory: Flight tested. Certification in Progress.
The effects of our technology have been demonstrated in controlled testing, with ground test runs on turboprops and turbofans, and full flight test programs across multiple aircraft types. Conducted demonstrations have been observed by Certification Verification Engineers, and engine OEM Program Managers.
Results are consistent: fuel burn reductions of up to one-third without loss of thrust. Importantly, these gains are achieved without exotic materials, new cores, or high-risk redesign. This is a retrofit solution ready for today’s fleet. Certification of the first products is underway.
Environmental & Economic Impact: Sustainability that Pays for Itself.
Our technology forms both an operational and an environmental breakthrough. Airlines and operators can cut costs immediately while significantly contributing to global decarbonization goals.
Fuel burn reductions of up to 33% at same thrust. CO₂ and NOₓ reduction directly proportional to fuel burn reduction. Engine health greatly improved through lower operating temperatures, lower stresses, and extended service life. Return on investment measured in months, not years. Again, this is not a future promise this is technology that is available today.
We don’t make claims of what the technology may do, rather, we are committed to letting the data speak for itself. Our founder is not prepared to state a value less than what we see in testing:
“the technology gets the value it gets; we do not have a technology that gets less, it is what it is on the engines that we have tested; we’re not going to mislead the industry by stating a different value, higher or lower. It is what it is, and the engineers will have to revisit some theory”.
At deltaBurn, we believe that the future of aviation lies not only in new engines and alternative fuels, but also in making the existing fleet (that will fly aorund for another 50 years) dramatically more efficient. This future is possible now.
DeltaBurn: the future of propulsion, flying today.
The largest single step in propulsion efficiency since the advent of powered flight is here (not our quote, by the way).
Flight tested, demonstrated; ready to reduce operating costs and emissions across the global fleet, with certification underway.
