Now open technology, Humberto’s invention of a whispering turbofan, fuel efficient aircraft engine, is submitted for worldwide competition to develop a simulation capable of being used to optimize the design of a prototype.
The wining team, university or researchers, will become co-authors with TeknoX in accordance with our Terms and Conditions.
While the principal purpose of the design is to eliminate aircraft noise, the natural open loop heat regeneration also provides opportunity for fuel economy.

The Whispering fanjet technology (VPx) project
The purpose of this project coded VP600 is the development of a simulation to ultimately lead into the design of a prototype for proof of concept. Fundamental geometry and performance of a design point must be extrapolated to off-design performance. Tabulation of data must be supported with proper graphical display. Contrary to standard turbofan simulation, the VPx simulation starts with the definition of a turbine shaft power output to allow direct comparison with the PT6A-34 turboprop. The VP600 incorporates open loop heat regeneration (HR) and a heat exchanger (HE) design. The inventor’s design probably was not producible without the recent advent of Electron Beam Manufacturing (EBM). This may be the principal reason why major engine manufacturers have not even attempted to implement such technology, in addition of certain unproven modern theories.
The VP600 possibly will deliver 32% fuel economy compared to the turboprop and 52% more efficient than the FJ turbofan series. Also, the VPx robust but simpler architecture may deliver a turbofan comparable in price with a turboprop system.
Since static test is only a reference number, the notably difference between the turboprop and the VP600 performance is the thrust available for full power climbout. At 135 mph MSL, the VP600 may outperform the PT6A-34 by more than 30%. Similar advantage is expected at cruise altitude.
