The objective of this project is to demonstrate the feasibility of an efficient "diesel" engine installation on a FAR/EASA Part23, 9 to 11 seats twin engine aircraft configuration and reduce as much as possible the related increase in drag, respect to a conventional engine, by using Computational Fluid Dynamics (CFD) in the design phase.
In order to achieve this goal the SR460, a six-cylinders, air/oil-cooled turbo-diesel engine produced by SMA, will be used as reference and installed on the TECNAM P2012 TRAVELLER aircraft.
The main advantages are are:
Decrease in average fuel consumption;
Capability to use both "Avgas" and "kerosene".
IL CIRA contribuisce al progetto effettuando analisi di aerodinamica computazione per affrontare le problematiche legate all'integrazione gondola motore, le prese d'aria e le problematiche di raffreddamento.
CIRA contribution is mainly the aerodynamic design of engine/airframe integration, air-intake and engine cooling issues studies.
