CEASIOM

CEASIOM framework, stands for Computerised Environment for Aircraft Synthesis and Integrated Optimisation Methods, is the outcome of EU PF6 Project SimSAC, it aims on the conceptual-preliminary design stage, and focusing on bringing the S & C earlier into the design.

Here is a design story carried out by CEASIOM.

Some studies done by Airinnova using CEASIOM Suite are shown here.

1. Aerodynamic optimization:

A blended-wing-body configuration proposed by EU project MOB is supposed to cruise in transonic speed with cruise CL = 0.3. The original geometry was provided by German Aerospace Center (DLR) and it has significant shock waves. The optimized design has a drag reduction by around 45% for a trimmed flight with the constraints on (1) CL = 0.3 (2) fixed planform (3) preserved wing volume in the central part.

Wave drag reduction on a flying wing for transonic cruise, Mach number 0.80, CL = 0.5
Wave drag reduction on a flying wing for transonic cruise, Mach number 0.85, CL = 0.3

 2. Computational aerodynamics

EARSM turbulent model, Mach number 0.78
EARSM turbulent model simulation on a regional jet, full scale model,  Mach number 0.78 at cruise

3. MIT D8 “double bubble” aircraft

“Fast” CFD for aircraft conceptual-preliminary design: Airinnova deliveries “fast” CFDs for various cases in a short time with high reliability:

    • from non-meshable wireframe model to high-fidelity computational results;
    • from standard CAD model to high-fidelity computational results and flight stability analysis
