Multidisciplinary optimization of Aircraft Actuation System for Conceptual Analysis

Development of a Multidisciplinary Design Optimization Framework Applied on UAV Design by Considering Models for Mission, Surveillance, and Stealth Performance

“…A number of MDO frameworks have successfully included TORNADO as the main tool for aerodynamic predictions mostly due to its fast computational speed and its modifiable interface which enables a simple integration [35], [30]. Smith et al [30] performed an aero-structural wing optimization, while Safavi et al [35] used TORNADO for initial aircraft design optimization coupled with a dynamics model.…”

Smith et al [30] performed an aero-structural wing optimization, while Safavi et al [35] used TORNADO for initial aircraft design optimization coupled with a dynamics model. It is noted in [30] that there are limitations at high AoA but nevertheless, the linear aerodynamics theory is valid for normal aircraft operating conditions such as those of cruise, climb, decent, landing, and take-off which have also been considered in the present case-study.…”

“…The obtained results from the real-and meta-models were evaluated and the output in both cases was found to be in good agreement. A more thorough investigation and implementation of metamodels is presented in the case-study of Safavi et al [35]. In this case, the authors used modeFRONTIER to create metamodels of all the simulation models of an aircraft MDO framework by using the "Anisotropic Kriging" algorithm and the "Uniform Latin Hypercube (ULH)" sampling method.…”

Multidisciplinary Design Optimization of Aerial Vehicles: A Review of Recent Advancements

“…An aircraft is a complex product that is typically comprised of many subsystems which interact with the airframe as well as with each other, and hence, aircraft systems are inevitably a design driver that must be 5 International Journal of Aerospace Engineering taken into account as early as possible in the development process [23,46]. Nevertheless, aircraft systems are seldom considered in MDO, and apart from the complete study of [82], the rest of the papers either neglect them or focus only on a few specific aspects like for example the hydraulics [83], the environmental control [76,84], the fuel supply [27,84], or the landing gear [46,85]. Overall, it can be observed that in conceptual design it is common to model systems with simple equations which can predict the basic properties at a low computational cost, however, in detailed design, it can be seen that this approach is no longer adequate since it is critical to know the exact performance of each component [84].…”

In this respect, it has been shown that including a detailed system representation and performing a simulation-based optimization can generally offer significant knowledge on the design [76,82,84], while at the same time, it is also possible to use the geometry in a collaborative way in order to identify the optimum layout [46] or detect unwanted issues that might arise during placement [27,83,85].…”
