Aircraft conceptual design using genetic algorithms
8th Symposium on Multidisciplinary Analysis and Optimization, 2000Nomenclature Aircraft design is a complex multidisciplinary process to determine aircraft configuration variables that satisfy a set of mission requirements. It is very hard for aircraft designers to foresee the consequences of changing certain variables.

Conceptual design modeling by the novel aircraft conceptual design and analysis system (ACDAS)
Aircraft Engineering and Aerospace Technology, 2023Purpose Throughout an aircraft development process, the conceptual design phase is an extremely important milestone; hence, the quality and success of this step directly affect the overall cost and lead time of the project. Because of this fact, the purpose of this study is to provide outputs and suggestions to the designing engineer regarding the ...

Flutter Prediction for Aircraft Conceptual Design
AIAA Scitech 2019 Forum, 2019Flutter prediction is usually a knowledge-based analysis process that aims to reduce the cost of aeroelastic stability margin certification. However, early detection of flutter problems is beneficial in the development of unconventional aircraft. The recently developed automation tool ConceptFEA for structural sizing of aircraft concepts paves the way ...

Adaptable conceptual aircraft design model
Advances in aircraft and spacecraft science, 2014This paper presents a new conceptual design model ACAD (Adaptable Conceptual Aircraft Design), which differs from the other models due to its considerable adaptability to the different classes of aircraft. Another significant feature is the simplicity of the process which leads to the preliminary design outputs and also allowing a substantial autonomy ...

Special Systems Considerations in Conceptual Aircraft Design
AIAA AVIATION FORUM AND ASCEND 2024Special operations air vehicle like military aircraft are often composed of special configurational items and mission equipment like variable sweep wing or radar systems. In conceptual aircraft design those systems are not always considered in particular. Further, for such equipment and systems only a very few data are available for the layout. Despite

Optimal Conceptual Design of Transport Aircraft
11th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2006An efficient framework for multi-disciplinary design and optimization of transport aircraft was elaborated and developed. Semi-empirical methods were employed for wing weight estimation; a multi-block full-potential code was used for drag calculation and maximum-lift coefficient estimation; a calibrated single-point Breguet simplified equation was ...

Emissions Prediction for Aircraft Conceptual Design
48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012Future stringent emissions regulations will require more accurate emissions prediction capability. To reduce design risk, emissions prediction capability must be brought forward to the conceptual design phase, to allow for system level assessments and to allow for parametric variations in combustor geometry for different low-emissions combustor ...

Incorporating and Minimizing Aircraft Noise Annoyance During Conceptual Aircraft Design
20th AIAA/CEAS Aeroacoustics Conference, 2014The assessment of aircraft noise for community noise impact and certification has till now been performed conventionally using the A-weighted decibel (dBA) and Effective Perceived Noise Level (EPNL) metrics respectively. Although these metrics have sufficed till now for conventional noise assessment, the renewed interest in unconventional engines such ...
