| General note |
This research discusses the development of surrogate models for aircraft and rotorcraft design<br/>during the conceptual phase. The approach proposed in this study, on a crude scale, holds a<br/>strong utilization potential among the design community and aero modelers during the<br/>preliminary sizing. The fixed-wing aircraft database includes fighters, trainers, transport aircraft,<br/>agricultural planes, amphibious aircraft, light utility planes, motor-gliders, sport planes, and<br/>freighters. Similarly, the rotorcraft database comprises conventional, fenestron, counter-rotating,<br/>and no tail rotor configurations was developed from commercially available data. Linear/NonLinear regression modeling using power laws is carried out to explore highly correlated design<br/>trends among aircraft and rotorcraft weight, geometric, propulsion, and performance parameters.<br/>These design trends identify interdependencies among design parameters and provide initial<br/>design bounds for preliminary sizing. Aircraft and rotorcraft design is complex process, and a<br/>single variable can never predict the response with adequate confidence. Surrogate models using<br/>multiple linear regression techniques were developed to estimate aircraft and rotorcraft<br/>performance parameters: range, rate of climb, service ceiling, and maximum velocity. Moreover,<br/>these models are validated using a two-step process that includes verifying each model using<br/>quantitative criteria and checking the prediction accuracy of each model. |
