Airfoil Design for Mars Aircraft Using Modified PARSEC Geometry RepresentationMasahiro Kanazaki
The document describes a study that used computational fluid dynamics and genetic algorithms to optimize airfoil designs for aircraft intended to fly on Mars. The study represented airfoils using a modified PARSEC method and evaluated designs based on their maximum lift-to-drag ratio. The optimization process produced designs with higher lift-to-drag ratios than the baseline design, achieving this through design changes like smaller leading edge radii, increased camber, and more relaxed upper surface pressure recovery. Visualization of the results provided insight into which design parameters most affected lift-to-drag ratio. The study demonstrated an efficient method for exploring unknown airfoil design problems to achieve higher performing designs for Mars aircraft.

Linearization involves developing a linear approximation of a nonlinear system around an operating point. This allows tools from linear systems theory to be applied to analyze and design controllers for nonlinear systems. Specifically, Taylor's theorem is used to expand the nonlinear functions as a linear combination of deviations from the operating point. The resulting linearized model is only valid locally but provides an approximate way to analyze system behavior if well-controlled near the operating point. Examples show how to derive linearized models for common nonlinear systems like tanks and chemical reactors.

11. Descriptor
Sound power, including direction dependent level adjustment: Lw,dir
Sound pressure level at receiver:
Lp (f, , ,r) = Lw (f) + Dc(f, , ) - C - A(f,r)
Lp (f, , ,r) = Lw,dir (f, , ) - 11 - A(f,r)
Sound pressure level at 1 m in free field (A 0):
Lp (f, , ,1m) = Lw,dir (f, , ) - 11

16. Data base structure
Tables for specific aircraft and operation
conditions may be arranged in a data base
Not all combinations of operation conditions will
have data typical configurations with data,
rest with default values
Not all aircraft will have data grouping of
acoustically similar aircraft and substitution of
acoustically less important aircraft

Empa, R. Bütikofer, October 2006 18
19. „In-flight“ measurements under operational
conditions (I)
Set – up
Several microphones perpendicular to the axis
of the runway
at 3 to 5 km after brake release (departure)
at 1 to 3 km prior to touch down (landing)
Measurement of the normal airport traffic during
several days

20. „In-flight“ measurements under operational
conditions (II)
Requirements
Precision tracking of aircraft (tracking radar or
optical)
Time synchronisation of position and of the
acoustic recordings
Exact aircraft identification (type, engine, carrier,
ATOW)
Information from carriers on flight procedures
Empa, R. Bütikofer, October 2006 20
21. „In-flight“ measurements under operational

22. „In-flight“ measurements under operational
conditions (VI)
Disadvantages
Thrust is unknown (unless FDR recordings are
available)
Limited to specific parameter combinations
(speed, flaps, gear, thrust)
Measurements only close to the airport
(sufficient signal to noise ratio)

Empa, R. Bütikofer, October 2006 24
25. Arranged „In-flight“ measurements (II)
Requirements
Airfield reserved for measurements
Aircraft available for test flights
Advantages
Well controlled measurements
Various lateral angles by varying the flight level
Empa, R. Bütikofer, October 2006 25
26. Arranged „In-flight“ measurements (III)
Disadvantages
Expensive

31. Processing of measurements (I)
1/3 octave band processing, retaining exact time
For many discrete aircraft positions: combine
geometry ( , , ,r) with measured spectrum.
„Depropagate“ the spectra for Lw,dir ( , ):
Calculate propagation for the specific geometry, using
temperature and humidity of the measurement day.
Subtract propagation from measurement
Empa, R. Bütikofer, October 2006 31
32. Processing of measurements (II)
For each 1/3 octave: Average and interpolate
Lw,dir ( , ) in the spherical coordinates and
Generate look-up tables Lw,dir (f, , )
Validate results by reproducing measured data
