Here are some useful papers related to aircraft conceptual design:
 | "Spreadsheet Methods for Aircraft Design", AIAA-89-2059, July/August 1989.
In the mid-1980s spreadsheets (such as Lotus 1-2-3) were used on personal
computers for accounting. When Jeff Durrie returned to Lockheed to head
up the conceptual design group for the National AeroSpace Plane (NASP) project, he
introduced the use of spreadsheets for back-of-the-envelope mission analysis
(since no other simple tools were available for airbreathing
single-stage-to-orbit vehicles). Spreadsheets were later used for
post-processing output from the mission sizing program Hypersonic Aircraft
Sizing Program (HASP). HASP was a modification of the standard Lockheed
aircraft sizing program Advanced Systems Synthesis and Evaluation Technique
(ASSET). This paper was the first documentation on the use of
spreadsheets for aircraft sizing, constraint optimization, CG limits, and
horizontal stabilizer sizing. |

"Zen and the Art of Airplane Sizing", SAE Paper 931255, 1993.
This paper describes the use of a pocket calculator for aircraft sizing.
This is not something that you would normally want to do, but the paper was
written as an exercise to reduce the aircraft sizing procedure to its most
simple elements. In this respect it's a useful explanation of the
rudiments of matching the empty weight available from mission analysis (We(available))
to the empty weight required (We(required)) based on the aircraft
configuration. |
| Carpet Plots. This is
brief description of how to draw carpet plots. There's an obvious
typographical
error in that the plots don't show x=yz but rather y=f(x,z). Otherwise
this is a useful primer. |
| A description by Sid Powers on how to construct a carpet plot using a
spreadsheet may be found on Bill Mason's website at Virginia Tech at
http://www.aoe.vt.edu/~mason/Mason_f/SD1CarpetsbySAP.pdf. This
procedure is still bit clunky, and Excel won't draw smooth lines between the
points, so these would have to be hand-drawn. |
