The improvement of the aerodynamic performance of UAV/UCAVs can be achieved by optimising the aerofoil shapes for the aerofoil sections (2, 5, 8, 17, 22) and wing planform
(3), (12, 13, 25).
The X-45C Air Force design will be based on the subsystems and center body of Boeing's current X-45B design, but it will incorporate a revised planform
that carries more fuel and provides better aerodynamic performance.
The teams are limited as to the overall size - planform
- of their craft, and can chose between two engine types.
I instantly looked up to see the planform
on the lead aircraft (which was breaking left), covering up my entire windshield and half of the canopy
The results of this examination revealed that, besides local increases in river width throughout the mined area on the Bouie, the planform
of these rivers appeared to have changed very little over the years.
This study describes the nature of channel planform
change that occurred in three contiguous alluvial reaches of the Brazos River, Texas, from the 1930s to 1988.
Starting from a basic knowledge of mathematics and mechanics gained in standard foundation classes, Theory of Lift: Introductory Computational Aerodynamics in MATLAB/Octave takes the reader conceptually through from the fundamental mechanics of lift to the stage of actually being able to make practical calculations and predictions of the coefficient of lift for realistic wing profile and planform
We do not understand to what extent present estuary planform
shape and shoal patterns resulted from biomorphological processes interacting with inherited conditions and interference.
Becker described work being done on a triangular planform
that would use lift during re-entry to provide great flexibility in landing sites.
Boeing is offering the X-46, a design whose planform
resembles that of the B-2 bomber.
The tributaries are very narrow (7 - 8m) in planform
and of second/third order with first order tributaries at their head.
The Sensor Craft concept of a UAV optimised for sensor performance, perhaps through the use of a 'hollow diamond' planform
, is also being studied.
