While canopy sizes are frequently expressed in terms of diameter, the most important measure of size is the drag area
, which is the finished canopy area multiplied by the drag coefficient, according to the company.
It corrects a high drag area
of the airplane to more closely match the design of the 1970 and later Cardinals, improving airflow, rate of climb and cruise speed.
iii) Average drag area
result as calculated in 40 CFR 1066, subpart D) and all of the individual run results (including voided or invalid runs).
Figures 7 and 8 contrast the smooth-vs-turbulent flow yaw distributions of drag area
for the large car and standard SUV, respectively, performed at 110 km/h.
For comparison, a standard FGGE-type drifter had a drag area
ratio of 10-12 and a downwind slip of 8 cm/s in 10 m/s winds [21,22].
As also recently pointed out in the "Penetrator Development within framework of a Jovian Moon mission - Phase 2" activity (C213- 002PA) a relatively high drag area
is needed to get the required trajectory turn over.
The flight trajectory calculations also required an estimate of the drag area
of the ball, SCd.
So, when comparing vehicles of different sizes--or vehicles and door mirrors--the drag area
(CDA) should be used.
There are two main areas where street girls operate - The Drag area
in the city centre and the Calton-Glasgow Green area in the east end.
But since it is only affected according to the fourth root of drag area
, your best glide speed would drop by about 16 percent.
These instructions pertain to a spreadsheet that will allow you to determine aerodynamic drag area
(CDA) from six field trials.
Not only are the exterior surfaces taut and sleek such that there is flushness between the sheet metal and glass, there is even what Williamsen described as an "air kicker" molded into the lenses of the taillights: its purpose is to move the air so that it doesn't go to the drag area
formed in the rear fascia by the license plate indentation.
