With the gearbox, propeller and hydrofoils defined, we then created the undulation system, which would enable the force generated by propeller, and transmitted by the gear, to cause the hydrofoils to change their angle of attack
in the trawls executed by the vessel (Fig.
As previously mentioned, the angle of attack
is varied from 0[degrees] to 180[degrees] with an increment of 2[degrees], making a total of 46 angles of attack for each configuration.
Figure 5 presents the dependence [bar.[i.sub.0]] = f([bar.i']), the analysis of which demonstrates that hysteresis by critical angle of attack
occurs in different values of inability to calculate the flow at [bar.i'] > 1.
The combined spanwise average Nusselt number for the rectangular wing at an angle of attack
of [beta] = 26[degrees] and Reynolds number 100 is 35.38 % higher than that of the plain duct at location X=2.24.
The [C.sub.L] presented the maximum values at an angle of attack
of 45[degrees] ([C.sub.L] [approximately or equal to] 0.6).
Flight tests with this F-18 Harv (High Alpha Research Vehicle) from 1987 to 1996 included Herbst turns and the use of an offensive descending spiral inside the flight path of a tightly turning conventional opponent, tracking the target for up to ten seconds and a 60[degrees] angle of attack
The same level of importance is applied to the angle of attack
of the cutting edge of the plow.
Like the lawsuits against the asbestos industry, the fraud angle of attack
in tobacco litigation may take some trial and error fine-tuning before being packaged in its most compelling and effective light.
Reporting in the June 14 SCIENCE, they confirmed that rapid changes in a dragonfly wing's speed and angle of attack
do indeed generate vortices and unsteady flows.
"The disagree alert was tied or linked into the angle of attack
indicator, which is an optional feature on the MAX.
In the original design, MCAS used data from one of two angle of attack
indicators to determine the deflection angle of the horizontal stabilizer.
According to the (https://www.nytimes.com/2019/03/21/business/boeing-safety-features-charge.html) New York Times , the jets were missing features that would have helped the pilots detect dangerous readings. The crafts were brand new (https://www.ibtimes.co.in/boeing-reshuffles-top-engineers-amid-737-max-crisis-794205) Boeing 737 Max planes but were missing the angle of attack
indicator or an angle of attack
Angle of attack
sensors on the aircraft tell the MCAS to automatically point the nose of the plane down if it is in danger of going into a stall.
If there were some way I could make a series of trips back in time to change things, one of the stops on my itinerary would be to somehow infiltrate the small cadre of early pilots and airplane designers to convince them to use a word other than "stall" to describe what happens when a wing exceeds its critical angle of attack
. The word obviously has numerous other applications, and using it for this purpose has confounded student pilots and television news anchors ever since.
