That'd be thefull-scale X-65, built as a demonstration platform for a new technology that replaces all moving control surfaces with"active flow control" actuators. These blast jets of compressed air out of nozzles along the wings to change air pressure in specific locations and control the ...
Aortic dissection (AD) is one of the fatal and complex conditions. Since there is a lack of a specific treatment guideline for type-B AD, a better understanding of patient-specific hemodynamics and therapy outcomes can potentially control the progression
(16) that might potentially be affected by a change in planet’s spin rate. Since η e is a function of η(L) (Figure 7), first we need to investigate whether rotational speed can influence the equilibrium heat-storage coefficient η L at any latitude L. We begin with the mathematical...
Their research revealed that the movement of copper ions is the linchpin of an electrical conductivity change which can be leveraged to create electrical spikes in the same way that neurons function in the cerebral nervous system — a major step toward developing circuitry that functions like the h...

“Not one iota of change has been effectuated because of this last letter coming in,” said one local official, who asked not to be named. “All of the security precautions remain in place.” Those precautions were instituted after the San Francisco Chronicle received a letter Tuesday from ...
The necessity of producing a very solid analysis has forced to limit the deflection of the jet in a very conservative range (±15°) with respect to the horizontal. This range can be surely produced also by not optimal configurations and allow minimizing the use of DBD. From the study of ...
The results clearly confirm that wave surface can influence the aircraft landing performance to a great extent. The fundamental mechanism is found to be that the wave surface slope and wave particle velocity remarkably change the impacting position and effective impacting velocity of the aircraft. ...
ducted fan; ground effect; vertical takeoff and landing; aerodynamics1. Introduction Ducted fans can generate more static thrust when compared to open propellers of the same diameter and power loading [1]. In addition, the duct serves as a safety feature, protecting both the rotating blades from...
Indeed, in IGE conditions, as the aircraft rotates, the BW main wing moves away from the runaway whereas the rear wing approaches the ground; since the main wing is the most affected by the ground effect due to the closer distance to the runaway, a change in aircraft attitude leads to ...
