The application scope of unmanned aerial vehicles (UAVs) is increasing along with commensurate advancements in performance. hybrid quadrotor vertical takeoff and landing (VTOL) UAV has the benefits both rotary-wing aircraft fixed-wing aircraft. However, vehicle requires a robust controller for takeoff, landing, transition, hovering modes because aerodynamic parameters differ those modes. We con...

In busy airports, too many departing flights take off out of the time slot required by the Central Flow Management Unit (CFMU). During ground traffic peaks, taxi out times and runway queuing delays increase, and it seems very hard and maybe unfeasible for ground controllers to organise properly the traffic so that aircraft take off at their scheduled time. In a first part, this paper shows how ...

Knowledge of the fuel flow rate is important for accurate fuel burn and emissions inventory generation and for accurate engine performance modeling. In this paper, machine learning techniques are applied to aircraft flight recorder data to model the fuel flow rate as a function of the aircraft altitude, ground speed, vertical speed, and takeoff mass in the airborne phases of flight. Models are ...

In this paper, we discuss how the neighbors affect the decision of consumer behavior over diffusion of innovation. We suggest an agent-based model of diffusion and showed that on an online social network which have both of ”scale-free” and ”small world” properties, 1) the informative effect can cause a takeoff, but it is not sufficient to reach the completion of diffusion. 2) Meanwhile, the com...

1 INTRODUCTION Micro Aerial Vehicles (MAV) form a comparably new area of aeronautical research. This type of aircraft is defined by takeoff weights typically less than 500 g and very small dimensions, e.g. wingspans under 50 cm. Intense research is conducted worldwide to further reduce MAV mass and size (e.g. Within this paper, this term is expanded to also include so-called miniature unmanned ...
