Introduction 1. New technologies are bringing new challenges to aircraft of quite a few scales. Whilst flight New technologies are bringing new challenges to aircraft of many scales. Whilst flight manage actuators for massive, inhabited aircraft have been around due to the fact Sperry’s autopilot first control actuators for huge, inhabited aircraft have been about considering the fact that Sperry’s autopilot took to theto the air than a than a century ago, small flightactuators are nevertheless challenged [1]. first took air far more far more century ago, smaller flight manage manage actuators are nonetheless chalOne of your most daunting challenges ischallenges low actuator low actuator bandwidths. lenged [1]. Just about the most daunting related to is associated with bandwidths. Figure 1 is actually a Bode amplitude plot of many standard subscale flight control actuators. actuators.

Indeed, the vast majority of subscale aircraft actuators are built for toy airplanes and helicopters operating in environments like this. As subscale aircraft move more quickly and more rapidly and/or enter ever more challenging flight dynamics environments, greater and higher speeds are necessary. As aspect of a series of surveys performed within the 1990s supporting the DoD Micro Aerial Car (MAV) program, detailed surveys and studies of gust structures and intensities had been recorded in and about an urban atmosphere on a 50 atmospherics day [3]. The results displayed below demonstrate intense upset angles and frequencies for aircraft operating in urban environments. Clearly, upset gusts on the order of 10 kts peak-to-peak at 10 Hz are adequate to tax lots of f.
