Helicopter phase lag
Web18 dec. 2014 · You look for the index where c is maximum ([maxC,I]=max(c);) and then you get your lag value in units of samples lag = lag(I);. This approach gives you the average phase lag for the entire recording. It requires that your signal of interest in the recording be stronger than anything else in your recording...in other words, it is sensitive to noise and … WebIn the aerodynamics of rotorcraft like helicopters , phase lag refers to the angular difference between the point at which a control input to a rotor blade occurs and the point …

WebPhase lag (rotorcraft) In order for a helicopter to roll left (see flight dynamics) intuition would tell us that we require maximum lift on the right and minimum lift on the left.That is, … WebPhase lag is a property of all rotating systems acted upon by a periodic force. Because of phase-lag, rolling a rotorcraft to the left or right would theoretically require a forward or …
WebFor a helicopter to hover, the lift and thrust produced by the rotor system act straight up and must equal the weight and drag, which act straight down. [Figure 1] While hovering, the amount of main rotor thrust can be changed to maintain the desired hovering altitude. This is done by changing the angle of incidence (by moving the collective ...
