Introduction to Aviation (2) Flight Controls

okay come back it’s fine for us so in this lesson in the last class we were introduced to this table in this lesson people for details of the tailplane horizontal stabilizer and the vertical stabilizer firstly the elevator elevator is that is the interrupt time maintaining a straight and level flight and descending all these movements are controlled by the elevator it undergoes severe extremes of loads it’s a very important so in this state of very very minor changes in future lessons here explain to show the working of the

elevator the moment of the elevator in the graffiti mom for you are better we’re next country circus which we are going to see is the rudder the rudder controls the yaw of the nose of the aircraft and it is controlled by them it is operated by the rudder pedals which will be operated by the pilot by his foot in the cockpit so the rudder pedals are operated in net to and fro motion for axis moves to the next to the left direction similarly with another where the direction reverses entity operates the right leg forward obviously the left pedal will come back by them when the right pedal is pressed forward then the rudder right so this is again a very important control surface which provides three direction control here I try to show the working of the here I put a picture of another control of a firebase jet for you understand that next control which we are going to talk about is the gala we already been introduced to this previous lesson there are two ailerons fixed on the outer edge on either side of the main wings and they control the rolling movement of the and it is operated by the control column by its way Santa clockwise to and fro motion rolling motion in this picture we can see the aileron control of a large jet detector in many smaller planes this arrow will be a single piece controlled by the control column but in this case you can see that this it is in two different pieces which is called the speed tail it has got some advantages which is beyond the purview of this lesson but suffice to understand that railroads so this is the one the picture has been shown is this bit of a logic yeah I try to show the movement and control as controlled by the control column of the Elrond in the rotary motion and the motion of the rail not per se to give you a better understanding so far we saw three country surfaces that is available the elevator and the

later these three constitute the primary surface of the plane which functions see the first one which we I want to introduce you in most modern capped this horizontal stabilizer is is is a movable stabilizer it is operated electrically from the control column by pressing a switch it goes in the up and downward motion as shown here what I wanted is that when they’re there this high-performance planes have change in speeds during the night the real-world force which we call the crab for the flight is keeps varying and increase so normally they would be neutralized by the movement of the elevator but that doesn’t serve one whole purpose the movable horizontal stabilizer will enable reduction in this track this track is called the true graph so which eventually leads to better fuel efficiency the next important to come to a service which I explained is the caps these controls which are slashed normally under the mean they are tax structures they come out protruding down and drooping dumb Birds then operated the flaps are usually used for the takeoff and the landing phase what are the advantages they improve the lifting capability of the wing so that the aircraft doesn’t use one whole lot of runway length that means it is able to lift up in within their underlings available at that particular oil filter even though the rearward force the drag force which which we talked about earlier also is going to increase because of in this of the of course they are so the next control [ __ ] Here I am going to talk about the slaps these slacks are fixed to the leading edges of the wings they have a very similar profile and shape often of a big thing but in a very small dimension giving it the advantages of its shape they are operated by a single which operates the and they operate in in the stability

the next control which I am going to talk about is the speed brakes speed brakes are flat panels which protrude out as sure if they come out during the flight and especially during landing the function it performs is that it it disrupts the airflow over the beam not only the over the wing the airflow would be very smooth and linear without any disturbance now this speed brakes when they protrude out they create a lot of disturbance in the airflow they are fine they are able to increase the drag the real-world folds which we have been talking about and they are also able to trick the lift being generated that means upward folds on the wings being generated so they dump quite a lot of lift and increase drag which is why it’s called the speed brakes so if they have had to be having any speed it will decelerate immediately therefore it is very effectively used during the lighting traces of the plane and during flight if you have to reduce speed it will be useful to operate the speed brakes to quickly reduce the speed and also by using the speed brakes differentially over both the both the wings the turning capability otherwise very large resilience to turning it may not be very easy to turn carbon so speed brakes aid in aircraft turning as well I put a picture of a plane where the speed brakes have been operated and of course the plants also have been lowered as you can see and I also followed it up with the video which I took alive with the speed brakes and the flat square operated during a landing phase of the light switch I hope you can see that the following as we follow the the last control surface which I want to explain is the term taps these are all small taps attached to the primary and secondary control surfaces which which are operated by small electrical switches in the cockpit or mechanical turn from wheels in the cockpit they they they they are every to reduce the control surfaces spent the aircraft is in a transit position or if it’s in an out of trim position what happens is

when you operate the primary flight control surfaces there is a pressure which is exerted on the control column the pilot usually has to keep it holding for some time which is not possible all throughout the flight therefore these additional forces which are generated have to be trimmed off or reduced this is enabled by these trim times the detail working of it is beyond the approving of this lesson but suffice to understand that they enable smooth and reduced workload for the pilot in operating the control surface we come to a conclusion of this lesson control surfaces this is a brief introduction of course for a professional who is involved in flying he he will learn much more in detail as a starting point these gimmicks of higher understanding like suppose for any aspiring any aviation enthusiast once again I thank you for going through the laser patiently and please feel free to to offer your comments on the d-mail actors which has been given under end of the slide thank you once again
