Resistors: Resistor is an electrical component that provides electrical resistance to a circuit. Resistors are used to decrease the flow of current. Principle of Resistors: Ohms law: Ohms law states that the voltage across the resistor is proportional to current, where the constant of proportionality is resistance. Symbols of resistors are: Here a= resistor, b= rheostat and c is potentiometer. Types of resistors 1. Power Resistors 2. Variable Resistors Effect of temperature in resistor: 1. Metal conductor Temp and resistance increases with increase in temperature. Rt=Ro(1+alpha0t) positive temperature cofficient 2. Semi conductor Temperature increases and resistance decreases with increase in temperature. Rt=Ro(1-alpha0t) negative temp coffecient 3. Isulator Temperature increases and resistance decreases with increase in temperature.

 Belly flaps are one of the esential control surfaces in a BWB design. This developes a separation of pressure during take off which helps the aircraft to produce a desired pitching moment. as the aircraft takes on momentum the air undert the wind, in this case the whole aircraft produces lift and produces a nose up moment ( desired) to help with this pitching moment, belly flaps are deployed, this produces a separation of the high pressure air from reaching the aft of the aircraft and this further helping this nose up pitching moment. This is an important part of a BWB design because the BWB design doesnt have a tailplane ( elevator to produce high moment for pitching).

  Weight estimation in Aircraft design. Introduction before introduction: This is one the lectures that i am taking in Wintersemester 2020. I found this course to be very interesting (Advanced aircraft design 1). However interesting this course maybe, the examination process is also differnt. Instead of a conventional written exam, this exam will take place like a Viva. So this will be a different experience. I have had some exams in this form in Germany, however this form of examination really questions your understanding. and your skill of explaining. And i have come up with this idea of writing a blog for each of the chapter we learn in class. This is a good idea to me because the course not just requires me to understand the subject matter but also learn how to express an idea in a spoken form. I need to brush on my speaking skills as well. I find this challenging task however also necessary. So having said that i would like to start my one of the early blogs. :) Introduction: So t

  Introduction to ILS ILS is a ground based radio navigation system that helps in approach guidance in the inboard side of the aircraft. So it a procedure adopted by manny airports around the world to guide the aircraft to land safely even in harse weather conditions. It can be immagined like the rail guides that we find in airports during boarding. What this basically does is guides you throught the way. Terminologies relevant to ILS Before starting with the topic we need to understand some of the terminologies, one being the meterological conditions. So an aircraft approach in IMC ( Instument Meterological Conditions) or VMC (Visual Meterological Conditions) means the situation of weather condition that demands certain procedure. If the situation is IMC then we say the approach in IMC and if it is VMC then we say the approach in VMC.  Now lets move on to next terminology .i.e. VFR and IFR. these are the set of rules that need to followed according the MC. If the Approac is in IMC the
