Hi would please clarify what do you mean by leading and trailing edges are difficult environments for installation WHENEVER THE FLAPS AND SLATS ARE EXTENDED 2:40 timing video
When leading edge slats and trailing edge flaps are in the stowed position, componants located in the space between the moving elements and the main wing are not exposed to the air stream and any contaminants carried along with the air stream. When the moving elements, slats and flaps are deployed, these componants are exposed to a very turbulant air stream. They are typically deployed near or on the ground at high landing speeds.
[edited] Connectors typically have multiple contacts, or pins. These pins come in many different designs, but are often a male-female configuration. Vibrations, incorrect disconnecting & reconecting, and thermal cycles can degrade the spring loaded contact between the mated pins, or there precise fit. A bad fit increases the resistance (impeadance), which in turn, could generate heating of the contact area in higher currents/amps circuits. The result is a bad contact, which presents as voltage drop, or voltage inconsistancy. This is called "chattering"
@@trespire Hello, I appreciate your efforts to reply to my friend, but be careful with your approach, as I assume you're not from the teaching field either. Saying, by assumption, that someone doesn't know about a subject doesn't help to create a legal link to explain content, think about it. It was not a nice way to show respect for the proposed questioning.
@@heberzunarelli Thanks for the feedback, but I don't speak legalese, nor have any inclination to do so. While I don't teach in accademia, I do train profesionals in the metal fabrication sector. All my trainees are grown adults, and I treat them as such. Frankness and directness yealds the best results. If someone doesn't know something, or didn't understand my explanation (often my fault), trainees are encouraged to speak up, & I'll repeat the explanation. I've consciously adopted a short/concise style of explaining, no tip toeing around peoples feelings and egos, including my own. 100% technical and data driven, as industrial processes have no feelings or sentiments.
@@trespire Industrial processes don't have sensations or feelings, but people do. I've also worked with technical training in aviation for many years, and I'm also a lecturer at a university. It's logical that you can say at the start of a conversation that someone "doesn't have any knowledge about that subject", but it's not the best method applied by the leading researchers of techniques for conducting presentations, training, classes. I don't expect you to agree with me, not least because you already believe that the best results for you are obtained this way. Life goes on, success is what I wish you.
@@heberzunarelli Again thank you for your feedback. I agree that we (I) should consider people have sensations and feelings, as the human factor is at least 50% of the success. Sometimes I lose patience when training the same customer some basic fundamental principals over and over. I will make an affort to be more sensitive & patient when dealing with people ! Again thank you.
Hi, I'm Héber. In fact, another person replied to your previous comments, not me (as you can see). My first language isn't English either, I'm Brazilian, we speak Portuguese.
@@blackhawktv1156 Hello. At 1:44 the narrator is talking about "chattering". This is a type of electrical fault of bad contacts under voltage/current. (Please see my previous response) Chaffing (not mentioned at 1:44) is a mechanical failure process in wiring and wire harnesses. If wires/harnesses/loom are free to move and rub against each other, the friction often will damage the insulation, exposing the conductors and resulting in an electrical short. The solution to prevent chaffing is securing wires / wire bundles / wire harnesses / wire looms correctly, so there is no possibility of them rubbing against each other, or rubbing against metal componants (structural bulkheads, longerons etc..) Other solutions to high vibrations and high G-loads are : Wireup, lacing, braded sheathes/sleeves, potting of componants and wiring looms. Hope this helps.
@@heberzunarelliHey could you provide me with more informations on Pressure Seals or VP? And the compound that separates pressured zones from non-pressured
Nice!
You can use titanium flexible tubes to protect these cables

I think you make a wrong judgment what I have asked for is the maining of chattering (is it chaffing) coz english is my second foreign language

@@yassinedarbal-8683 Hello. The compound used to seal structural elements, such as bulkheads, is PR 1750.
Integral fuel tanks are sealed with PR 1422.
