How does a spacecraft resist burning up from extreme heat?
As a spacecraft enters the atmosphere, it will travel at a tremendously high speed. The friction from the air rubbing against the spacecraft causes lots of heat. To protect against this heat, spacecraft use heat shields. Most spacecraft use blunt, spherical, or conic heat shields which help slow the vehicle down, and dissipate the heat in the surrounding air. These heat shields are also usually made out of abalative material. Abalative materials sublimate into gas at high temperature. As a result, they absorb thermal energy but erode away as the vehicle enters the atmosphere. However modern spacecraft are being developed to have re-usable heat shields. The Space Shuttle, in particular, uses a series of thermal insulating tiles that absorb and radiate heat while preventing conduction to the shuttle's aluminum skin. These tiles can be re-used many times.

A heat shield on a space craft protects the craft from burning up or malfunctioning from over heating.
hot weather Temperatures that hover 10 degrees or more above the average high temperature for the region and last for several weeks are defined as extreme heat. Humid or muggy conditions, which add to the discomfort of high temperatures, occur when a "dome" of high atmospheric pressure traps haz…y, damp air near the ground. Excessively dry and hot conditions can provoke dust storms and low visibility. Droughts occur when a long period passes without substantial rainfall. A heat wave combined with a drought is a very dangerous situation. ( Full Answer )

The heating element in the electric kettle will be primarily pure resistive. Power in that case is calculated P = E*I = 250V*I = 3000 W So the current is I = 3000 W/250 V = 12 Amps If there is anything else (lights, radio, PC, etc.) on the circuit that may be taking some current you are ver…y likely to go over 13 A frequently. I don't know how accurate you can expect a fuse's blow point to be. Perhaps +/- 10%? Doesn't seem very trouble free. Even if the circuit is dedicated to the kettle, consider this idea. We don't know exactly what conditions the manufacturer was considering when specifying the wattage. Probably operating conditions, when the element was hot. Then Ohm's Law tells us that the resistance R is R = E/I = 250 V/12 Amps = 20.8 Ohms But the element's resistance would be lower at first when it is cold. My calculations indicate that if the element is made of nichrome wire, and if the temperature change is 200 degrees C, the hot resistance of 21 Ohms is probably about 1.7 Ohms higher than when at room temperature. If that is true, when you first turn it on, Ohm's Law says that the initial current should be 12.95 Amps. Regardless of this analysis, remember that the fuse requirement is based on the size of the wires in the wall. You don't want those wires to get hot. Don't put in a bigger fuse than what was there originally. ( Full Answer )
No, polyester cannot resist heat. No object can 'resist' heat of any kind. Polyester can resist heat up to a certain point, which may only be a few degrees, but no object can fully 'resist' heat.

One lead will go on the braided shield (this is essentially the ground), the other lead goes on the heating conductors. Megger either one lead at a time, or both conductors under the same lead. I usually test at 1000v - follow manufacture's spec if unsure. You cannot test line to line with a megge…r. Testing line to line with an ohmmeter is of some use, as the ohmic value will be dependent on the length, wattage and, to some degree, the temperature of the heat trace. This test is most useful with more than one run of identical heat trace, or to track one piece over time. Values far outside of what is expected will indicate damaged (open or shorted) heat trace.

The Space Shuttle thermal protection system (TPS) is the barrier that protects the Space Shuttle Orbiter during the searing 1,650 Â°C (3,000 Â°F ) heat of atmospheric reentry . A secondary goal is to protect from the heat and cold of space while on orbit. Materials The TPS covers e…ssentially the entire orbiter surface, and consists of seven different materials in varying locations based on amount of required heat protection: Reinforced carbon-carbon (RCC), used in the nose cap, the chin area between the nose cap and nosewheel doors, and wing leading edges. Used where reentry temperature exceeds1,260 Â°C (2,300 Â°F). High-temperature reusable surface insulation (HRSI) tiles, used on the orbiter underside. Made of coated LI-900 Silica ceramics. Used where reentry temperature is below 1260 Â°C. Fibrous refractory composite insulation (FRCI) tiles, used to provide improved strength, durability, resistance to coating cracking and weight reduction. Some HRSI tiles were replaced by this type. Flexible Insulation Blankets (FIB), a quilted, flexible blanket-like surface insulation. Used where reentry temperature is below 649 Â°C (1,200 Â°F). Low-temperature Reusable Surface Insulation (LRSI) tiles, formerly used on the upper fuselage, but now mostly replaced by FIB. Used in temperature ranges roughly similar to FIB. Toughened unipiece fibrous insulation (TUFI) tiles, a stronger, tougher tile which came into use in 1996. Used in high and low temperature areas. Felt reusable surface insulation (FRSI). White Nomex felt blankets on the upper payload bay doors, portions of the midfuselage and aft fuselage sides, portions of the upper wing surface and a portion of the OMS/RCS pods. Used where temperatures stay below 371 Â°C (700 Â°F). Each type of TPS has specific heat protection, impact resistance, and weight characteristics, which determine the locations where it is used and the amount used. The shuttle TPS has three key characteristics that distinguish it from the TPS used on previous spacecraft: Reusable. Previous spacecraft generally used ablative heat shields which burned off during reentry and so couldn't be reused. This insulation was robust and reliable, and the single-use nature was appropriate for a single-use vehicle. By contrast, the reusable shuttle required a reusable thermal protection system. Lightweight. Previous ablative heat shields were very heavy. For example the ablative heat shield on the Apollo Command Module comprised about 1/3 of the vehicle weight. The winged shuttle had much more surface area than previous spacecraft, so a lightweight TPS was crucial. Fragile. The only known technology in the early 1970s with the required thermal and weight characteristics was also so fragile, due to the very low density, that one could easily crush a TPS tile by hand.

There are two factors that heat up meteors to the point of incandescence. We normally think of it as "friction", the super-fast rock rubbing along the still air. There's an element of that, but the primary mechanism for the heating is compression. Whenever materials are compressed they heat up - and… the more compression, the more the heating. Air cannot move faster than about 800 miles per hour. When a space rock going at 100,000 miles per hour smashes into our atmosphere, the air can't move out of the way; it compresses the air into an essentially solid wall. ( Full Answer )
