Description
Technical field
The utility model relates to a kind of Aerodynamic Heating and tests high-power quartz lamp radiant heat source electrode elastic coupling arrangement, in the time of the Aerodynamic Heating environment of the high-speed aircraft tests such as simulated missile, avoid the damage of fragile quartz lamp heating tube electrode, ensure the reliability of heat test environment and test data, the test simulation means of quick and safe are provided for developing high-speed missile and high-speed aircraft aerospace vehicle.
Background technology
Along with high-speed aircraft design flying speed increases substantially, the high thermal environment being produced by Aerodynamic Heating becomes very harsh.If when the high-speed aircraft such as guided missile, spacecraft flies with 6 Mach numbers, the transient heat flow density on its high-speed aircraft front-end case can exceed 1.2Mw/m
2, temperatures at localized regions can be up to 1200 DEG C.So exceedingly odious high thermal environment condition, makes the thermal protection of high-speed aircraft material and structure and calorific intensity problem become the key issue concerning development success or failure.The high temperature that when high-speed flight, serious Aerodynamic Heating produces, can significantly reduce the strength degree of hypersonic aircraft material and the bearing capacity of Flight Vehicle Structure, make structure generation thermal deformation, destroy the aerodynamic configuration of parts and affect the security performance of Flight Vehicle Structure.For ensureing the safety of high-speed aircraft, thermal shock and high temperature thermal stress damage that the material of confirmation aircraft and structure produce whether can stand high-speed flight time, must carry out Aerodynamic Heating analogue test and thermal strength test to hypersonic aircraft material and structure.This work has very important practical significance for thermal protection and the safe design of missile flight device.
The high thermal environment of high-speed aircraft is reappeared or the Aerodynamic Heating test method simulated can be divided into " convection type " and " non-convection type " two classes.For the thermal structure wind-tunnel of " convection type ", its advantage is Aerodynamic Heating environment and the shearing effect of air-flow to aircraft outer surface being produced by air-flow relative motion in simulated flight process more truly.But owing to adopting step thermal power ascending, descending mode to realize astable thermal environment simulation, carry out the overall evaluation with evenly heat power and mean heat flux, thermal structure wind-tunnel is difficult to the kinematic nonlinearity thermal environment of analog variation complexity.In addition, the experimentation cost of thermal structure wind-tunnel is very expensive, and single is short running time, be respectively 30-80ms and 25-220ms single running time of enthalpy shock tunnel as high in U.S. LENS and Muscovite U-12 wind-tunnel, therefore, thermal structure wind-tunnel can't be realized the whole process simulation that long-range hypersonic motor-driven aircraft reaches the Aerodynamic Heating experimental enviroment of thousands of seconds at present.
" non-convection type " is the thermal test method of taking heat exchange form with heat conduction or thermal radiation as the leading factor, wherein to adopt tungsten spiral filamentous processed as radiation source, be sealed in transparent quartz glass tube and switch on and send the morning of radiant type Aerodynamic Heating environmental simulation test technical development of strong Infrared, apply the most general.Because the infrared radiation type Aerodynamic Heating environmental simulation test technology of " non-convection type " has advantages of that some are outstanding: (1) quartz lamp pharoid heating power is large, volume is little, can form the heater of different size and shape, therefore be both suitable for small-sized material heat test, be also applicable to large-scale full-scale structure heat test.Therefore for the experimental piece of contour structures complexity, having good adaptive capacity, is the comparatively ideal radiant heating source of Aerodynamic Heating analogue test; (2) thermal inertia of quartz lamp pharoid is little, and automatically controlled function admirable is very suitable for the Transient Aerodynamic heating simulation changing at a high speed; (3) operating cost of quartz lamp radiation heating test is more much lower than thermal structure wind-tunnel, and the making of experimental facilities is relatively easy.Therefore, the relevant space flight and aviation research department of nowadays American, Russia, Germany, France, Japan and China is all being used quartz lamp radiant type Aerodynamic Heating environmental simulation test technology as important ground level heat research technique.
In the time that hypersonic aircraft High Mach number flies, casing surface temperature is very high, and density of heat flow rate is very large, and therefore, in the time carrying out ground level heat environmental simulation test, required instantaneous overall heating power is very huge.The power of the quartz lamp heating tube of for example single 30 centimeter length can be up to 7000W, when work, the amperage of electric current is very large, during for guarantee test, large electric current passes through, avoid conductive component loose contact and occur that arcing burns out the phenomenon of electrode, the reliable power supply connecting mode of quartz lamp radiant heat source electrode is very important.Prior art is to adopt the mode being tightened by bolts that makes shown in Fig. 1 that high-power quartz lamp radiant heat source electrode and conductive seat are connected firmly, with the reliability of guaranteeing that high-power quartz lamp radiant heat source electrode conducts electricity when the heat test.But, because quartz lamp heating tube electrode is wrapped by thin-walled quartz glass, very fragile, be subject to very easily damaging after external force, the thermal coefficient of expansion of copper quartz lamp heating tube electrode is larger in addition, add the impact of the factors such as very long quartz lamp axial deformation at high temperature, if adopt existing fixed electrode bearing technology, very easily cause after connecting firmly by force, the damage of fragile quartz lamp heating tube, the vacuum sealing that destroys quartz lamp burns quartz lamp, causes the non-uniform phenomenon in temperature field, affects the reliability of result of the test.
The utility model designs a kind of Aerodynamic Heating and tests high-power quartz lamp radiant heat source electrode elastic coupling arrangement for this reason.Make it can ensure in test reliably passing through of large electric current, can make again quartz lamp radiant heat source electrode do not forced completely to connect firmly, in the time carrying out high temperature heat test, produce axial deformation in copper quartz lamp radiant heat source electrode expansion elongation and very long quartz lamp heating tube, can under "on" position, allow to produce suitable relative displacement between quartz lamp radiant heat source electrode and electrode connecting rack, make fragile quartz lamp heating tube electrode do not forced fixing and damage in reason two ends, for the development of high-speed missile and high-speed aircraft aerospace vehicle provides safe and reliable high thermal environment research technique.Therefore, this Aerodynamic Heating is tested high-power quartz lamp radiant heat source electrode elastic coupling arrangement and is had important military engineering using value.
