摘要： PURPOSE:To obtain a strong incoming shock wave by traveling a free piston to increase the temperature in a high pressure chamber through adiabatic compression. CONSTITUTION:A compression pipe 2 is arranged perpendicularly to a shock wave pipe 8 generating high temperature high pressure stagnation, an ultrasonic nozzle 9, and a measuring section 10 for setting a sample disposed concentrically. Free pistons 1 each compressing the gas in a high pressure chamber 13 of the shack wave pipe 8 adiabatically are operated synchronously for respective compression pipes. Consequently, the inertial forces of the free pistons 1 are canceled each other and a moving mechanism for relaxing the inertial force can be eliminated in the wind tunnel facility. This structure eliminates the need of resetting the facility for each test and the adjustment of the installing position of a model thus suppressing damage on the sensors. Troublesome aseismatic countermeasures are also eliminated for a moving body.

摘要： PURPOSE: To improve the high-speed performance of a free piston and basic performance of a shock tunnel in a piston launching apparatus for generating a high pressure gas state of helium or the like. CONSTITUTION: The piston launching apparatus is constituted of a launching pipe 2 inserted into a compression tube 1, a launching plug 5 fitted inside from behind the launching pipe 2 and supporting a rear end of an outer side face of a free piston 3 loaded in the launching pipe 2 form thereinside at a front end part, and a secondary air-storing tank 6 set in the outer periphery of a rear end of the compression tube 1 and having an opening communicating with a slot 7. The free piston 3 is loaded in the pipe 2 before launched out. The slot 7 formed in the launching pipe 2 is shut by the outer side face of the free piston 3. Since the outer side face of the free piston shutting an air jet port from the secondary air-storing tank 6 into the launching pipe 2 is reinforced by the launching plug 5, the free piston can be thinned and reduced in weight, and moreover, the total length of the free piston can be increased. Accordingly, together with the effect of the enlargement of the air jet port, the high-speed performance of the free piston 3 is improved. Further, the deformation by the compressed air or leak of the compressed air can be prevented.

摘要： PURPOSE:To prevent metallic friction between a free piston and a compression pipe by a structure wherein high pressure gas is stored in the free piston and discharged between the free piston and the compression pipe upon start of movement of the free piston to form a gas film. CONSTITUTION:When a bell crank 9c is operated remotely upon application of pressure for moving a free piston 1, each piston valve 9a is displaced to the central side of a high pressure gas storage chamber 5 to open each ejection hole 6. Consequently, high pressure gas previously filled in the chamber 5 is ejected between the wall of the compression pipe 2 and the free piston 1 through the ejection hole 6 and eventually discharged to the rear through an exhaust hole 7 and a discharge hole 8. The high pressure gas being exhausted serves as a gas film between the wall of the compression pipe 2 and the free piston 1 thus preventing metallic contact between them.

摘要： PURPOSE:To protect the facility against damage by buffering the final stage of the stroke of a free piston by means of air cushion depending on the variation in the area of gap between a buffer plug and the inner circumference of an impact wave pipe. CONSTITUTION:A bullet type buffer plug 4 having a pointed end entering an impact wave pipe 3 and a base part of substantially equal diameter to the inner diameter of the impact wave pipe 3 projects along the axis thereof on the downstream side from a free piston 1. When the free piston 1 approaches the end of a compression pipe 2, i.e., the inlet of the impact wave pipe 3, and the pointed end of the buffer plug 4 begins to enter the pipe 3, the gap between the plug 4 and the pipe 3 decreases gradually because of the bullet-like profile thereof. Consequently, the flow rate of air from the compression pipe 2 to the impact wave pipe 3 decreases abruptly and the residual air in the compression pipe 2 is subjected to significant compression. This structure provides a buffering effect equivalent to an air cushion provided between the free piston 1 and the final end of the compression pipe 2, i.e., the inlet of the impact wave pipe 3, thus preventing solid state collision against the inlet end of the impact wave pipe 3.

摘要： PURPOSE:To enhance the universality of a deicer by installing a resonance circuit consisting of a deicing coil installed in access to the aluminum skin of an aircraft and a condenser parallelly connected to this coil, and making resonant frequency of this resonance circuit alterable according to the natural frequency of the aluminum skin. CONSTITUTION:This electromagnetic impact deicer is provided with a resonance circuit consisting of a deicing coil 2 being installed in access to an outer skin 1 and a condenser 6 parallelly connected to this coil. In addition, in order to make the resonant frequency of this resonance circuit correspond to that of an airframe, a variable inductance coil 8 is inserted into the deicing coil 2 in series. In general, natural frequency at the outer skin side varies according to a spot in aircraft, but inductance of the variable inductance coil 8 is adjusted to some extent according to that, through which variations in deicing capacity by means of a mounting position of the deicer are checked. In this connection, many types of the variable inductance coil 8 are provided and they are replaced for use according to each case, thereby making them correspond to extensive ranges in application.

摘要： PURPOSE:To pour solid point depressant instead of pressurized air to make ice melt and removed so as to efficiently accomplish the detection of ice, the removal of ice and the prevention of the clog of the porous plate when ice attaches on an aircraft, while the clog of the porous plate is prevented by pressurized air inside the dry atmosphere. CONSTITUTION:Usually, pressurized air (d) is intermittently blawn off from a porous plate 1. However, when ice is formed on the porous plate 1, since the jet of pressurized air raise the inner pressure of the porous plate 1 being controlled by ice, a pressurized air valve 5 and a freezing point depressant valve 6 are switched by a valve control circuit 7 to pour freezing point depressant (c). Ice (b) is then removed a, the porous plate 1 being recovered to the normal surface. And then, the freezing point depressant valve 6 and the pressurized air valve 5 are switched again, the pressurized air being supplied intermittently. Thereby, the clog of the porous plate 1 is prevented, ice is detected by an air system for preventing the clog and lightness is accomplished without the need of providing a new detector.
