Description

1 - Vertical wind tunnel with flow resonant absorber cabin

A vertical wind tunnel having a flow based resonance absorber cabin FULL DESCRIPTION BACKGROUND The invention relates to cavity resonance absorption incident by left parallel openings of the flow in media where there is a high velocity air flow. The invention relates in particular to a vibration cabin placed at the entrance door to absorb the cavity resonance 0 (oscillation; oscillation; space vibration) formed as a result of the flow separation formed at the door; Which was found to enter the field flying in the vertical wind tunnels used for paragliding training. Previous art It is known that vertical wind tunnels are found in previous art; Which is used as a simulated paratrooper training to train paratroopers. Vertical wind tunnels are formed from air ducts with air flow in a vertical direction. The vertical wind tunnel includes a flight space for the person to be trained in free-fall flight, and the pilot in this field of flight gains simulated free-fall experience. The airflow carrying the pilot is provided through a duct through propellers placed in the wind tunnel. The waiting trainee is taken into the waiting room; which has a hatch door for the flight field; To the flight field after all controls are completed. There are prior art patent applications related to vertical wind tunnels. Japanese Patent No. 0 JB 5779759460 (109327540) and International Patent No. WO (WO2007008184) 0010001 64 can be given as examples of vertical wind ducts. Vertical wind tunnels can be used for special practices such as paragliding or skydiving; It can also be designed for general use for the purpose of entertainment.

71 - in vertical wind tunnels; It was found that preventing the separation of the flow formed at the door to enter the flight field and preventing the cavity resonance formed as a result of this was very important. As an example of solutions on this topic; International Patent Application No. WO 70070177459 (1702006012647). The forms of the patent application relate to the solutions contained in the form of; and Figure 5. In the application indicated in the said patent; An attempt is made to prevent cavity resonance by at least one forward/modified front facing positioned at the door entrance opening to the flight area. however; This solution does not have enough effect at low air speeds and also the size of the waiting area should be smaller in this solution. in addition to; The effect of the pressure formed by the vertical movements performed by the trained persons inside the tunnel at the entrance door area during parachute training may not be prevented on the walls of the waiting area. Prior art 0 applications related to cavity oa absorption cannot provide the required efficiency. The number of AB can be increased about applications related to the cavity resonance absorption formed as a result of the induced flow separation at the door that exists to enter the flight field in vertical wind tunnels; But all descriptions in prior art documents are ineffective and insufficient. When analyzing the improvements in prior art and patent applications cleo the existence of the need for a vibration cabin 0 a cavity resonance absorption component as a result of the component flow separation at the door that exists to enter the Jin flight in vertical wind tunnels has necessitated the inadequacy of the previous solutions Improvement in related technical field. GENERAL DESCRIPTION OF THE INVENTION The present invention relates to a lung aspiration cabin based on flow at surface openings which meets 00 requirements mentioned above, removes all obstructions and brings some additional advantages. From the condition known as annihilation, the purpose of the invention is to eliminate vibration problems created by cavity resonance in the entire interval from the initial velocity up to the flight velocity of the system.

- fa. Another purpose of the invention is to have a wider parking area. especially; enough space is created on Bale time for military equipment that requires more space and the number of personnel can be increased; Which affects due to the presence of a larger area. In this way; The number of workers in the required groups (cals) can be increased to be trained. In particular; The purpose of the invention is to make the air pressure formed by the vertical movements © performed by the trained persons without any effect on the waiting room. In order to achieve the aforementioned purposes; The invention represents a vertical wind tunnel comprising air flow ducts having a rectangular structure. High power fan mechanisms to provide airflow within these air ducts; The flight field holds at least one person in the air; It is required to be trained within at least one airflow duct »waiting area for persons waiting for the purpose of training» and a waiting room in 0 flight» and includes a vibration cabin; which is positioned as a Jia device passing from the waiting area to the suction of the lungs in the area in which the flight field and the waiting area is located and in such a way that it corresponds to the aperture used to pass from the waiting room to the flight field; which has a closed volume; which includes insulators and at least one absorbent device placed in the lower and lateral parts; At the surfaces of contact with the ground and the walls of the flight field in order to provide absorption of the energy formed by confining the resonance 0 cavity formed as a result of the separation of the air flow caused in the internal volume through the hole in the flight field., in order to achieve the previously mentioned purposes ; The invention is a vibrating cabin placed behind the relatively large hole on a surface to provide suction for the lung of the cavity formed as a result of the fluid flow of this surface paralleling the hole on this surface; and the wide volume behind this opening; 0 is characterized by this; it includes at least one absorbing device; It absorbs energy through the resistance formed by the insulators placed on its bottom and side surfaces and by the adjustable non-return valves placed at the air inlet and outlet ports.
