  In addition, in Japanese Patent Laid-Open No. 2000-172883 “Fluid Simulation Device”, in a fluid simulation device that flows around an object, it is possible to create a lattice by improving the recognition function of the object shape and the determination function of the fluid region and the non-fluid region in the calculation region. An apparatus that shortens the time and improves the efficiency of fluid behavior analysis has been proposed.

By the way, in designing flying objects that fly in the air such as aircraft, moving objects that are not in the air but move in the atmosphere such as land and water, model airplanes, all kinds of flying objects such as exercise equipment, and moving objects Needs to be calculated in consideration of air resistance and lift.
In addition, even if the design is based on aerodynamics, fluid dynamics, etc., the turbulence of the air flow can be reduced or cannot be eliminated. Even so, it is affected by the flow of air due to flight / flying speed, acceleration, flight / flying direction and changes, and weather conditions.

Japanese Patent No. 2990273

On the other hand, a technique using ultrasonic waves has been proposed for manipulating minute objects in a fluid medium. When an ultrasonic wave traveling in the fluid is blocked by an object, a force appears that pushes the object in the direction of the sound, and this force is called acoustic radiation pressure, and it is possible to apply a force to the object without contact. Is. Although this force is weak, it is possible to concentrate the force on a minute region by focusing an ultrasonic wave or generating a standing wave.
In Japanese Patent No. 2990273, “Ultrasonic non-contact micro-manipulation method and apparatus using multiple sound sources”, a micro object in a medium is captured in a non-contact manner using a plurality of ultrasonic waves, and moved two-dimensionally or three-dimensionally. A method and apparatus have been proposed.

In addition, the technology that promotes the mixing reaction in the turbulent flow field using ultrasonic waves is very promising, and the reason that the ultrasonic wave promotes the reaction is that the shear force is mainly used for mixing on a large scale. Compared to promoting, ultrasound is said to be capable of promoting mixing on a small scale.

Since the wind speed data and direction data of the air flow fluctuate depending on the flight direction, flight speed, weather conditions, etc. of the flying object, it is always sensed by the sensor and transmitted in almost real time. It is desirable to perform operations.

It is desirable to store various types of design template data that is the basis of design according to the design application of various flying objects. For example, the user can create customized design data by selecting specific template data from the template data of an aircraft model and inputting conditions and preferences.
In addition, when designing by accessing a server from a user terminal via a network and starting a program stored in the server, it is customized by selecting and specifying a desired price, desired performance, etc. (S102). It is also possible to use such a method that the design data is output and, for example, a model or other flying object is ordered based on the completed design data.

Based on the input by the design information input means, and the input design information (design condition data), template data, etc., the flying object design means (CAD program) is designed to design the flying object designed (design data). Is output on the screen (S103).

It is desirable that the turbulent flow analysis means analyzes turbulent flow information corresponding to a plurality of different moving directions or different moving speeds of the flying object by inputting a plurality of moving object movement information. This is because, for example, the location and range of the turbulent flow change according to changes in the direction of flight and changes in speed.
The turbulent flow analyzing means analyzes at least one of the direction, speed, and range of turbulent flow, so that the ultrasonic wave generating / analyzing means described later analyzes at least one of the direction, speed, and range of ultrasonic irradiation. Can do.

When determining the necessary range of ultrasonic irradiation, turbulent flow information corresponding to different moving directions or different moving speeds of flying objects can be obtained by inputting a plurality of moving object movement information.

In order to irradiate ultrasonic waves from the ultrasonic wave generating means with respect to the necessary range of ultrasonic irradiation determined above, the necessary range of ultrasonic irradiation is in the air, and also the ultrasonic irradiation is skipped. Since it is affected by the movement of the moving object, it is analyzed from which arrangement location on the surface of the flying object it is necessary to irradiate (S108).
