Project summary

Among actual problems of aviation significant place have two ones given below.

1. Creation of aviation without aerodromes for aircraft with vertical takeoff and landing.

2. Development of dual sphere aircraft the movement trajectory of which lies in two physical spheres – air and water (atmosphere and Hydrosphere).

Let’s consider each problem separately.

One of the significant ways of raising efficiency of the aircraft is the reduction or full elimination of expenses for designing, construction and exploitation of airports, i.e. using aircraft with vertical takeoff and landing the basing areas of which are commensurable with sizes of the aircraft. This will give the possibility to ship cargos practically to the destination and work from unequipped areas that is very significant in extreme situations, for example, natural disasters and not to occupy large areas mainly useful for agriculture for airports near towns.

The aircraft of aviation without aerodromes/helicopter, airplane with vertical takeoff and landing (AVTL) have limited bounds of use. The helicopter that successfully carries out vertical takeoff and landing concedes to the plane in speed, effectiveness and payload capacity. It is clear that the full solution to the problem of aviation without aerodromes is in creation of AVTL equally effective during takeoff-landing and cruise flight with corresponding speed, effectiveness and payload capacity. The successful solution to this problem is connected with overcoming of a number of difficulties.

At the present time there have been designed, constructed and tested more than 50 types of AVTL and ASTL in the world. However, none of them can compete with helicopters and airplanes. Therefore, one of the most significant problems is creation of AVTL effective for transportation of loads and passengers to short and medium distances.

Let’s consider the second problem

Together with exploration of troposphere, stratosphere and space aviation and space technologies naturally find new sphere of application – hydrosphere. The synthesis of aerodynamic aircraft that move in water environment is one of the directions of development of new type of flying technology – dual sphere aircraft not depending on consequence of movement and their activities of being in either spheres. The manned dual sphere aircraft have not been created yet. At the present time unmanned dual sphere aircraft in a view of anti-submarine and anti-marine rockets of navies of different countries. The dual sphere aircraft can find their use in various spheres of peaceful activities, for example, in oceanography, town planning, hydrogeological researches, fishing, extraction and processing of raw materials directly in hydrosphere, combination transport, emergency and rescuing works, etc.

From the above-mentioned it follows that the problem of creation of dual sphere aircraft can be considered unsettled.

Practically we have two independent problems: flights and navigation each of which is extremely complicated.

The optimal solution to both problems would be creation of dual sphere aircraft with vertical takeoff and landing having also the capability of underwater motion. The technical solution to this problem is described in the Patent of Georgia GE P 19991979 B of December 5, 1999 for invention “Vehicle for flights and navigation with the method for its movement and control mechanism for inclination of wing under angle”, an international application for this invention is registered in 100 countries. The author of this patent is G.Kvaratskhelia, the Manager of this Project.

In the proposed project the solution only to the problem of creation of the aircraft with vertical takeoff and landing is designed. After completion of the work on the Project a question of creation of the dual sphere aircraft with vertical takeoff and landing can be set.

The objective of this Project is the research and development of the aircraft with vertical takeoff and landing. The technical solution will be based in the above-mentioned Patent of Georgia taking into account world achievements of various scientific schools in this field.

To objectives and tasks of the ISTC corresponds the busy condition of the scientists and specialists connected with weapon, their reorientation to peaceful activities.

The scientists and specialists of the GTU engaged in the Project have an experience in the science, research and works on the Project topic. Therefore, the competence of these scientists and specialists correspond to the level of the set tasks in the Project.

The role of Foreign Collaborator will be in provision of the newest information on the Project topic, discussion of tactics and technical requirements, technical tasks, methods of research and designing, results of the work on creation of the aircraft and its tests. Besides that the role of the Collaborator will be in rendering the assistance in provision of material support to the Project team members in visits to International meetings.

Expected results have scientific, practical and commercial meaning. As a result of the Project implementation a non-traditional aircraft with vertical takeoff and landing will be created that will be capable to carry out the economically valid, competitive transportation of passengers and loads to short and medium distances with subsonic speeds of flight.

The scope of activities includes: scientific researches in aerodynamics, flight dynamics, aeroelasicity, technological designs of the aircraft. The significant element of the designing works will be the weight designing, optimization of the designing-power scheme, arrangement and centering. During the development of technological scheme of fabrication and assembling of the aircraft various modern physical and technical methods of processing will be considered and the following principles will be used: paneling, sectioning, unitization, selection of designing materials with high specific stability, optimization of selection of the novelty coefficient and use of materials. In the Patent GE P 1999 1979 B of July 30, 1999 (Author: Kvaratskhelia) an original control system of the aircraft is described that will be used during fabrication of the working models.

A stand for unmanned tests of working models will be created. These are the technical approach and methodology.
