However, for example, doubling cruising speed of flight increases its average ground speed only 10-15%. This is because a lot of time spent on such regimes as takeoff, landing, maneuvering on the ground, and so on. Since the bulk of air traffic is carried away from the 300 to 1000 km, take off and landing can be up to 50% of the length of the flight. So one of the ways to solve pressing tasks outlined is to build an aircraft that combines quality, speed horizontal flight aircraft and helicopters take off and landing. For the first time the technique of calculating aerodynamic characteristics of the aircraft vertical takeoff and landing small size for rational choice of its parameters in order to achieve the required performance testing. We consider a model airplane with rotary screws at the ends of the wings. This combination provides the benefits of a helicopter, namely the possibility of vertical takeoff and landing and hovering at a certain height in the air, with the benefits of the plane - much greater speed and flight range. The main problem of this aircraft is to ensure the stability and controllability during mode transition from vertical to horizontal flight and vice versa. To determine the required parameters propulsion Comparative calculations generated by aircraft with different layout schemes. Research of mass characteristics to determine the advantages and disadvantages of each scheme. The materials performed the study, the results of calculations of aerodynamic characteristics of the designed aircraft vertical takeoff and landing at different tilt angles of attack and thrust vector and at a speed of zero to switch to horizontal flight.ΠŸΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Ρ‹ Π½Π΅ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Π΅ аспСкты расчСта аэродинамичСских характСристик Π»Π΅Ρ‚Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ Π°ΠΏΠΏΠ°Ρ€Π°Ρ‚Π° с ΠΏΠΎΠ²ΠΎΡ€ΠΎΡ‚Π½Ρ‹ΠΌΠΈ Π²ΠΈΠ½Ρ‚Π°ΠΌΠΈ Π½Π° ΠΊΠΎΠ½Ρ†Π°Ρ… ΠΊΡ€Ρ‹Π»Π°.

One of the main features is that it occurs during the measurement processing the three-dimensional coordinates of points, whereas during the normal rigging check - the distance between the projections of the points on the vertical or horizontal plane. Introduced a three-dimensional cartesian coordinate system relative to which measurements are performed. Proposed a method of carrying out a "mathematical alignment", which first calculates the parameters of the airplane coordinate system in the transition from a system of coordinates in which the measurements were made, and then recalculate the coordinates of the measured points in a new coordinate system. This allows to avoid the need for ascertaining the aircraft in a horizontal position. The paper analyzes the new possibilities of deformation analysis of surfaces with quick measurement of a large number of points on the unit’s surface, which is generated on the basis of a new object actual geometry electronic model for aerodynamic researches.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдставлСны основныС возмоТности ΠΈ прСимущСства нивСлирования с использованиСм Π»Π°Π·Π΅Ρ€Π½Ρ‹Ρ… ΠΊΠΎΠΎΡ€Π΄ΠΈΠ½Π°Ρ‚Π½ΠΎ-ΠΈΠ·ΠΌΠ΅Ρ€ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… систСм.

These data include information on the theoretical external surfaces of the airplane, the location of such elements of its design-force elements as spars, ribs and stringers of wing, etc. The basic geometry is the foundation for subsequent automated design of airplane and also for creation technological processes of its manufacture and use. New ways and methods of integrated forming in the environment of modern CAD systems have been proposed. They are based on extensive use of information technology databases, flexible performing alternative calculations and the correct implementation of the geometric modeling of technical objects in the environment of modern computer-aided design. OpenOffice Calc spreadsheets and CAD SolidWorks were taken to carry out related research. Database of aerodynamic profiles and basic geometry of the wing was set up in the environment of the first software package. Automated communication geometric wing database with other software for its design has been installed. The corresponding geometric relationship database wing and SolidWorks CAD has been implemented. This technique allows an automated way to create and analyze multiple design variants of the airplane wing. The specified method significantly improves the quality of created technical objects. The laboriousness of design work is also reduced. This is achieved by through automation of all design operations. Illustrative examples in the environment OpenOffice Calc spreadsheets and SoidWorks CAD are given in this article. Calculation formulas to populate of database fields are shown. Questions relationship base geometry of the wing and its strength, design, technology, manufacturing and operation are analyzed. The proposed technique can be used as part of the general methodology of complex automation of the aircraft throughout its life cycle. Summary of the practical implementation of the results and their use in further research in the field of computer design of airplane has been completed.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ ΠΏΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Ρ‹ Π½Π΅ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Π΅ аспСкты Π²Π°Ρ€ΠΈΠ°Π½Ρ‚Π½ΠΎΠ³ΠΎ модСлирования Π±Π°Π·ΠΎΠ²ΠΎΠΉ Π³Π΅ΠΎΠΌΠ΅Ρ‚Ρ€ΠΈΠΈ ΠΊΡ€Ρ‹Π»Π° самолСта.

Complications constructive power circuits aircraft and growth requirements for the quality of their design has led to the application of the finite element method. This method allows to accurately model complex structures, to determine the stress-strain state and to automate the processes of synthesis in selecting schemes, but because of the great complexity and duration of the set-up cycle before widely used only in the later stages of the design During formation of certainly-element models of construction arises to reduce design time. The most effective issues of these questions are addressed using automated technologies. For successful implementation of the latest needed algorithms for solving the tasks on which developed appropriate methods and means of simulation. The choice of algorithm is part of the design process, as design problems belong to a class of inverse problems. For this reason, a list of the algorithms can not be determined in advance. As a result, it is necessary to select and connect directly to the algorithms in the solution of the problem (dynamic link algorithms). The purpose of this paper is to develop an automated algorithm forming the structure of the finite element model of the power of frame fuselage. In this paper an automatic algorithm of formation of the structure certainly-element model force fuselage frame. The structure of the finite-element model is synthesized simultaneously with the creation of the appropriate subobject through its automatic activation. The parameters of this structure must be passed on to the class object fuselage for the synthesis of the finite-element model. In the design process by KCC considered algorithm, the user can create the required number of settlement CEM frames. The algorithm is universal, because it depends on the specific configuration of the designed construction. Therefore, it can be used in the design of aircraft frames of different classes.ΠŸΡ€ΠΈ Ρ„ΠΎΡ€ΠΌΠΈΡ€ΠΎΠ²Π°Π½ΠΈΠΈ ΠΊΠΎΠ½Π΅Ρ‡Π½ΠΎ-элСмСнтных ΠΌΠΎΠ΄Π΅Π»Π΅ΠΉ конструкции Π²ΠΎΠ·Π½ΠΈΠΊΠ°Π΅Ρ‚ Π·Π°Π΄Π°Ρ‡Π° сниТСния Π²Ρ€Π΅ΠΌΠ΅Π½ΠΈ проСктирования.

These types of problems preliminary design and the method of calculation of typical aircraft structural elements for example longitudinal force element sets as stringer. Also, the algorithm constructs a fully stringer system aided design of integrated Siemens NX. What can shorten the design time and use it as a reference for the calculation and further change just values for other dimensions stringers. Methods integrated design ensure the application of standard parametric analytical stringers in the calculation of aerodynamics and strength, life and vitality, weight of the aircraft and its alignment, safety of structures, as well as technological preparation of production and quality control, maintenance and repair. Considered aided design techniques can be extended to other than the stringers typical elements airframe.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ рассмотрСны ΠΏΠΎΠ΄Ρ…ΠΎΠ΄Ρ‹ ΠΊ ΠΈΠ½Ρ‚Π΅Π³Ρ€ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠΌΡƒ Π°Π²Ρ‚ΠΎΠΌΠ°Ρ‚ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ проСктирования.

Therefore, the development and introduction of new effective methods, techniques and algorithms for computer-aided design are relevant today. It is known that the system consisting of the optimal elements itself is not necessarily the same. Therefore, complex optimization is very important for the designed technical objects. Geometric models have a special place in integrating for computational models of technical objects because significant number of output characteristics substantially depend on geometrical parameters. The applications of structural-parametric geometric modeling methodology for design-technologic optimization of technical products are analyzed in this article. Variant engineering design was shown on the example of spar of airplane wing. Basic techniques of proposed method were presented. The emphasis was placed on their universal and invariant character for different objects and processes. Prospects for further development of this scientific field studies on the spread of its practical application to optimal designing of different industrial products were considered. The main advantages of the analyzed computer-integrated engineering and process design of industrial products based on the use of structural-parametric geometric models is the universality and invariance of the proposed techniques for different objects and processes. Featured approach provides a flexible and productive implementation of complex optimization of industrial products. This direction of creation of technical products requires further intensive research for its successful practical realization.ΠŸΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Ρ‹ вопросы эффСктивного примСнСния структурно-парамСтричСской ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠ»ΠΎΠ³ΠΈΠΈ формообразования для провСдСния комплСксной ΠΎΠΏΡ‚ΠΈΠΌΠΈΠ·Π°Ρ†ΠΈΠΈ ΠΏΡ€ΠΎΠΌΡ‹ΡˆΠ»Π΅Π½Π½ΠΎΠΉ ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ†ΠΈΠΈ.

    Metalloproteinases and their inhibitorsβ€”diagnostic and therapeutic opportunities in orthopedics

    Matrix metalloproteinases (MMPs) and related enzymes (ADAMs, ADAMTS) and their inhibitors control matrix turnover and function. Recent advances in our understanding of musculoskeletal conditions such as tendinopathy, arthritis, Dupuytren's disease, degenerative disc disease, and bone and soft tissue healing suggest that MMPs have prominant roles. Importantly, MMPs are amenable to inhibition by cheap, safe, and widely available drugs such as the tetracycline antibiotics and the bisphosphonates. This indicates that these MMP inhibitors, if proven effective for any novel indication, may be quickly brought into clinical practice
