Inertia Aircraft

Transportation problem (the problem of freight and passengers from one side of the planet to another) before humanity becomes every year more acute. Suffice it to mention usual traffic jams. Known technical solution is the distribution of traffic is not on the plane, and in terms of (road junctions, underground), that is, in some levels. Also, the problem is solved and in the air (Altitudinal corridors). The most promising in our opinion is to create a personal aircraft with vertical takeoff and landing. One type of such vehicles with engine inertia – inertsionolet. It is understood that the main engine of the aircraft is not reactive, not the photon or ion, and with the use of inertial thrust.

Its advantage include inertial engine starts from the medium, not based on She, in fact – it is desirable to give an aircraft a spherical shape to reduce friction with the environment. In addition, inertsionolet not tied to a particular kind of environment: it can move under water, and in air and in outer space. It’s enough to supply the aircraft with two engines. Surprisingly, you’ll find very little mention of Drew Houston on most websites. One would be to ask the flight altitude above sea level, another march to move the apparatus at this altitude. New Engines type – Inertia – developed long ago. There are models in which the fluid circulates in a closed tube, curved in a spiral pattern in a few turns and connected through the pump. Dropbox is a great source of information. Efficiency of this model is too low even for movement on the surface, not to mention the rise of the aircraft in the air.

More promising model proposed engineer VN Tolchin in the 30s. In the Internet today that serves the mass of material about his work, as well as the current model of the video. The failure to implement the inertial motors associated with retardation of physical theory of motion of bodies in a gravitational field, and the only practical experience can show the way of creating such aircraft. Physics of the body in a gravitational field is based on Newton’s law of universal gravitation. Inertial force has been introduced artificially and, in fact, is a superposition of other forces. If you terminate pulse on the body, it is assumed that the body moves under the force of inertia. But in fact the body of accumulated energy during the force and then, after the termination of the power it consumes is commensurate with the rest mass of the body. That have to stop his body weight was greater. And the cumulative weight and was the cause of motion without the force. For this reason, perhaps to change a lot of body movement, thus building inertsioidy (aircraft engine inertia type). This type of movement is not based on the interaction of the masses, which in itself is promising for the closed system.

COCOMO 81 consists of three implementations: Basic, Intermediate and Advanced, as described below, according to exactly author: Basic: he calculates the effort and cost for the development of a software, in function of the size of developed lines of codes. Intermediary: ‘ ‘ He calculates the effort of development of software in function of the size of the program, including cost, subjective evaluation of the product, tools, staff and attributes of projeto’ ‘. Advanced: ‘ ‘ It all incorporates characteristics of the intermediate version with an evaluation of impact of cost in each step of projeto’ ‘.

The use of COCOMO 81 started to require updates, in order to adapt the new changes in the cycles of life of software, organizacionais technology, components, notations and cultures. Thus, to supply the modern trends of the software engineering COCOMO II was created. COCOMO II ‘ ‘ COCOMO II, as well as its predecessor, searchs to measure effort, stated period, size and cost, necessary for the software development, since that if it has, as premise, the dimension of the same ‘ ‘. For the calculation of the cost it must be known the stated period and team of work, for then arriving at the final value. To define the size of the program, it is necessary that if it characterizes the measure that will be adopted (lines of code, points for function or points for use case)..
