SU728349A1 - Device for measuring deviation from the given craft landing time - Google Patents

Description

I

The invention relates to aeronautical engineering and can be applied in the design of indicator devices, for example, for DI and for the deviation from a predetermined landing time of an aircraft.

A device is known for calculating the arrival time, containing a range finder and a clock connected via a flight duration calculator with a time error calculator, the output of which is connected to the time error indicator 1.

However, the known device has a low degree of determination of deviations from a given landing time during movements of the aircraft at an uneven speed, for example, during complex weather conditions. A: The purpose of the invention is to improve the accuracy of determining deviations from. specified landing time during flight. in adverse weather conditions x.

The goal is achieved by the fact that the disorder-additionally introduced parameter set pools and. the calculator of the estimated speed, while the remote set of parameters is connected to the input of the duration of flight, the output

which through the calculator of the estimated speed is connected to the calculator of a temporary error.

The drawing shows a diagram of the proposed device.

The device contains a range finder 1, a clock 2, a flight duration calculator 3, a parameter set remote 4, a time error calculator 5, a calculated speed calculator 6 and a time error indicator 7.

The device works as follows.

When the aircraft is moving in complex mVTyo} LOV1ShH nilot on the remote 4 set of parameters enters into the calculator flight duration data on the landing time, the coordinates of the calculated points of the track sections and the flight duration on the sections of the route. The calculator 3 also receives information from the rangefinder I and hours 2, on the basis of which it determines the flight time in the sections. Comparison of the estimated value of the landing time with the specified value is made in the time error calculator 5, taking into account the calculated information about the speed of movement received from the calculator 6 of the estimated speed, but

the value of the landing time deviation from An even value is fed to the time error indicator 7, according to which the pilot takes measures to reduce this deviation to zero. Introduction to the known device of the set of parameters and the calculator of the estimated speed, included as described above, allows; to increase the accuracy of maintaining a given landing time when flying in adverse weather conditions, thereby reducing the safe interval between landing of aircraft,

What will increase the capacity of the airport i a.
