Flight platform

The flight (experimental) platform of the UAS test site is a software and hardware complex that provides all types of UAS flight tests. The UAV, as a test object, has different levels of technical maturity, reliability and safety at different stages of its life cycle. Therefore, the flight platform is designed to provide flight tests throughout the entire UAV development process (from the technology demonstrator to the prototype subject to certification).

 

The flight platform is designed to automate the functions of the UAS test site officials / personnel during UAS flights planning and maintenance at various flight mission stages. It provides a solution to the problems of conducting full-scale UAV flight experiments based on automatic reception, processing and display of information received from surveillance sensors and other sources of information.

The flight platform provides:

  • observation of air and ground situation as well as experimental UAVs surveillance using technologically independent means of cooperative and non-cooperative surveillance, on-board and ground based

  • measurement of UAV kinematic parameters and characteristics, their registration, processing, documentation and reproduction of data

  • ensuring the safety of UAV flight tests by implementing algorithms for assessing the ground, air and meteorological conditions, predicting the conditions for safely maintaining parameters to ensure UAV stability and manageability, generating and issuing early warning information about potential conflict situations, the threat of a UAV collision with other objects in the air and on the ground, a collision with the ground, obstacles, getting UAVs into dangerous weather conditions, preventing the UAV from reaching critical angles of attack

  • formation of a unified information and control field for participants of flight and ground tests (control group, UAS ground crew, observation posts, flying laboratories, calculations of test support facilities)

  • automation of UAV flight tasks development taking into account the ground and air conditions and test tasks when interacting with the UAS test site digital platform

  • management of the UAS test site facilities and test units on the ground and in the air during the preparation and conduct of flight experiments

  • providing visualization of the ground and air situation at the workstations of the flight experiment control group officials and at the collective use display facilities

  • assessment of the current meteorological situation and automated forecasting of its development in the flight area using data from ground and onboard facilities

The flight platform includes the following functional subsystems:

  • subsystem for monitoring air and ground conditions

  • subsystem for measuring UAS parameters

  • subsystem for monitoring and preventing threats of UAV collision with air and ground objects, falling into adverse weather conditions, etc.

  • ground and air communication subsystem

  • flight experiment planning subsystem

  • test site management subsystem

The flight platform technical and hardware components include:

  • radar station for detecting small-sized UAVs in the near zone

  • ground-based meteorological support facilities

  • video surveillance system for UAV flights

  • UAS with flying UAV laboratory and support aircraft equipment

  • complex of UAV surveillance, control and flight control facilities

  • automated workplace for displaying and managing three-dimensional information

  • trajectory measurement tools based on navigation satellite systems

  • aircraft noise measurement equipment

  • vibration measurement equipment

  • equipment for measuring the atmosphere meteorological parameters from an unmanned aircraft

  • mobile UAV flight control point

UAV functional state parameters measurement

The measurement subsystem allows to measure kinematic parameters of the UAV movement (trajectory measurements), structural vibrations and aircraft noise. In addition to performing measurements, it will ensure rapid assessment of the material quality, its processing, documentation and reproduction.

Flight experiment planning and management (based on VIRTUOSO workstation)

Planning:

  • flight experiment execution planning (route and profile) together with the Digital platform

  • optimized test flights arrangement in the plan table

  • automation of flight task development process

  • visualization of UAV flight task development and functional capabilities of flight support tools on special workstations and collective use tools

Management:

  • UAV pilot compliance with the flight experiment conditions (quality control of standard maneuvers and operations)

  • quick piloting quality adjusting during the flight experiment meaning rapid command or information transmission to the UAV pilot if flight task conditions are not strictly observed in order to prevent flight experiment from repeating

  • current monitoring of flight safety conditions and rapid commands transmission to the UAV pilot in order to prevent the occurrence of critical situations or unintentional excess of flight/operational restrictions

  • operational and quantitative analysis of incoming information to assess the quality and validity of the experiment

Traffic participants monitoring

  • dependent cooperative surveillance (with ADS-B transponders, 1090 ES standard)

  • independent cooperative surveillance

  • non-cooperative radar surveillance (with multiposition radar system POLINOM)

  • visual surveillance (with remote video surveillance system certified by IAC and Federal Agency for Air Transport)

         - observation of near-field airspace (360° vision range from optical sensors)

         - detection and tracking of tested UAVs in automatic mode

  • surveillance from flying laboratory

Flight safety monitoring and accidents prevention

The security of UAV ground and air traffic will be provided by the monitoring, control and management complex (based on A-SMGCS system modernization with VIRTUOSO system) which ensures:

  • operational provision of observation information to the flight management team

  • formation of early warnings about potential conflict situations and threats of UAV collision with other objects in the air and on the ground, collision with the ground, obstacles, warnings about dangerous weather conditions

  • control of deviations from the route and the specified flight path

Flight experiments meteorological support

(with AWOS, MET RADAR and PULSE DOPPLER WIND LIDAR SYSTEM)

  • measurement of surface atmospheric parameters (temperature, pressure, humidity, speed and wind direction), visibility and height of lower border of cloudiness

  • detection of dangerous weather phenomena, areas of precipitation and forecast of their movements within a 100km radius

  • measurement of temperature profile in the atmospheric surface layer

  • monitoring of wind conditions in the airfield area at ranges of up to 5000m with automatic identification of hazardous wind phenomena

  • access to the space weather data

  • access to the extended weather forecast
