The same monotonous operation of measuring the distribution of atmospheric parameters is performed every day, four times a day, in most countries of the world. Expendable uncontrolled balloon probes are used. This procedure is very expensive if the cost of the probe is $200-$250, plus the amount spent on payments for work and equipment (usually around the same price).
Moreover, the presence of such a number of unguided aircrafts within both the transport and passenger aviation flight levels is a rather serious threat -- especially where air traffic is intense. Consequently, accidents in the air (due to air traffic congestion) are unfortunately not something new. For instance, in 1970, 45 people died when an AN-24B (board number 47751) collided with a ball-probe. Similarly, in 2017, there was a collision of a Boeing 757-200 (Delta Airlines' Flight 8935) with an unknown object.
ABOUT
AEROLOGICAL RESEARCH DRONE
Aerological Research Drone with X-Wing
We propose to replace uncontrolled and bulky balloons with compact, intelligent aircrafts. The use of unmanned systems will not only reduce such risks significantly, but will also greatly improve aerological observation technology.

UAVs are non-expendable; further, due to the variety of their configurations, their research costs are decreasing at times. Next, their use has become much more operational –- for instance, their flight time lasts no more than half an hour. In addition, UAV measurements are more accurate since the equipment can start working and analyzing the situation from the moment of take-off until the moment of its landing.
There is still much space for improvement and innovation when processing clouds. At present, mostly meteorological rockets (for example, "Alazan") or specially re-equipped civilian aircrafts are used to conduct such studies. Nevertheless, both methods are not precise/effective enough, as well as are extremely expensive to use.
CLOUD INSPECTION
The implementation of unmanned aerial vehicles is capable of producing a technological revolution. Further, our machines possess the capability of flying directly into a cloud, using the trajectory determined "on the fly" from the ground at a constant flight level (i.e., Alt Hold flight mode). This new technology greatly improves the accuracy, as well as efficiency, of both meteorological work and research; most importantly, it reduces their cost.
X-Wing
Tailless Airplane

We suggest using such layout variants as a tailless airplane and / or an X-wing airplane with silver-iodide aerosol cartridges placed on their external mount, when carrying out these operations.

Airplane with an X-wing
(analogues – the MAI airplane with an X-wing and the Shkval-1A project airplane of the Sukhov Design Bureau, barring the HERO-400EC ammunition) is intended for vertical take-off, landing and hovering in two modes – vertical ("helicopter") and horizontal ("airplane"). It is characterized by low inductive resistance, high power-to-weight and thrust-to-weight ratios (up to 2-3), good controllability over all three spatial axes. Due to the large critical angle of attack, it is not very sensitive to ascending and descending flows, which allows it to fly in conditions of large-scale turbulence, for example, directly near mountain slopes or in cumulus clouds. The presence of four wing consoles allows it to fly at altitudes of more than 32 808 ft.

It is designed for flights in conditions of strong turbulence, with strong ascending and descending currents in mountains at altitudes of more than 14 763 ft. It is able to fully operate where piloted aircrafts and traditional unmanned aerial vehicles are helpless.

This configuration (layout) is distinguished by: high values of critical angles of attack, symmetry of aerodynamic characteristics along all axes, good controllability, ability to carry out vertical take-off and landing.

The main purpose is air support of search and rescue operations in the mountainous terrain at high altitudes.

Special feature of the instrument compartment is the Flir Boson thermal imager.

The placement of additional payload (containers for medicines capable of removing oxygen starvation or for small loads) and/or parachute is provided for on the external mount.

Tailless airplane
is one of the main types of small unmanned aircrafts intended for aerial photography and monitoring the earth's surface (analogues – Horten Ho IX (1940), Northrop N-1M (1940), B-49 (1946), Northrop B-2 Spirit (1989), unmanned aircrafts of Geoscans and ZALA companies). It differs in simplicity of design, small specific wing load, and difficulty of manual control.

The main purpose – monitoring the earth surface, aerial photography, creation of three-dimensional image, cartography, search operations at a distance (height) of at least 656 ft from the surface of the earth (slopes), etc.

Features of the instrument compartment – higher resolution camera with the between-lens shutter, thermal imager

External mount can be used for extra payload – additional accumulators, radiation environment and harmful atmospheric admixtures monitoring sensor, and / or a parachute

It is designed for flights in a relatively calm atmosphere at altitudes of up to four thousand meters.

Features of design and configuration (in comparison with the X-wing airplane):
  • reduced value of the wing specific load;
  • increased weight of the permitted payload;
  • reduced number of drive motors – reduced energy consumption and increased flight time and range;
  • simplicity of construction.

A huge variety of tasks and functions for our aircrafts dictate the need for a wide variety of assembling options for the central component of the machine: its instrument compartment. Just like the exterior of our aircrafts, the inner configuration can be directly modified during flight preparations.

As a matter of convenience, we have combined all options for equipping the instrument compartment within two groups: constant filling (i.e., it does not change when the aerodynamic configuration of the aircraft and / or the flight assignments are changed) and variable payload (i.e., it remains contingent upon the user's preference; in addition, it is dependent upon the specific flight objectives).
