PREAMBLE

Year after year we can see the increasing amount of aircrafts with electrical powerplant (AEPs). Beginning from small aircrafts, now this family include the crafts from several grams to tons, from several centimeters to hundred meters, from minutes of flight time to months of flight time, from meters above the Earth till tens of kilometers... Now appear piloted electrical airplanes that in several years can compete with “traditional” small airplanes.

The same words we can say for Unmanned Air Vehicles (UAVs). One can see the growth of UAVs types amount and total amount of UAVs. They compete with piloted aviation in flight time, altitude, ability to fly in dangerous conditions including chemical and nuclear hazard zones.

The most part of AEPs are UAVs. AEPs also use technologies from the aircrafts with another type of powerplants. From this point of view it is important to analyze the advantages and disadvantages of this aircrafts together, to focus on common problems but keep in mind peculiarities of each type of craft.

The main disadvantage of AEPs now is low value of energy density (ED) of energy storage (accumulators etc.). One of the ways of ED increasing is the usage of fuel cells. The aircraft with fuel cell is, on the one hand, an electrical aircraft. On the other hand it has some peculiarities of aircraft with fuel (for example, its mass changes during the flight, it might require the ambient air for the chemical reaction).

As the energy density of accumulators is not high enough there are at least two ways of AEP performance increasing. One of them is to search for more “energetic” accumulators and improve the existing technologies. Another way is to use optimal flight regimes including, may be, the unsteady ones.

One of advantages of AEPs is the ability of miniaturization. But all the systems of AEP must be miniaturized. One of them is electronic devices, especially autopilot system. So, the tendencies of electronics miniaturization must be taken into account.

Small aircraft can fly in “non-traditional” places and conditions, for example in town. These conditions assume not only the complex lay of land but also complex wind and vortices pattern.

The idea of this Workshop is to make the meeting of scientists and specialists working in the field of electrical (unmanned and manned) aircraft, to exchange ideas in this topic, to discuss joint efforts etc.

The organizers of this Workshop are Moscow Institute of Physics and Technology (MIPT) and International Science & Technology Center (ISTC). Also among the sponsors and co-organizers are Central AeroHydrodynamical Institute (TsAGI), Japan Aerospace Exploration Agency (JAXA), Russian Foundation for Basic Research (RFBR).

The main ideas of this workshop are to analyze and understand the peculiarities of UAVs and AEPs, to define the ways of progress and technologies required for these types of aircraft.
