W artykule przedstawiono wyniki prac analitycznych realizowanych w Instytucie Technicznym Wojsk Lotniczych w zakresie możliwości prowadzenia i analizy komunikacji werbalnej pilota w kabinie wielozadaniowego samolotu wojskowego, w warunkach oddziaływania na niego dużych przeciążeń liniowych występujących podczas wykonywania manewrów. Omówiono wybrane pokładowe systemy komunikacji werbalnej i rejestracji mowy pilota stosowane na statkach powietrznych eksploatowanych w Siłach Zbrojnych RP. Szczególną uwagę zwrócono na problemy badawcze związane z budową zintegrowanych systemów awionicznych, werbalnie wspomagających pracę pilota i rejestrujących jego mowę oraz omówiono specjalistyczne metody badawcze wykorzystywane do fonoskopijnych badań mowy i nieartykułowanych parametrów głosu, a także innych dźwięków pochodzących z kabiny statku powietrznego (tzw. tło akustyczne). Zaprezentowano przykładowe zapisy i wyniki analizy korespondencji werbalnej pilota oraz przedstawiono zakres zastosowania tych wyników w przyszłych pracach badawczych (m.in. w warunkach oddziaływania dużych przeciążeń liniowych wytwarzanych na wirówce przeciążeniowej).

The paper presents the results of analytical works implemented in the Air Force Institute of Technology in terms of the possibilities of conducting and analysing the pilot’s verbal communication in the multi-purpose aircraft cockpit, under conditions of influence of large linear loads, which occur during the performance of manoeuvres. The selected on-board verbal communication and the pilot’s speech recording systems used in the aircraft operated in the Polish Armed Forces were discussed. Particular attention was paid to the research problems related to the construction of integrated avionics systems, which verbally support the pilot’s work and record his speech, but also to the methods used in the speech phonoscopic examination and inarticulate voice parameters, as well as other sounds coming from the aircraft cockpit (the so-called background noise) were presented. Sample records and analysis results of the pilot’s verbal correspondence quality under conditions of influence of large linear loads, in addition, the scope of using these results in future research works (on the high-G training) were presented.

The problem of optimal thrust and path angle control is considered in the paper for given trajectory trajectories in the vertical plane when specific energy or altitude derivative with respect to time is not equal to zero. The minimized functional is assumed to be a fuel consumption. The range and endurance may be arbitrary or given. The path angle is not considered as a small value irrespective of using the energy approach. The problem is solved by means of the maximum principle. As a result the adaptive extreme control laws for aircraft thrust or path angle that provide the minimum fuel consumption have been obtained. These control laws have the form of ordinary differential equations. They may be used in simplification of some optimization problems and for the on-board implementation as regulators. The paper presents the results of calculations made for comparison of effectiveness of the proposed adaptive extreme control laws with the optimal solutions obtained from a sufficiently precise second order method. A difference in the relative fuel consumption is of an order of 0.02 -2 % for different examples.

The paper presents aerodynamic and dynamic characteristics of the last version of IRYDA-22 M96 Polish trainer/combat aircraft against a background of other modem combat aircraft. It is noted that the lryda-M96 has performed initial flight tests, during which it could make spatial manoeuvres at high angles of attack beyond the stall.

The process of designing has two parts: the function to be performed by the aircraft and the optimising process whereby an initial design is improved to satisfy a wide range of requirements, both technical and economic. The first part draws on my 60 years experience(1) of aerospace design from which I have learnt how to deal with the initial ignorance at the start of a new project. The next section describes some new technology and configurations likely to mature for civil and military aircraft. Then I suggest some hitherto untried applications of aeronautics such as re-vegetation of arid regions, third world transport and maritime air vehicles. Finally, and considering the later part of next century. I venture into some revolutionary propulsion concepts that could dramatically change aeronautics.
