Abstract

Povećanjem brzina kretanja zrakoplova manifestiraju se pojave koje itekako imaju utjecaj na letne karakteristike zrakoplova. Stlačivost zraka se više ne zanemaruje prilikom izračuna. Pojave poput udarnih valova, odvajanje strujnica, zračnog zida, vibracija itd. se počinju javljati u područjima okozvučnog strujanja. Kako bi zrakoplovi postizali što bolje performanse na tim brzinama i brzinama većima od brzine zvuka, kontinuirano se radi na poboljšanju aeroprofila i ostali aerodinamičkih površina. Poznavanje tih pojava je također vrlo bitan čimbenik u osiguravanju tih performansi.

Abstract (english)

By increasing the speed of the aircraft, phenomena are manifested that have a significant impact on the flight characteristics of the aircraft. Air compressibility is no longer neglected in the calculation. Phenomena such as shock waves, separation of currents, sound barrier, vibrations, etc. begin to occur in areas of transonic flow. In order to achieve the best possible performance at these speeds and speeds higher than the speed of sound, continuous work is being done to improve aerofoils and other aerodynamic surfaces. Knowledge of these phenomena is also a very important factor in ensuring these performances.
