  • 10. Supersonic Aerodynamics
    Grumman Tribody Concept featured on the 1978 company calendar. The basis for this idea will be explained below. 10. Supersonic Aerodynamics 10.1 Introduction There have actually only been a few truly supersonic airplanes. This means airplanes that can cruise supersonically. Before the F-22, classic “supersonic” fighters used brute force (afterburners) and had extremely limited duration. As an example, consider the two defined supersonic missions for the F-14A: F-14A Supersonic Missions CAP (Combat Air Patrol) • 150 miles subsonic cruise to station • Loiter • Accel, M = 0.7 to 1.35, then dash 25 nm - 4 1/2 minutes and 50 nm total • Then, must head home, or to a tanker! DLI (Deck Launch Intercept) • Energy climb to 35K ft, M = 1.5 (4 minutes) • 6 minutes at M = 1.5 (out 125-130 nm) • 2 minutes Combat (slows down fast) After 12 minutes, must head home or to a tanker. In this chapter we will explain the key supersonic aerodynamics issues facing the configuration aerodynamicist. We will start by reviewing the most significant airplanes that had substantial sustained supersonic capability. We will then examine the key physical underpinnings of supersonic gas dynamics and their implications for configuration design. Examples are presented showing applications of modern CFD and the application of MDO. We will see that developing a practical supersonic airplane is extremely demanding and requires careful integration of the various contributing technologies. Finally we discuss contemporary efforts to develop new supersonic airplanes. 10.2 Supersonic “Cruise” Airplanes The supersonic capability described above is typical of most of the so-called supersonic fighters, and obviously the supersonic performance is limited.

DANIELA KINCOVÁ AUTHOR VEDOUCÍ PRÁCE Ing. RÓBERT ©O©OVIÈKA, Ph.D. SUPERVISOR BRNO 2015 Abstrakt Tato práce se zabývá problematikou zavedení a provozu nadzvukových business jetù. V dnešní době se v civilní letecké pøepravě, po ukončení provozu Concordu, žádná nadzvuková letadla nevyskytují. V dnešní době existuje mnoho projektù a organizací, které se zabý- vají znovuzavedením nadzvukových letounù do civilního letectví a soustředí se pøevážně na business jety. Hlavní otázkou je, zda je vùbec vhodné, èi rozumné se k tomu typu dopravy znovu vracet. Existuje hodně problémù, které toto komplikují. Tyto letouny způsobují příliš velký hluk, mají obrovskou spotøebu paliva a musí øe¹it nadměrné emise, létají ve vysokých výškách ve kterých mùže docházet k problémùm s pøetlakováním kabiny, navi- gací, radioaktivním zářením apod. Navíc zákaz supersonických letù nad pevninou letové cesty omezuje a prodlužuje. Současně vznikající projekty navíc nedosahují tak velkého doletu jako klasické moderní bussjety, což zpùsobuje, že se nadzvukové business jety se na delších tratích stávají neefektivní. I pøes tyto problémy, je víceméně jisté, že k zavedení nadzvukových business jetù dojde během následujících 10 - 15 let, i kdyby to měla být jen otázka jisté prestiže velmi bohatých lidí. Summary This thesis is dealing with problematic about launching and operating supersonic business jets. Nowadays, after Concorde retirement, there are no more any supersonic aircrafts in civil transport system.
