Overview of Low Observable Technology and Its Effects on Combat Aircraft Survivability

Abstract

The introduction of low observable (LO) technology on combat aircraft has produced a leap in aircraft survivability, but it has also raised some difficult questions. How do you quantify survivability, and because new technology tends to be expensive, how LO does an aircraft need to be to accomplish its mission? This paper will show how low observability dramatically improves combat aircraft survivability by reducing an air defense's ability to detect, track, intercept, and destroy an LO aircraft. Important aircraft signatures that can be detected such as radar, visual, infrared, and intentional emissions are discussed in detail as well as methods to reduce those signatures. LO and mission planning tactics' impacts on threat system capabilities are examined and examples of LO aircraft penetration of a notional hostile air defense are shown. The conclusion is that through the use of mission planning tactics and low signature, LO aircraft can survivably penetrate heavily defended air space with little support to accomplish their mission. Nomenclature C 3 = command, control, and communication P d = probability of detection P k = probability of kill P s = probability of survival

Flight Testing Radar Detection of the Saab 105 in Level Flight

“…Hacker and Oprisiu 4 provided a review of the roll coupling problem, Schy and Hannah 5 interpreted the instability as a jump phenomenon, Carroll and Mehra 6 introducedthe use of bifurcationanalysis for prediction of roll-coupled instability, Jahnke and Culick 7 applied bifurcation theory to compute points of onset of instability for the F-14, and Ananthkrishnanand Sudhakar 8 suggestedstrategiesto prevent jump in roll-coupled maneuvers. More recently, Goman et al 9 have reviewed the use of bifurcationmethods for nonlinear ight dynamics…”

“…Helicopters have become increasingly detectable with the ever more sophisticated infrared-guided surface-to-air missiles (SAM) [1,2]. The importantly intemal IR-sources of helicopter include plume emission and surface emissions from the following, (a) turboshaft engine hot parts or tailpipe, (b) exhaust plume, (c) airframe skin heated by the engine and plume, and (d) reflected skyshine, earthshine and sunshine from helicopter fuselage.…”

“…Stealth technology addresses aircraft signatures thus providing with the capability of deceiving enemy's air defense system [17]. It acts in a covert way, to avoid aircraft depletion rates and attempts to complete the mission objectives effectively [7].…”
