This paper gives an overview of the NASA F-18 High Alpha Research Vehicle. The three
flight phases of the program are introduced, along with the specific goals and data examples …

TAIL buffet occurs when the vortex shed from a strake or a leading-edge extension (LEX)
bursts immediately forward of the tail. Although tail buffet can be a problem for any aircraft, it …

Computational analysis of flow over the F/A-18 aircraft is presented along with
complementary data from both flight and wind tunnel experiments. The computational results …

The unsteady pressures acting on the vertical tails of a fullscale FIA-18 fighter aircraft were
studied to gain a better understanding of tail-buffet loads that frequently occur on fighter …

THE impingement of a streamwise vortex on an aerodynamic surface, such as a Ūn or tail,
can result in efŪciency loss, severe unsteady loading, vibration, and adverse stability and …

This paper presents a numerical simulation of the c~ xternal and engine inlet flows for the F-
18 aircraft at typical liigli-angle-of-attnck flight conditions. Two engine inlct Inass flow rates …

This research proposes a systematic approach with which the decision makers can evaluate
the value and risk of a new aircraft development program, including potential derivative …
