The paper describes a few simulation techniques implemented to support flight testing activities and safe envelope expansion of a high performance fighter aircraft.

During flight testing, the X aircraft established several milestones. On November 6,the X achieved controlled flight at a 70° angle of attack. On Apthe second X successfully executed a rapid minimum-radius, ° turn using a post-stall maneuver, flying well outside the range of angle of attack normal for.

During the first century of flight, NASA and its predecessor, the National Advisory Committee on Aeronautics (NACA), provided the United States with significant research advances in aeronautics that have shaped aviation in all of its domains.

A Halifax bomber flight testing an initial version of H2S with Watlington on board flies into a barrage balloon cable and crashes. This incident can be related to the tragic death on 7 June of Alan Blumlein, 'radio expert from industry par excellence', when a Halifax testing an H2S prototype crashed near the Forest of Dean.

Introduction. The conceptual design of an aircraft and its aerodynamic analysis may require a fair amount of independent parameters.

Quantities as essential as the wing aspect-ratio have different optima, depending on whether the figure of merit is the acquisition cost, the direct operating costs, the take-off gross weight, or the block fuel. Cited by: Dozy and syseng68k, I am not trying to be alarmist - but I do find it very telling of the entire world of developing software, that tools like APL, FORTH, and Smalltalk, which are purpose-built for solving specific problems, are universally scorned in favor of bloated "software development universes" that operate according to internal laws that make string theory look sane.

The X flight program focused on agile flight within the post-stall regime, producing technical data to give aircraft designers a better understanding of aerodynamics, effectiveness of flight controls and thrust vectoring, and airflow phenomena at high angles of attack.

Stall is a condition of an airplane or an airfoil in which lift decreases.The primary objective of free-flight testing is to assess the inherent flight motions of a configuration and its response to control inputs.

dynamically scaled models exhibit rapid angular motions, the use of rapid full-on, full-off “flicker” type controls may be required.
