This book was released on 1996 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new software release designated version 154.0 has been developed and tested for use on the F/A-18 High Angle-of-Attack Research Vehicle (HARV). This software release incorporates all software changes to the Actuated Nose Strakes for Enhanced Rolling (ANSER) control laws through version 153.0 with the following exceptions. The first exception is a modification of the On-Board Excitation System (OBES) which replaces the OBES load in version 153.0 with 17 new maneuvers. The second exception is to change the symmetric strake deployment schedule back to the original schedule in ANSER control law version 151.1. The final change replaces two instrumentation parameters. These three modifications make up the new software release for use in the Research Flight Control System (RFCS) flight control computer. This report documents the batch versus Hardware-in-the-Loop Simulation test results for version 154.0.

This book was released on 1996 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Actuated Nose Strakes for Enhanced Rolling (ANSER) Control Laws were modified as a result of Phase 3 F/A-18 High Alpha Research Vehicle (HARV) flight testing. The control law modifications for the next software release were designated version 152.0. The Ada implementation was tested in the Hardware-In-the-Loop (HIL) simulation and results were compared to those obtained with the NASA Langley batch Fortran implementation of the control laws which are considered the 'truth model.' This report documents the performance validation test results between these implementations for ANSER control law version 152.0.

This book was released on 2018-07-25 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the NASA High-Alpha Technology Program the High Alpha Research Vehicle (HARV) was used to conduct flight tests of advanced control effectors, advanced control laws, and high-alpha design guidelines for future super-maneuverable fighters. The High-Alpha Research Vehicle is a pre-production F/A-18 airplane modified with a multi-axis thrust-vectoring system for augmented pitch and yaw control power and Actuated Nose Strakes for Enhanced Rolling (ANSER) to augment body-axis yaw control power. Flight testing at the Dryden Flight Research Center (DFRC) began in July 1995 and continued until May 1996. Flight data will be utilized to evaluate control law performance and aircraft dynamics, determine aircraft control and stability derivatives using parameter identification techniques, and validate design guidelines. To accomplish these purposes, essential flight data parameters were retrieved from the DFRC data system and stored on the Dynamics and Control Branch (DCB) computer complex at Langley. This report describes the multi-step task used to retrieve and process this data and documents the results of these tasks. Documentation includes software listings, flight information, maneuver information, time intervals for which data were retrieved, lists of data parameters and definitions, and example data plots.

This book was released on 2018-11-03 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains a description of a lateral-directional control law designed for the NASA High-Alpha Research Vehicle (HARV). The HARV is a F/A-18 aircraft modified to include a research flight computer, spin chute, and thrust-vectoring in the pitch and yaw axes. Two separate design tools, CRAFT and Pseudo Controls, were integrated to synthesize the lateral-directional control law. This report contains a description of the lateral-directional control law, analyses, and nonlinear simulation (batch and piloted) results. Linear analysis results include closed-loop eigenvalues, stability margins, robustness to changes in various plant parameters, and servo-elastic frequency responses. Step time responses from nonlinear batch simulation are presented and compared to design guidelines. Piloted simulation task scenarios, task guidelines, and pilot subjective ratings for the various maneuvers are discussed. Linear analysis shows that the control law meets the stability margin guidelines and is robust to stability and control parameter changes. Nonlinear batch simulation analysis shows the control law exhibits good performance and meets most of the design guidelines over the entire range of angle-of-attack. This control law (designated NASA-1A) was flight tested during the Summer of 1994 at NASA Dryden Flight Research Center.
