Special Report on Bell ACAP Full-Scale Aircraft Crash Test

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">A full-scale aircraft crash test of the Bell ACAP developed under the U.S. Army's Advanced Composite Airframe Program was conducted at NASA Langley Research Center's Impact Dynamics Facility on August 27, 1987. The test demonstrated that the Bell ACAP was capable of meeting the U.S.

SHM with FBGs on a Full-scale Composite Aircraft Part

Photonics and Fiber Technology 2016 (ACOFT, BGPP, NP), 2016
This paper discusses results obtained in a Structural Health Monitoring (SHM) test of a full-scale composite aircraft part using Fibre Bragg gratings (FBGs). The FBGs were bonded to the surface of the aircraft part to monitor the part before and after localized damage was created.

On the Dominant Noise Components of Tactical Aircraft: Laboratory to Full Scale

23rd AIAA/CEAS Aeroacoustics Conference, 2017
Abstract This paper investigates the dominant noise components of a full-scale high performance tactical aircraft. The present study uses acoustic measurements of the exhaust jet from a single General Electric F414-400 turbofan engine installed in a Boeing F/A-18E Super Hornet aircraft operating from flight idle to maximum afterburner. The full-scale

Nonlinear Normal Modes of a Full-Scale Aircraft

The objective of this paper is to demonstrate that the numerical computation of the nonlinear normal modes (NNMs) of complex real-world structures is now within reach. The application considered in this study is the airframe of the Morane-Saulnier Paris aircraft, whose ground vibration tests have exhibited some nonlinear structural behaviors.

Forebody flow control on a full-scale F/A-18 aircraft

10th Applied Aerodynamics Conference, 1992
A full-scale F/A-18 was tested in the 80- by 120-Foot Wind Tunnel at NASA Ames Research Center to measure the effectiveness of pneumatic forebody vortex control devices. By altering the forebody vortex flow, yaw control can be maintained to angles of attack greater than 50 deg.

Laser beam propagation through a full scale aircraft turboprop engine exhaust

SPIE Proceedings, 2010
The exhaust from engines introduces zones of extreme turbulence levels in local environments around aircraft. This may disturb the performance of aircraft mounted optical and laser systems. The turbulence distortion will be especially devastating for optical missile warning and laser based DIRCM systems used to protect manoeuvring aircraft against ...

Structural dynamics research in a full-scale transport aircraft crash test

Journal of Aircraft, 1987
A remotely piloted air-to-ground crash test of a full-scale transport aircraft was conducted for the first time for two purposes: (1) to demonstrate performance of an antimisting fuel additive in suppressing fire in a crash environment, and (2) to obtain structural dynamics data under crash conditions for comparison with analytical predictions.

Full-scale flight tests of aircraft morphing structures using SMA actuators

SPIE Proceedings, 2007
In August of 2005 The Boeing Company conducted a full-scale flight test utilizing Shape Memory Alloy (SMA) actuators to morph an engine's fan exhaust to correlate exhaust geometry with jet noise reduction. The test was conducted on a 777-300ER with GE-115B engines.
