Book Description
The SR-71 test bed aircraft is shown to be a unique platform to flight-test large experiments to supersonic Mach numbers. The test bed hardware mounted on the SR-71 upper fuselage is described. This test bed hardware is composed of a fairing structure called the "canoe" and a large "reflection plane" flat plate for mounting experiments. Total experiment weights, including the canoe and reflection plane, as heavy as 14,500 lb can be mounted on the aircraft and flight-tested to speeds as fast as Mach 3.2 and altitudes as high as 80,000 ft. A brief description of the SR-71 aircraft is given, including details of the structural modifications to the fuselage, modifications to the J58 engines to provide increased thrust, and the addition of a research instrumentation system. Information is presented based on flight data that describes the SR-71 test bed aerodynamics, stability and control, structural and thermal loads, the canoe internal environment, and reflection plane flow quality. Guidelines for designing SR-71 test bed experiments are also provided.

Book Description
A maximum-likelihood output-error parameter estimation technique is used to obtain stability and control derivatives for the NASA Dryden Flight Research Center SR-71A airplane and for configurations that include experiments externally mounted to the top of the fuselage. This research is being done as part of the envelope clearance for the new experiment configurations. Flight data are obtained at speeds ranging from Mach 0.4 to Mach 3.0, with an extensive amount of test points at approximately Mach 1.0. Pilot-input pitch and yaw-roll doublets are used to obtain the data. This report defines the parameter estimation technique used, presents stability and control derivative results, and compares the derivatives for the three configurations tested. The experimental configurations studied generally show acceptable stability, control, trim, and handling qualities throughout the Mach regimes tested.

Book Description
The Lockheed 'Blackbird' aircraft family is arguably the most famous in the world. Developed for the USAF as reconnaissance aircraft nearly 40 years ago, SR-71s remained the world's fastest and highest-flying production aircraft throughout their operational existence. For the first time, the stories of the development program, the General Dynamics "Kingfish" competition, the M-21 and D-21 effort, the F-12 saga, and the operational history of the A-12 and SR-71 under the auspices of the CIA and the Air Force are all covered in detail.

Book Description
A flat plate and faired pod have been mounted on a NASA SR-71A aircraft for use as a supersonic flight experiment test bed. A test article can be placed on the flat plate; the pod can contain supporting systems. A series of test flights has been conducted to validate this test bed configuration. Flight speeds to a maximum of Mach 3.0 have been attained. Steady-state sideslip maneuvers to a maximum of 2 deg have been conducted, and the flow field in the test region has been surveyed. Two total-pressure rakes, each with two flow-angle probes, have been placed in the expected vicinity of an experiment. Static-pressure measurements have been made on the flat plate. At subsonic and low supersonic speeds with no sideslip, the flow in the surveyed region is quite uniform. During sideslip maneuvers, localized flow distortions impinge on the test region. Aircraft sideslip does not produce a uniform sidewash over the test region. At speeds faster than Mach 1.5, variable-pressure distortions were observed in the test region. Boundary-layer thickness on the flat plate at the rake was less than 2.1 in. For future experiments, a more focused and detailed flow-field survey than this one would be desirable.

Book Description
Written by an expert on the SR-71 Blackbird, this book offers readers a short, fascinating history of this incredible military aircraft . Lockheed's SR-71 Blackbird is one of the most iconic and famous jets ever built. Assembled in secret at Lockheed's Skunkworks, the Blackbird's vital statistics remain phenomenal decades later. It holds the airspeed record for a manned jet aircraft, operated at an altitude other aircraft could barely touch and was a marvel of technical engineering. Drawing on declassified material, leading SR-71 expert Paul Crickmore reveals the history of the most fascinating of aircraft, accompanied by a range of fantastic illustrations, photographs and facts about the world's most secret spy plane.

Book Description
For anyone who has ever wondered what it's like to fly the SR-71 on a secret Mach 3 reconnaissance mission, this book has the answer. Completely redesigned and updated with photos from author Colonel Richard H. Graham's personal archive, as well as a new introduction, Flying the SR-71 Blackbird details what an SR-71 mission entailed, from planning to donning a pressure suit to returning to base. The Lockheed SR-71, unofficially known as the Blackbird, was an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed by Lockheed Skunk Works. The aircraft flew so fast and high that not one was ever shot down, even by a missile. SR-71 pilot and instructor Colonel Richard Graham offers a rare cockpit perspective on how regular Air Force pilots and navigators transformed themselves into SR-71 Blackbird crews, turning their unique aviation talents to account in an unprecedented way. Arguably the world's foremost expert on piloting the Blackbird, Graham takes readers along on an operational mission that only a few Air Force pilots have ever experienced.
