Book excerpt: This is one of a series of reports on the lessons learned from past research related to lift-fan aircraft concepts. An extensive review is presented of the many lift-fan aircraft design studies conducted by both government and industry over the past 45 years. Mission applications and design integration including discussions on manifolding hot gas generators, hot gas dusting, and energy transfer control are addressed. Past lift-fan evaluations of the Avrocar are discussed. Lessons learned from these past efforts are identified. Deckert, Wallace H. Ames Research Center...

This book was released on 2018-07-16 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary is presented of some of the lift and lift/cruise fan technology including fan performance, fan stall, ground effects, ingestion and thrust loss, design tradeoffs and integration, control effectiveness and several other areas related to vertical short takeoff and landing (V/STOL) aircraft conceptual design. The various subjects addressed, while not necessarily pertinent to specific short takeoff/vertical landing (STOVL) supersonic designs being considered, are of interest to the general field of lift and lift/cruise fan aircraft designs and may be of importance in the future. The various wind tunnel and static tests reviewed are: (1) the Doak VZ-4 ducted fan, (2) the 0.57 scale model of the Bell X-22 ducted fan aircraft, (3) the Avrocar, (4) the General Electric lift/cruise fan, (5) the vertical short takeoff and landing (V/STOL) lift engine configurations related to ingestion and consequent thrust loss, (6) the XV-5 and other fan-in-wing stall consideration, (7) hybrid configurations such as lift fan and lift/cruise fan or engines, and (8) the various conceptual design studies by air-frame contractors. Other design integration problems related to small and large V/STOL transport aircraft are summarized including lessons learned during more recent conceptual design studies related to a small executive V/STOL transport aircraft.

Available in PDF, EPUB and Kindle. Book excerpt: The availability of land bases from which to launch and maintain military, diplomatic, and humanitarian relief operations is becoming increasingly uncertain because of physical or political constraints. The ability to operate from a sea base, therefore, is likely to become more and more important. The Defense Science Board recently concluded that Sea Basing will be a critical future joint military capability and that DOD should proceed to develop such capability. Following the DSB report, the Navy requested that the National Research Council (NRC) convene a workshop to assess the science and technology base, both inside and outside the Navy, for developing Sea Basing and to identify R&D for supporting future concepts. This report of the workshop includes an examination of Sea Basing operational concepts; ship and aircraft technology available to make Sea Basing work; and issues involved in creating the sea base as a joint system of systems.

Download or read book Survey of Lift-Fan Aerodynamic Technology written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-16 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Representatives of NASA Ames Research Center asked that a summary of technology appropriate for lift-fan powered short takeoff/vertical landing (STOVL) aircraft be prepared so that new programs could more easily benefit from past research efforts. This paper represents one of six prepared for that purpose. The authors have conducted or supervised the conduct of research on lift-fan powered STOVL designs and some of their important components for decades. This paper will first address aerodynamic modeling requirements for experimental programs to assure realistic, trustworthy results. It will next summarize the results or efforts to develop satisfactory specialized STOVL components such as inlets and flow deflectors. It will also discuss problems with operation near the ground, aerodynamics while under lift-fan power, and aerodynamic prediction techniques. Finally, results of studies to reduce lift-fan noise will be presented. The paper will emphasize results from large scale experiments, where available, for reasons that will be brought out in the discussion. Some work with lift-engine powered STOVL aircraft is also applicable to lift-fan technology and will be presented herein. Small-scale data will be used where necessary to fill gaps.

Download or read book Lift Fan Propulsion Concepts Study written by Donald P. Gleiter and published by . This book was released on 1976 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contractor's conceptual designs of multimission lift fan VSTOL aircraft based on two different fan designs, one with a tip-turbine drive and one with a mechanical drive, were compared to determine the more suitable propulsion system for a Navy ASW aircraft with an initial operational capability in 1985. The comparison was based on consideration of propulsion system performance, propulsion-induced effects, propulsion system effects on flying qualities and control system design, aircraft mission performance, propulsion system cost, aircraft reliability and maintainability, and propulsion system vulnerability. The mechanically-driven fans were found to be more suitable, primarily because of differences in mission performance and cost. However, it was determined that aircraft could be designed to meet Navy mission requirements using either fan design. An aircraft design based on the mechanically-driven fan concept was optimized to an ASW mission for comparison with the contractor's multimission aircraft. It was found that the contractor's takeoff gross weight estimates accurately represented an aircraft optimized for the ASW mission. (Author).
