Zustand: sehr guter Zustand. F. sehr guter Zustand, geringe Gebrauchs- und Alterungsspuren: Deckel und erste Textseite mit altem Stempel, Deckel auch noch mit Nummer und Notiz - Seiten sauber und ordentlich A study of the loss and velocity distribution in a radial flow impeller was made. It is indicated that secondary flows within the boundary layer and leakage through the blade-to-shroud clearance space result in a concentration of low-energy air at approximately 80 percent of the passage width from the pressure face at the shroud. Comparison of the data from internal measurements made for the impeller of this investigation with hot-wire anemometer studies made at the outlet of a similar impeller indicates that much can be learned about the internal flow picture with hot-wire surveys alone.

Zustand: sehr guter Zustand. F. sehr guter Zustand, geringe Gebrauchs- und Alterungsspuren: Deckel und erste Textseite mit altem Stempel, Deckel auch noch mit Nummer - Umschlag und Seiten teils etwas eselsohrig - Deckel teils leicht verschmutzt - Seiten sauber und ordentlich An analysis method and a design method are developed for one-dimensional, compressible flow with friction, heat transfer, and area change in vaneless diffusers with arbitrary profiles in the axial-radial plane. In the analysis method the variations in fluid properties are determined as a function of radius for a prescribed variation in diffuser wall spacing with radius. In the design method the variation in effective diffuser wall spacing is determined as a function of radius for an arbitrary prescribed variation in one fluid property.

Zustand: sehr guter Zustand. F. sehr guter Zustand, geringe Gebrauchs- und Alterungsspuren: Deckel und erste Textseite mit altem Stempel, Deckel auch noch mit Nummer - Umschlag und Seiten teils etwas eselsohrig - Seiten sauber und ordentlich Presents analysis of composite engine comprising piston engine, blowdown turbine, and steady-flow turbine with particular emphasis on cost of design compromises in operation of the engine over the range of altitudes and powers. For geared-in turbines, compressor losses were sometimes large and the altitude range was restricted. By the use of an auxiliary propeller, these losses could be reduced. The weights of the engines were not considered in the evaluation.

Hardcover. Zustand: Good. 1st Edition. Huge oversized hardcover. Vellum colored paper spine, with gold lettering. Colored balloon on the front cover with large gold lettering. Binding good and tight. Some scuffing and wear to the bottom edges of the covers and some general wear and fading to large, heavy boards. The front endpaper has a double crease, which is flattening out as it sits on my shelf. Bookplate on the inside front cover, "Library of the National Air Museum. Presented. by Dr. John F. Victory. 1960." Signed twice by Victory above the bookplate - once with inscription to National Air Museum dated 1960, and again without a date at the top of the page. John Victory was the Executive Secretary of NASA (formerly NACA) and was its first paid employee, having been hired in 1915. In addition, there is a letter tucked inside from the Real Accademia d'Italia and signed by its president; 10 typed lines which I cannot read because I don't speak Italian A limited edition of 500 copies. This copy is not numbered. 174 plates (single sided, black and white) and 184 pages of text, in Italian. Very good condition. An ambitious and beautiful collection of Italian flight, from balloons to planes. A huge and heavy book with interesting provenance. Extra shipping will be required for shipping; it weighs nearly 10 lbs. Please email with questions or to request photos. Signed by Author(s).
