SECRETARY’S REPORT 137 
LocKHEED ArRcRAFT Corp., Burbank, Calif. (through Washington, D.C., repre- 
sentative) : Secale models, 1:48 size, of a Lockheed Q-5 drone, which is an 
unmanned radio-guided aircraft in current use by the U.S. Air Force as a 
supersonie missile target; and a Lockheed X-7 research vehicle used as a 
flying test bed for ramjet engines. (N.A.M. 978.) 
Martin Co., THE, Baltimore, Md.: Two scale models of Martin pilotless air- 
eraft in current use: The Air Force “Matador” TM-61B guided missile, 
and the Navy “Vanguard” earth satellite vehicle. (N.A.M. 977.) 
McCautry, Ernest G., Fort Lauderdale, Fla.: Two 2-bladed metal propellers 
for airplanes; production examples invented by the donor. One is of solid 
steel and adjustable pitch with an airfoil of thin section to reduce weight 
and of concave-convex shape to improve rigidity. Following a test by the 
Army Air Corps in 1933 when this make of propeller improved the takeoff, 
climb, and speed of a training plane, it was adopted by both the Army and 
Navy, for use with trainers, and continued in use for 10 years. The other 
propeller received, with the trade name MET-L-PROP, was developed in 1947 
for use with light airplanes. It is of aluminum alloy, fixed pitch, forged 
in one piece including the hub section. (N.A.M. 990.) 
NaFE, Dr. JOHN ELLIOTT, Columbia University, Palisades, N. Y.: The cap and 
gown worn by the late Robert Hutchings Goddard, “Father of Rocketry,” 
when receiving his doctorate of physics at Clark University, 1912 (loan). 
(N.A.M. 998.) 
NATIONAL ADVISORY COMMITTEE FoR AERONAUTICS, Langley Field, Va.: A Nike- 
Cajun sounding rocket, the N.A.C.A. jet-supported platform which utilizes 
a teetering rotor, the N.A.C.A. jet-supported platform which utilizes a jet 
of compressed air, and an N.A.C.A. wing flow balance. (N.A.M. 963.) 
NAVY, DEPARTMENT OF THE, Washington, D.C.: An enlarged photograph of 
a De Havilland-4B airplane, one of the U.S. Air Force Service types flown 
by Brig. Gen. William Mitchell in 1921. Enlargement made from an Air 
Force negative for exhibition with General Mitchell’s statue. (N.A.M. 
968). A full-size exterior duplicate of the “Vanguard” rocket-powered satel- 
lite vehicle which on March 17, 1958, carried America’s second satellite into 
orbit around the earth. This achievement by the U.S. Navy, with the vehicle 
manufactured by The Martin Company, followed about six weeks after the 
U.S. Army’s “Jupiter” had carried America’s first satellite, the “Explorer,” 
into orbit, and over 5 months after Russia had made the initial success. 
This “Vanguard” was formally received for the National Air Museum by Dr. 
Leonard Carmichael, Secretary of the Smithsonian Institution, from Rear Adm. 
Rawson Bennett, Chief of Naval Research. The ceremony was held in the 
rotunda of the Arts and Industries Building of the U.S. National Museum 
where the top of the “Vanguard,” exhibited in launching position, reaches 
72 feet in height. Near the floor beside the vehicle is shown a reproduction 
of the 6-inch-diameter, 314-pound satellite which has been continuously 
circling the earth since launched, and will probably continue to orbit for years 
tocome. (N.A.M. 992.) 
NEVIN, Rosert §., Denver, Colo.: A 1:16-size scale model of the Wright Com- 
pany type “H” airplane of 1915; a 2-place, twin-pusher biplane, developed 
as a weight carrier with a useful load of 1,000 pounds and speed of 56 mph. 
Model constructed by Mr. Nevin (purchase). (N.A.M. 947.) 
NEwsurRGH Free AcapeMy, Newburgh, N.Y.: A LeRhone rotary engine, air 
cooled; a type used in World War I. Its nine cylinders radiate from the 
central crankcase and revolve like the spokes of a wheel. (N.A.M. 987.)
