Gluhareff dart missile?

These sites mention a dart-shaped missile designed by Mr. Michael Gluhareff for Ludington-Griswold company which was then tested by NACA:

"In 1942 Griswold's company had built a wind tunnel model of a dart-shaped missile conceived by Michael Gluhareff, a Russian émigré who was chief of design for the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation; now, in 1944, Griswold was using the results of Vought-Sikorsky tunnel tests with the model to convince the AAF and the NACA that the new missile should be developed."

"Eventually, a wind tunnel model was built; initial tests were encouraging. But the Army declined to follow up due to several other unconventional projects already under way. Fortunately, a business associate of Gluhareff kept the concept alive by using the Dart design, as it was called, as the basis for an air-to-ground glide bomb in 1944."

Is there anything else available about this project?

There was a 10p. article in Aerospace Historian , Spring ,March 1979.

"Lippisch,Gluhareff and Jones: The Emergence of the Delta Planform and the
Origins of the Sweptwing in the United States".

What kind of missile was it?, an air to ground one for heavy bombers?

and what about its powerplant?, jet, rocket or piston engine?

Perhaps the Gluhareff patent n° 2,511,502 filed on June 5, 1946, gives some clues about that missile:

"Figs. 1 to 4 show a dart-shaped airplane embodying the invention in the form of a pilotless missile, the flight path of which may be controlled by radio or in any well-known manner usual in the art of guided missiles."
"In Figs. 5 to 8 there is shown a somewhat similar form of guided, missile except that the leading edge of the airfoil-body in the vicinity of the longitudinal axis is provided with a forwardly projecting bulged airfoil body portion (24) of airfoil cross-section which is well pointed at its forward end and which merges-aft into the main
wing airfoil (10). This body (24) may house the control apparatus or in some instances, may
carry the explosive charge of the missile."

Roger W Griswold II, the same griswold of Ludington Griswold and my great grandfather, was the one who transitioned the dart design into a glomb. The AAF then told him to get the opinion of NACA. RT Jones analyzed it using atypical calculations as the accepted model would not be adequate given the shape of dart, and while the results were promising, he thought the crude equations would garner little interest . A year later Jones revisited the equations he used to analyze the dart which led to the development of multiple swept wing jets.
