Attempts were made to prepare dinitropropyl vinyl ether (DNPVE) prepolymers of a molecular weight range of 2,000 to 4,000 with hydroxy functionality for use in cast-curable energetic binder systems. Two approaches were pursued. First, part of the dinitropropyl side chains in Poly-DNPVE were reduced to monoitropropyl groups and then hydroxymethylated with aqueous formaldehyde. The desired hydroxy-functional polymer was formed in excellent yield. In a second approach, DNPVE monomer was...

The major goal of this project was to address the properties and interactions of fine powders of interest in ceramics. In order to arrive at quantitative conclusions and assure reproducibility of data, the first requirement was to have well defined dispersions consisting of uniform particles of different chemical compositions (simple or mixed) and in different shapes. Thus, one part of the program has dealt with the synthesis of such 'monodispersed' powders. Specifically, we have produced...

Stress-wave profiles in vitreous GeO2 induced by planar and spherical projectile impact were measured using piezoresistance gauges in the 4 to 18 GPa shock pressure range. Comparison of the shock data for fused SiO2 with those for vitreous GeO2 demonstrates that range of transformation to a denser, presumably 6-fold coordinated structure in both media are similar. The Hugoniots of GeO2 and SiO2, both initially vitreous, are found to be virtually coincident if pressure in SiO2 is calculated by...

One of the most convenient and effective methods of stressing a part or structure for shearographic evaluation is thermal excitation. This technique involves heating the part, often convectively with a heat gun, and then monitoring with a shearography device the deformation during cooling. For a composite specimen, unbonds, delaminations, inclusions, or matrix cracking will deform during cooling differently than other more structurally sound regions and thus will appear as anomalies in the...

A numerical study of the aeroelastic stability of typical launch vehicle configurations in transonic flight is performed. Recent computational fluid dynamics techniques are used to simulate the transonic aerodynamic flow fields, as opposed to relying on experimental data for the unsteady aerodynamic pressures. The flow solver is coupled to an appropriate structural representation of the vehicle. The aerodynamic formulation is based on the thin layer approximation to the Reynolds-Averaged...

Results for the four year effort concerning the high temperature mechanical properties of polyphase ceramics based on Si3N4 are described. Initial work showed that subcritical crack growth at high temperature was caused by cavitation. Phase equilibria work identified the lowest melting eutectic in the Si3N4-Mg2SiO4-MgO portion of the Si-Mg-O-N system and linked the volume fraction of the residual glassy phase to material composition. Subsequent creep studies related creep mechanism to...

The effects of hot isostatic pressing on the physical and electrical properties of sintered lead zirconate titanate are presented. Hot isostatic pressing for short times (1 hour) with low applied pressures (6.9 - 20.7 MPa) at 1300 deg C is shown to produce lead zirconate titanate with a higher density than that obtained by conventional sintering techniques. Densification is shown to occur without an appreciable change in grain size. Localized microstructural inhomogenieties observed after...

A procedure was developed for slip casting Si3N4(-)Y2O3(-)SiO2 compositions. Thesilicon nitride was oxidized to supply the silica. The procedure resulted in 65 w/o slips with viscosities of 35 mPa(dot)s which, when cast, yielded compacts which were 56% of theoretical density. Slips with 70 w/o solids loading were also prepared having viscosities of 120 mPa(dot)s. The properties of the slips were influenced by the starting silicon nitride powder, dispersant, and milling media. The resulting...

Mercury is known as an endmember planet as it is the most reduced terrestrial planet with the highest core/mantle ratio. MESSENGER spacecraft has shown that its surface is FeO-poor (2-4 wt%) and Srich (up to 6-7 wt%), which confirms the reducing nature of its silicate mantle. Moreover, high resolution images revealed large volcanic plains and abundant pyroclastic deposits, suggesting important melting stages of the Mercurian mantle. This interpretation was confirmed by the high crustal...
