Payload Fairing With Jettisonable Mass Acoustic Suppression
US Patent:
6394394, May 28, 2002
Filed:
May 9, 2000
Appl. No.:
09/567816
Inventors:
Richard L. Raun - Lindon UT
Patrick R. Oyler - Sandy UT
Bruce D. Hopkins - Salt Lake City UT
Patrick R. Oyler - Sandy UT
Bruce D. Hopkins - Salt Lake City UT
Assignee:
Alliant Techsystems Inc. - Edina MN
International Classification:
B64G 110
US Classification:
244158R, 244 1 N, 244121
Abstract:
A fairing for protecting a payload from excessive acoustic energy is disclosed. The fairing can be used with a launch vehicle for launching payloads such as satellites or the like. The invention provides structure to surround a payload and absorbs acoustic energy so that the noise is suppressed to acceptable levels and the payload is not damaged. The fairing comprises a two dimensional honeycomb core having composite face sheets and load skins bonded to each side of the core. A water barrier is connected to the inner side of the fairing to prevent moisture from entering the payload area. The fairing wall further includes a liquid which is added to the two dimensional honeycomb layer. The liquid is jettisoned during the launch of the vehicle at a predetermined time when the additional acoustic suppression provided by the mass of liquid is no longer needed. The fairing may also include an energy absorbing blanket connected to the inner side of the fairing to further suppress the energy generated by a launch vehicle.
Energetic Compositions Including Nitrate Esters, Methods Of Forming Such Energetic Compositions, And Articles Including Such Energetic Compositions
US Patent:
2013005, Mar 7, 2013
Filed:
Sep 2, 2011
Appl. No.:
13/225159
Inventors:
Richard L. Raun - Lindon UT, US

Assignee:
ALLIANT TECHSYSTEMS INC. - Minneapolis MN
International Classification:
F02K 9/08, C06D 5/00, C06B 25/00, C06B 21/00, C06B 45/06
US Classification:
102374, 1491096, 149 18, 149 88, 102530
Abstract:
Methods of forming energetic compositions include forming a premix comprising a nitrate ester, a polymer, and a stabilizer, and combining solids with the premix. Additional stabilizer may be added with the solids and may remain in a crystalline state. Some methods include dissolving a stabilizer in at least one of a plurality of nitrate esters. Energetic compositions include a continuous matrix and a stabilizer. The continuous matrix includes a nitrate ester and surrounds a solid energetic material. Some compositions include a first nitrate ester, a second nitrate ester having a decomposition rate lower than the first nitrate ester, and a stabilizer. An article includes a housing and an energetic composition in the housing.
