Reliability as an Independent Variable Applied to Liquid Rocket Engine Hot Fire Test Plans

Autor: Jeffrey W. Herrmann, Richard Strunz

Publikováno v: Journal of Propulsion and Power. 27:1032-1044

Manufacturers lack an adequatemethod to balance performance, reliability, and affordability. The reliability-asan-independent-variable methodology is the solution proposed by expressing quantitatively the reliability trade space as ranges of a number

A reliability as an independent variable (RAIV) methodology for optimizing test planning for liquid rocket engines

Autor: Jeffrey W. Herrmann, Richard Strunz

Publikováno v: CEAS Space Journal. 2:17-30

The hot fire test strategy for liquid rocket engines has always been a concern of space industry and agency alike because no recognized standard exists. Previous hot fire test plans focused on the verification of performance requirements but did not

A liquid rocket engine conceptual design tradeoff methodology using an a priori articulation of preference information with epistemic uncertaintie

Autor: Richard Strunz, Simon A. Krueger, Jeffrey W. Herrmann

Publikováno v: 51st AIAA/SAE/ASEE Joint Propulsion Conference.

Liquid rocket engine program management involves decision-making with multiple, usually conflicting, and correlated objectives like performance/weight, demonstrated reliability, initial operational capability, and affordability that include program r

Planning, tracking, and projecting reliability growth a Bayesian approach

Autor: Jeffrey W. Herrmann, Richard Strunz

Publikováno v: 2012 Proceedings Annual Reliability and Maintainability Symposium.

Liquid rocket engine reliability growth modeling is a blend of art and science because of data scarcity and heterogeneity, which result from the limited number of engine development programs as well as testing profiles that are much different from th

An Overview of the Development of the Catalytic Igniter for the Next Generation Launcher

Autor: W. Kwan, H. Snijders, Alfons Mayer, Thierry Kachler, Richard Strunz, Bernd Brauers

Publikováno v: 46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit.

Presently APP and TNO are working on the development of a versatile catalytic igniter, which can be utilized for various rocket engines. This igniter can replace the presently used pyrogen and spark torch ignition systems. Key advantages of the syste
