28 of the Advanced Launch System (ALS), Advanced Development Program (ADP) Liquid Hydrogen Turbopump. This program is being performed by Aerojet Propulsion Division for the Marshall Space Flight Center (MSFC), NASA, under Contract No.

NAS The purpose of this document is to define the interface criteria for the Turbopump Test Article and the Component Test Facility. Get this from a library. Liquid hydrogen turbopump ALS advanced development program.

Marshall Space Flight Center.;]. For the purposes of this ICD, the test article consists of the Hot Fire Drive Turbopump mounted on its test cart, readied for installation in the component test facility.

It should be emphasized that the LH2 turbopump program is still in its early concept design phase. The interface criteria for the Turbopump Test article (TPA) and the Component Test Facility located at NASA, Stennis Space Center is defined by this interface Control Document (ICD).

TPA ICD Volume 2 is submitted for the Cold Gas Drive Turbopump Test Article, which is generally similar but incorporates certain changes, particularly in Liquid hydrogen turbopump ALS advanced development program. book requirements and in instrumentation : Bruce Lindley.

These modifications include the following: (1) the dual pump discharge arrangement was changed to a single discharge; (2) commonality of the turbine inlet manifold with the advanced launch system (ALS) liquid oxygen (LOX) TPA was dropped for this program; (3) the turbine housing flange arrangement was improved by relocating it away from the first stage nozzles; (4) a ten percent margin (five percent Author: Nancy R.

Shimp and George J. Claffy. Advanced Development Programs are being pursued by Rocketdyne, Aerojet, and Pratt & Whitney to define and validate design approaches toward producing low-cost, reliable liquid-hydrogen and liquid-oxygen turbopumps for a kN ( klb) thrust Advanced Launch : A. Csomor, C.

Faulkner, F. Ferlita. An initial design of a split flow liquid hydrogen turbopump for the Dual Expander Aerospike Nozzle (DEAN) upper stage engine was completed. The engine nozzle is an annular aerospike. The engine cycle requires a combustion chamber pressure of 1, psia.

The DEAN is designed to deli lbf of thrust and seconds of by: 3.

These models have been developed within the Concurrent Design Facility, under development at the Italian Aerospace Research Centre (CIRA), Cited by: 1. liquid-hydrogen turbopumps for a kN ( klb) gas generator cycle ALS engine. Similarly, Pratt & Whitney has been awarded an advanced development contract for the LOX turbopump.

All contracts are for 45 months. At the publication of this paper, all three companies are nearing the conclusion of the month Phase I effort. During this.

Helium gas for valve actuation is controlled by solenoid valves, which are compactly mounted in a pneumatic package and act in accordance with signals from a micro computer called engine control box. Nakanishi et al, Fig. 4 Liquid Oxygen Turbopump Fig.

The turbopump internal design of the SSTP, including the inter-propellant seal, the configuration pumps and turbine, the rotordynamic characteristics, the damping supports, the dynamic and static seals, were all based on KBKhA’s 60 years of experience developing single File Size: KB.

Not surprisingly, the development of cryopumping went in parallel with the advances made in liquefaction (liquid nitrogen, K, Dewar, ; liquid hydrogen K, Dewar, ; liquid helium, K, Kammerlingh Onnes, ). It was soon found that vacuum can be produced by charcoal kept at these cryogenic temperatures.
