Options for flight testing Rocket Based Combined Cycle (RBCC) engines. By John Robert Olds. Abstract. Issued as Report, Project EX91Report has title: Options for flight testing Rocket Based Combined Cycle (RBCC) engine Topics: Rocket engines Testing.

The two leading candidates for aerospace combined-cycle engine technology are rocket-based combined-cycle (RBCC) and turbine-based combined-cycle (TBCC).

Paper studies, computational analysis, and, in many instances, small- or full-scale ground-test data exist for a number of proposed combined-cycle engine systems.

The rocket-based combined cycle (RBCC) engine and the turbo-based combined cycle (TBCC) engine are two main choices for the combined propulsion system.

In the subsonic and the low supersonic conditions, the RBCC engine adopts an ejector rocket to carry the outside airflow into the engine while the TBCC engine adopts a turbo-compressor system.

Section 4 deals with the testing accomplished to-date and future plans for on-ground and flight vehicle testing. Section 5 addresses the maturity of various elements of the overall RBCC technology. Finally, the applicability and superior potential of the Strutjet engine, as. A rocket-based combined cycle (RBCC) engine was designed to demonstrate its broad applicability in the ejector and ramjet modes within the flight range from Mach 0 to Mach To validate the design, a prototype was fabricated and tested as a freejet engine operating at flight Mach 3.

Analysis of a new rocket-based combined-cycle engine concept at low speed. Options for flight testing rocket-based combined-cycle (RBCC) engines. John Olds; 32nd Joint Propulsion Conference and Exhibit August Rocket Based Combined Cycle engine (RBCC).

Rocket-based combined-cycle (RBCC) engines are known as the most promising type of engine with the potential to realize ‘single stage to orbit’ (SSTO). John Cramer (NASA/Marshall Space Flight Center),B,A_,_e,L4W.O • Introduction Rocketdyne Propulsion and Power (RPP) has completed a highly successful experimental test program of an advanced rocket based combined cycle (RBCC) propulsion system.

The test program was conducted as part of the Advanced Reusable Technology program directed by. Get this from a library. Options for flight testing rocket-based combined-cycle (RBCC) engines. [J Olds; United States. National Aeronautics and Space Administration.].

analyses performed for two possible options for flight testing rocket-based combined-cycle (RBCC) engines — the X and a new small TSTO vehicle development known as the W vehicle. Specific conclusions include the following. 1) Both concepts appear capable of serving as RBCC testbeds based on conceptual level preliminary analysis.

Optimization of the rocket mode trajectory in a rocket based combined cycle (RBCC) engine powered SSTO vehicle RICHARD FOSTER Astronautics Corporation of. FLIGHT TEST OPTIONS Flight Test Objectives A follow-on flight test program will serve to further enhance the database of information on RBCC engines and will almost certainly be required should the engine be selected for use on advanced launch systems.

In particular, a flight test program could be used to examine engine mode transition effects (i.e. Experimental tests are conducted to evaluate two rocket exhaust configurations within an Rocket-Based Combined Cycle engine model.

Each configuration uses a single rocket chamber but expands the rocket exhaust to a different geometry.The RBCC, or Rocket-Based Combined Cycle propulsion system, is one of the two types of propulsion systems that may be tested in the Boeing X experimental aircraft. The RBCC, or strutjet as it is sometimes called, is a combination propulsion system that consists of a ramjet, scramjet, and ducted rocket, where all three systems use a shared flow path.In this study, quasi-1D analysis with chemical equilibrium was applied at a sub-scale rocket-based combined cycle (RBCC) engine for a hypersonic flight test using a sounding rocket.

A mission profile of the engine was designed in a previous study, and its off-design performance was examined in test-mission research for the flight test.
