Altitude Performance of a Turbojet Engine Using Pentaborane Fuel (open access)

Altitude Performance of a Turbojet Engine Using Pentaborane Fuel

Memorandum presenting a turbojet engine with a two-stage turbine operated with pentaborane fuel continuously for 11.5 minutes at a simulated altitude of 55,000 feet at a flight Mach number of 0.8. The engine incorporated an NACA combustor designed specifically for use with pentaborane fuel. Results regarding oxide formation and deposition, engine operating point, effect of oxide deposits on component performance, effect of oxide deposition on overall performance, and some operational comments are provided.

Investigation of Ejection Releases of an MB-1 Rocket From a 0.04956-Scaled Model of the Convair F-106A Airplane at Mach Number 1.59 (open access)

Investigation of Ejection Releases of an MB-1 Rocket From a 0.04956-Scaled Model of the Convair F-106A Airplane at Mach Number 1.59

Report presenting an investigation of the ejection release characteristics of the MB-1 rocket from the missile bay of a model of the Convair F-106A airplane with its fin tips retracted at a simulated altitude of 18,670 feet. Successful ejections of the rocket were made at supersonic speeds by applying a combination of ejection velocity and nose-down pitching moment at release.

Origin and Development of Leading-Edge Cracks in Turbojet Engine Buckets (open access)

Origin and Development of Leading-Edge Cracks in Turbojet Engine Buckets

Report presenting an investigation to study the origin and development of leading-edge cracking in turbine buckets made of six materials: S-816, M-252, Inconel 550, Inconel 700, Hastelloy R-235, and Jetalloy 1570. Some of the buckets were also given certain stress-relief treatments. Results regarding the development of leading-edge cracks, development of bucket fractures, comparison of performance for the material tested, macro- and microexamination of unfractured and fractured buckets,

Investigation of Ejection Releases of an MB-1 Rocket From a 0.04956-Scaled Model of the Convair F-106A Airplane at Mach Number 1.59 : Coord. No. AF-AM-57

Memorandum presenting an investigation in the 27- by 27-inch preflight jet of the ejection release characteristics of the MB-1 rocket from the missile bay of a 0.04956-scaled model of the Convair F-106A. The MB-1 rocket was ejected with its fin tips retracted, for a simulated altitude of 18,670 feet at a Mach number of 1.59.

Thermal relations for two-phase expansion with phase equilibrium and example for combustion products of boron-containing fuel (open access)

Thermal relations for two-phase expansion with phase equilibrium and example for combustion products of boron-containing fuel

Report presenting a procedure for integrating equations involving pressure, temperature, and density in order to analyze an expansion process that occurs when boric oxide from fuels condenses during expansion. An example is provided to illustrate the manner in which the equations can be used to analyze a one-dimensional expansion with phase equilibrium.

Altitude performance of a turbojet engine using pentaborane fuel (open access)

Altitude performance of a turbojet engine using pentaborane fuel

From Summary: "The primary objectives of the investigation reported herein were to determine the effect of this new combuster design on boric oxide deposition on engine parts and to determine the effect of boric oxide on the performance of multistage turbine. Pentaborance fuel (approx. 130 lb) was used in the engine performance evaluation reported herein. The data presented herein show the engine component and over-all performance deterioration with operation on pentaborane fuel".
