L3 Presentation at Williams Foundation Seminar on New Approaches to Air-Land ...ICSA, LLC
In this presentation by Mr Victor King, L-3 Mission Integration, to the Williams Foundation, the focus was upon how to leverage commercial technologies to augment C2 and ISR capabilities for the ADF.
The seminar focused on the way ahead with regard to air-land integration.
Air Force needs to be capable of delivering air and space power effects to support conventional and special operations in the land domain. Air Force’s Plan Jericho and Army’s Plan Beersheba need to align if there is to be a coordinated approach to integrating air base operations, air mobility, close air support, intelligence, surveillance and reconnaissance (ISR) and rotary wing aviation. To date, little attention has been paid to the integration of technology across service lines, the development of integrated tactics, techniques and procedures (TTPs) and a coherent joint collective training program. Air Force and Army need to remediate existing deficiencies and implement a capability management process that leaves it postured to take advantage of the transformative nature of fifth generation technology. The seminar explored the art of the possible in future Air-Land operations.

A gas turbine uses a gaseous working fluid to generate mechanical power that can power industrial devices. It has three main parts - an air compressor, combustion chamber, and turbine. The air is compressed in the compressor, mixed with fuel and ignited in the combustion chamber, and the hot gases spin the turbine to generate power. Some applications of gas turbines include aviation, power generation, and the oil and gas industry. The efficiency of gas turbines is typically 20-30% compared to 38-48% for steam power plants.

Pump efficiency curve - 8th October 2009CangTo Cheah
This document discusses methods for predicting pump hydraulic efficiency curves. It presents calculated efficiency curves for different specific speeds and describes alternative methods for linking efficiency to factors like rotating speed and volume flow rate. Graphs show efficiency curves and how a shift factor is used to modify the base efficiency curve based on specific speed. The curves and methods presented resemble those in Karassik's textbook on pump efficiency.
Thermodynamics of axial compressor and turbine - 3rd December 2009CangTo Cheah
This document discusses the thermodynamics of axial compressors and turbines used in gas turbines. It provides an overview of the Brayton cycle and discusses how to calculate the shaft power required for compression, temperature rises in the compressor, and outlet temperature as a function of pressure ratio, inlet temperature, and isentropic efficiency. Higher compression ratios are desirable because they increase turbine efficiency and overall gas turbine efficiency, though the rate of efficiency improvement decreases at higher ratios. Designing high-efficiency machines requires balancing increased efficiency from high compression against diminishing returns.
Gas turbine efficiency - 7th January 2010CangTo Cheah
This document discusses the ideal efficiencies of various gas turbine cycles including simple, heat exchange, reheat, and reheat with heat exchange cycles. It provides graphs comparing the efficiencies of these cycles at different pressure ratios. A simple cycle has the highest efficiency at higher pressure ratios, while a heat exchange cycle is best for lower pressure ratios. Adding reheat or combining with heat exchange does not increase efficiency compared to a simple cycle beyond certain pressure ratio thresholds. The optimal configuration depends on the operating pressure ratio of the turbine.

Axial compressor theory - stage-wise isentropic efficiency - 18th March 2010CangTo Cheah
This document discusses the theory of stage-wise isentropic efficiency in axial compressors. It covers determining the pitch and chord between blades, calculating the number of blades based on pitch, and formulas for static pressure rise and forces acting on cascades, including lift and drag forces. Graphs are presented for mean deflection and stagnation pressure loss as functions of incidence angle. The document aims to calculate coefficients for drag, lift, and loss based on these graphs and the presented formulas.
Axial compressor theory - stage-by-stage approach - 28th January 2010CangTo Cheah
The document discusses the stage-by-stage sizing approach for axial compressors. This approach allows designers to calculate blade angles and estimate pressure rise, temperature rise, and frictional losses at each stage. It introduces concepts like the de Haller number to minimize losses. A case study on the RB211-24G engine axial compressors is presented, showing blade angles and performance across 7 low pressure and 6 high pressure stages.
Axial compressor - variation of rotor and stator angles from root to tip - 4t...CangTo Cheah
The document discusses the theory behind how rotor and stator angles in an axial compressor vary from the root to the tip. It presents equations showing how angles, velocities, and other parameters change based on radial position. The analysis aims to evaluate these variations while maintaining constant specific work input at all radii, which provides a constant stage pressure ratio up to the blade height. The equations derived indicate that for certain rotor and stator velocity distributions, the two design conditions of constant specific work input and arbitrary whirl velocity profiles are compatible.
This document shows a Campbell diagram plotting the natural frequencies of five modes of a machine on the y-axis against operating speed on the x-axis. The diagram identifies the critical speeds where resonance may occur due to the operating speed matching natural frequencies, such as at 25,000 rpm where Mode 5's natural frequency aligns with 5 times the operating speed's excitation frequency.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Rolls-Royce claimed additional fuel gas heaters were needed for gas turbine packages due to changes in gas compositions after the purchase order. The study analyzed the phase behavior of the original and new gas mixtures to determine if the minimum 50K dew point margin could be met by the existing heater. For cases 2, 3, 4, and 6 the margin was less than 50K with just the existing heater but greater than 50K when including an additional heater, justifying Rolls-Royce's request. The high dew point margin of 50K compared to other suppliers' 28K standard may have been due to uncertainties around the gas properties and limited vapor saturation curve data provided to Rolls-Royce
This document summarizes the analysis of stream conditions at various points in a liquefied natural gas plant using the Peng-Robinson-Nishiumi-Arai-Takeuchi equation of state to model phase behavior. Key streams were checked to determine if they were in the vapor or vapor-liquid region. For streams in the vapor-liquid region, the mole fractions of components in the vapor and liquid phases were calculated. The results from the equation of state were compared to values provided in the plant design documents. The summary concludes that the equation of state performed well but that more complex equations may provide improved accuracy.
This document contains the results of a compressor sizing analysis using Lüdtke's method. It sizes a six-stage axial compressor to a duty of 66.3600 mmscfd at a discharge pressure of 130.4220 bara. Key details include:
- The compressor has six wheels ranging from 4270 to 5217 rpm, with polytropic efficiencies from 83.55-85.63%.
- Total polytropic head is 107493 J/kg, with individual wheel heads from 14903-20743 J/kg.
- Inlet volume flow is 15927 m3/hr with a mass flow of 874194 kg/hr.
- Discharge
This document compares screw compressor and centrifugal compressor options for a chlorine gas compressor. Centrifugal compressors generally have higher efficiencies but lower turndown capability compared to screw compressors. For this application, a centrifugal compressor could provide annual electricity savings of $147,000 due to its lower power requirement. However, screw compressors are better suited if large swings in gas composition are expected, as centrifugal performance is more sensitive to changes in gas properties. Maintenance is easier for options with vertically-split casings. The document provides detailed technical considerations and specifications from multiple compressor vendors for each compressor type.
Attachment 5_Wheatstone Type 2_6th Aug 2012CangTo Cheah
The document summarizes a performance test of a Wheatstone PTC10 Type 2 compressor on the Apache (D14) bundle. Key points:
- The test was conducted at Dresser-Rand's test facility to evaluate performance at the guaranteed point of 0.0148 flow coefficient, 0.6604 work input factor, and 0.8130 polytropic efficiency.
- Testing was done at 3530 rpm using CO2 as the test gas. Additional points were taken at 110% speed, 95% speed, and the Apache maximum power point.
- Test results showed good alignment with predicted polytropic efficiency but lower polytropic head coefficient. Discharge pressure could be achieved by increasing
Attachment 4_How to trim LP stage flow limits for 2-stage compressionsCangTo Cheah
1) The document contains performance curve data for a multi-stage compressor, including plots of polytropic head and efficiency versus volume flow for each stage.
2) To evaluate the operable range between stages, the author calculates discharge flow rates from stage one across its operating envelope and accounts for interstage cooling.
3) These flows are then compared to the surge and choke limits of stage two on a flow versus flow plot to identify the maximum transferable range.
4) Only approximately 1/3 of stage one's area is found to be operable due to aerodynamic mismatch between the stages.
1) The document evaluates compressor discharge temperatures if chilled water supply fails at the inter-stage cooler of a chlorine gas compressor.
2) Various cases are analyzed with different inlet temperatures and volume flows. Case C with a 50 degree C inter-stage temperature and increased inlet volume flow of 4550 m^3/hr maintains discharge temperatures below 120 degrees C.
3) It is proposed to reduce the inter-stage cooler discharge temperature from 55 to 50 degrees C to control compressor discharge temperature during a chilled water supply failure.
