DDA 501-K34 Gas Turbine Specifications and Dimensions3.2.4 Automation and Manning ParametersTo minimize CUVX acquisition cost, life cycle cost and personnel vulnerability during combat, it is veryimportant to reduce manning. A number of automation technologies for aircraft launch and recovery, handling,maintenance, and weapons handling were considered for CUVX including an electromagnetic aircraft launchingsystem (EMALS), advanced arresting gear (AAG) or electromagnetic aircraft recovery system (EARS), pit stopconcepts for fueling and arming aircraft, a shipboard weapons loader (SWL), and the use of fuel and weaponsaircraft modules.In concept exploration it is difficult to deal with automation manning reductions explicitly, so ship andaviation manning factors are used. These factors represent reductions from “standard” manning levels that resultfrom automation. This leads to the regression based manning equations shown in Figure 5. The manning factorsCManShip and CManAir, which vary from 0.5 to 1.0, are used as CUVX design parameters DP14 and DP19. Aship manning factor, CManShip, of 1.0 corresponds to CV-like manning. A ship manning factor of 0.5 correlatesto a 50% reduction in manning compared to a CV. These manning factors are also applied using simpleexpressions based on expert opinion for ship accommodations and support, automation cost, automation risk,damage control performance and repair capability performance. The standard manning calculations are shown inFigure 5. The values of performance for repairs and damage control are shown in Figure 6. The calculation forautomation impact on cost and risk is shown in Figure 7. A more detailed manning analysis is performed inconcept development.The simple regression-based equations are based on the following independent variables:W P : total payload weight W VP : variable payload weightW F23 : total weight of aircraft V FL : full load hull displacement volumeN SSG : number of ship service generators V D : deckhouse volumeN prop : number of propellersThe simple regression-based equations calculate the following:N EShip : number of ship enlisted men (including CPO-Chief Petty Officers)N EAir : number of air enlisted men (including CPO-Chief Petty Officers)N OShip : number of ship officersN OAir : number of air officersN E : total number of enlisted men N O : total number of officers
