Problem Statement
This project will serve to provide a background study on past wars in terms of their fuel usage, and compare them to the metrics of modern day warfare. What is needed, and what will be answered here subsequently is that given various future warfare scenarios, how will helicopters be leveraged and used in those scenarios? The largest issue being fuel efficiency, the efficiency of helicopters from a tactical perspective as well as a design perspective will need to be applied to each of the future scenarios to provide feasibility guidance in the next 10 to 20 years of helicopter production by vendors, specifically Sikorsky.

Approach and Methodology
1. Survey the use of energy in warfare throughout history and develop energy consumption metrics
2. Identify a range of representative scenarios• Primary missions• Army, Navy, Marine Corps, Air Force
3. Identify technologies for inspection and characterization4. Conduct cost estimation of fuel prices in 2021 and 20315. Model Scenarios6. Analysis
• Vary fuel price• Apply technologies• Conduct excursions for potential changes in future warfare
– Provide insight and recommendation for the impact of fuel efficiencies and rotary aircraft

MetricsMetrics capture how fuel is expended and any benefits of increased fuel
efficiency
• Time to complete mission– Reduced mission time by removing the need to refuel eliminating delays
– Lighter aircraft may move faster
• Lift capacity– Carrying less fuel or building a lighter aircraft may allow additional lift capacity (up to
the structural limitations of the aircraft)
• Time on station (TOS)– Move efficient fuel/aircraft may extend legs or increase TOS
• Cost– Less fuel burned = lower cost
– Alternate fuel = lower price?
– All metrics will be translated into cost as well• $/mile• $/lb lift• $/flight hour

per Soldier per Day since Vietnam War
• Fuel Consumption of 22 Gallons/Soldier/Day in Iraq/Afghanistan War w/ a Projected Burn Rate of 1.5%/Year through 2017
![Page 28: ILF: Interim Progress Report Jess Kaizar, Hong Tran, Tariq Islam.](https://reader035.fdocuments.us/reader035/viewer/2022062715/56649da75503460f94a929c0/html5/thumbnails/28.jpg)
• Defense Energy Support Center (US Military's Primary Fuel Broker) has contracts with the International Oil Trading Company; Kuwait Petroleum Corporation and Turkish Petrol Ofisi, Golteks and Tefirom. Contracts with these companies range from $1.99 a gallon to $5.30 a gallon.
• DESC sets fuel rates paid by military units. $3.51 a gallon for diesel $3.15 for gasoline $3.04 for jet fuel Avgas -- a high-octane fuel used mostly in unmanned aerial vehicles -- is sold for $13.61 a gallon• Fuel Protection (from Ground & Air)• Accidents/Pilferage/Weather• IEDs• Inventory/Storage Due to Many Types of Fuel• Final Delivery Cost of $45 -$400/gallon to Remote Afghanistan
(lack of infrastructure, challenging geography, increased roadside attacks)

• 2001 DSB Report Recommends the Inclusion of
fuel efficiency in requirements and acquisition processes.
• Target fuel efficiency improvements through investments in Science and
Technology and systems design• The Principal Deputy Under Secretary ofDefense signed a memo stating “…include fuel
efficiency as a Key Performance Parameter (KPP) in all Operational Requirements Documents and Capstone Requirements Documents.”
