IV. Proposal Requirements The technical proposal is the most important factor in the award of a contract. It should be specific and complete. While it is realized that all of the technical factors cannot be included in advance, the following should be included and keyed accordingly: 1. Demonstrate a thorough understanding of the Request for Proposal (RFP) requirements. 2. Describe the proposed technical approaches to comply with each of the requirements specified in the RFP, including
phasing of tasks. Legibility, clarity, and completeness of the technical approach are primary factors in evaluation of the proposals. 3. Particular emphasis should be directed at identification of critical, technical problem areas. Descriptions, sketches, drawings, systems analysis, method of attack, and discussions of new techniques should be presented in sufficient detail to permit engineering evaluation of the proposal. Exceptions to proposed technical requirements should be identified and explained. 4. Include tradeoff studies performed to arrive at the final design. 5. Provide a description of automated design tools used to develop the design.
V. Basis for Judging 1. Technical Content (35 points) This concerns the correctness of theory, validity of reasoning used, apparent understanding and grasp of the subject, etc. are all major factors considered and a reasonably accurate evaluation of these factors presented? 2. Organization and Presentation (20 points) The description of the design as an instrument of communication is a strong factor on judging. Organization of written design, clarity, and inclusion of pertinent information are major factors. 3. Originality (20 points) The design proposal should avoid standard textbook information, and should show the independence of thinking or a fresh approach to the project. Does the method and treatment of the problem show Page 2 of 6
imagination? Does the method show an adaptation or creation of automated design tools? 4. Practical Application and Feasibility (25 points) The proposal should present conclusions or recommendations that are feasible and practical, and not merely lead the evaluators into further difficult or insolvable problems.
VI. Request for Proposal
justification given for the selected design. While the economics of any design is critical to its success, the emphasis of this competition is on the technical aspects of the launch system architecture. The design team should demonstrate advantages of their airlaunched system over ground/sea based systems with comparable payload capability in terms of launch vehicle size, launch flexibility, launch site requirements, cost, operability, etc. The design team should also identify and address any risks and challenges that are unique to the proposed system.
Design of Air-Launched Orbital Vehicle 1. Opportunity Description Air-launched orbital vehicles continue to hold promise of reduced launch cost and improved access to space. Pegasus, built by Orbital Sciences Corporation, is currently the only orbital air-launched system in operation. Other air-launched orbital systems, such as Stratolaunch and DARPA sponsored ALASA program, are in development. Similar systems were also the subject of Horizontal Launch Study published by DARPA and NASA in 2011. 2. Project Objective This design competition asks teams to develop an Air-Launched Vehicle capable of delivering 5,000 lbs payloads to Low Earth Orbit. To meet the requirements of this design competition the orbital vehicle must be launched from an existing military or commercial aircraft or a credible modification thereof. Any significant modifications of the carrier aircraft, including orbital vehicle interface, must be specified and justified. Launch altitude, velocity, and attitude, as well as the number of stages and propulsion system for each stage of the launch vehicle, are to be selected in an initial trade study with
The project will require a multi-disciplinary team of students. Traditional aerospace engineering disciplines such as structures, propulsion, flight mechanics, orbital mechanics, and optimization will be involved. Teams will make significant design decisions regarding the configuration and characteristics of their preferred system. 3. Design Requirements And Constraints The undergraduate team (class) shall design an Air-Launched Orbital Vehicle to meet the following objectives: 1) The launch system shall provide costeffective and reliable delivery of 5,000 lbs payloads from the surface of the Earth to Low Earth Orbit (185 km AMSL circular orbit with 28.7° inclination). 2) The payload compartment size should be competitive with launch vehicles of similar payload capability. 3) The launch system shall be designed with a fleet operations lifetime of 20 years. 4) The launch system must meet all FAA regulatory requirements. The design solution shall focus on the orbital vehicle and interface with the carrier Page 3 of 6
aircraft, as well as propulsion systems, propellant tanks and feed lines, control systems, primary structure, thermal control systems, power systems, and vehicle health monitoring systems. 4. Data Requirements The final proposal report shall provide an overall engineering description of the design concept and detailed design information for major components and subsystems. At a minimum, the final proposal report shall contain the following: 1. Key trade studies and a justification for selection of the overall concept and each of the major subsystems. 2. Discussion of your design and concept of operation. Systems that are unique to the proposed design should be addressed in considerable detail. Generic subsystems do not require as much attention. 3. Detailed description of the proposed flight sequence and major ground operations events, such as ground transportation, propellant loading, takeoff, flight to launch altitude, orbital launch, orbital vehicle flight profile, and payload deployment. 4. Details of propulsion, vehicle sizing, trajectory, loads, structural, and payload capability analysis. 5. Critical technologies and their current Technology Readiness Level (TRL). Discussion of any required technological breakthroughs or plans for developing technologies to the required maturity. 6. Discussion of advantages of the airlaunched system over ground/sea based systems with comparable payload capability.
7. Discussion of risk mitigation strategies for key technical and programmatic risks, including the possibility of launch abort. 8. Drawings of the overall vehicle and key components or subsystems. 9. Estimate of life cycle cost for the launch system development and operation, including: ground systems development and operations costs; mission operations costs; and flight vehicle design, development, test, production, and operations costs. Operations cost should distinguish between fixed and variable costs. 5.
