While other Mars flight vehicle concepts have proposed gliding flight with crash landings or low efficiency hovering flight with very little ground coverage, the proposed concept will combine hovering and fast forward flight capability into a single efficient aircraft that can be recharged and reused many times. The extremely low surface pressure on Mars requires new low-Reynolds number, low-density aerodynamics combined with a light-weight structure with extremely low disc loading and low wing loading. The main objectives in FY2017 are: 1) Perform a high altitude balloon drop model test from approximately 100,000 feet to gather key aerodynamic and controls data such as lift coefficient, drag coefficient, and stability characteristics in a relevant environment. An NASA Flight Opportunity Program award has been granted to the project to perform the high altitude balloon drop in the Spring of 2017.2) Begin the investigation of new fabrication techniques that will enable very low weight airframe and propeller designs. These designs may include laser cut carbon fiber frames and durable surface coverings that can withstand low temperatures and dust abrasion over long periods of time. Full-size airframes will be constructed and flown in a 60 foot diameter low pressure chamber at NASA Langley Research Center. 3) Continue flight research on vision-based autonomous navigation (visual odometry / IMU fusion) with a focus on hovering navigation in a 3-D environment simulating extreme terrain such as lava tubes and canyons. The exploration of Mars surface has focused on orbiters that can gather global scale data, and slow-moving rovers that get only local data. Recent advancements in autonomous electronic aircraft controls, structures, batteries and electric propulsion have brought these technologies to a level which will allow reusable electric flight in Mars' ultra-low density atmosphere. This type of asset that can gather data on a regional scale and from extreme terrain locations such as lava tubes and deep canyons. Characteristics of the aircraft must include extremely lightweight and robust structures for low wing loading and propeller disk loading, the ability to hover and perform precision landings in safe zones, battery recharging for repeated flights, and autonomous navigation without a global positioning system. The proposed effort for the FY2017 phase of the project will focus on advancing these key technologies and bring them together in a series of prototype demonstrations in relevant environments such as high altitude drops and low-pressure chamber testing.","destinations":[{"lkuCodeId":1518,"code":"MARS","description":"Mars","lkuCodeTypeId":526,"lkuCodeType":{"codeType":"DESTINATION_TYPE","description":"Destination Type"}}],"startYear":2017,"startMonth":10,"endYear":2018,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":110063,"canUserEdit":false,"firstName":"David","lastName":"North","fullName":"David D North","fullNameInverted":"North, David D","middleInitial":"D","primaryEmail":"david.d.north@nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":335305,"canUserEdit":false,"firstName":"Michael","lastName":"Lapointe","fullName":"Michael R Lapointe","fullNameInverted":"Lapointe, Michael R","middleInitial":"R","primaryEmail":"michael.r.lapointe@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":392233,"canUserEdit":false,"firstName":"Richard","lastName":"Howard","fullName":"Richard W Howard","fullNameInverted":"Howard, Richard W","middleInitial":"W","primaryEmail":"richard.w.howard@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":506560,"canUserEdit":false,"firstName":"Julie","lastName":"Williams-Byrd","fullName":"Julie A Williams-byrd","fullNameInverted":"Williams-Byrd, Julie A","middleInitial":"A","primaryEmail":"julie.a.williams-byrd@nasa.gov","publicEmail":true,"nacontact":false}],"website":"https://www.nasa.gov/directorates/spacetech/innovation_fund/index.html#.VQb6gUjJzyE","libraryItems":[{"caption":"Mars Electric Reusable Flyer","file":{"fileExtension":"jpg","fileId":266956,"fileName":"7256","fileSize":23078,"objectId":266713,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"22.5 KB"},"files":[{"fileExtension":"jpg","fileId":266956,"fileName":"7256","fileSize":23078,"objectId":266713,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"22.5 KB"}],"id":266713,"title":"Project Image","description":"Mars Electric Reusable Flyer","libraryItemTypeId":1095,"projectId":93850,"primary":true,"publishedDateString":"","contentType":{"lkuCodeId":1095,"code":"IMAGE","description":"Image","lkuCodeTypeId":341,"lkuCodeType":{"codeType":"LIBRARY_ITEM_TYPE","description":"Library Item Type"}}}],"transitions":[{"transitionId":53659,"projectId":93850,"partner":"Other","transitionDate":"2017-10-01","path":"Advanced From","relatedProjectId":146090,"relatedProject":{"acronym":"","projectId":146090,"title":"Mars Electric Reusable Flyer, Year 2","startTrl":2,"currentTrl":3,"endTrl":3,"benefits":"
