  • How Doc Draper Became the Father of Inertial Guidance
    (Preprint) AAS 18-121 HOW DOC DRAPER BECAME THE FATHER OF INERTIAL GUIDANCE Philip D. Hattis* With Missouri roots, a Stanford Psychology degree, and a variety of MIT de- grees, Charles Stark “Doc” Draper formulated the basis for reliable and accurate gyro-based sensing technology that enabled the first and many subsequent iner- tial navigation systems. Working with colleagues and students, he created an Instrumentation Laboratory that developed bombsights that changed the balance of World War II in the Pacific. His engineering teams then went on to develop ever smaller and more accurate inertial navigation for aircraft, submarines, stra- tegic missiles, and spaceflight. The resulting inertial navigation systems enable national security, took humans to the Moon, and continue to find new applica- tions. This paper discusses the history of Draper’s path to becoming known as the “Father of Inertial Guidance.” FROM DRAPER’S MISSOURI ROOTS TO MIT ENGINEERING Charles Stark Draper was born in 1901 in Windsor Missouri. His father was a dentist and his mother (nee Stark) was a school teacher. The Stark family developed the Stark apple that was popular in the Midwest and raised the family to prominence1 including a cousin, Lloyd Stark, who became governor of Missouri in 1937. Draper was known to his family and friends as Stark (Figure 1), and later in life was known by colleagues as Doc. During his teenage years, Draper enjoyed tinkering with automobiles. He also worked as an electric linesman (Figure 2), and at age 15 began a liberal arts education at the University of Mis- souri in Rolla.

  • Performance Improvement Methods for Terrain Database Integrity

Russ College of Engineering and Technology of Ohio University In partial fulfillment of the requirements for the degree Master of Science Ananth Kalyan Vadlamani March 2004 This thesis entitled PERFORMANCE IMPROVEMENT METHODS FOR TERRAIN DATABASE INTEGRITY MONITORS AND TERRAIN REFERENCED NAVIGATION BY ANANTH KALYAN VADLAMANI has been approved for the School of Electrical Engineering and Computer Science and the Russ College of Engineering and Technology by Maarten Uijt de Haag Assistant Professor of Electrical Engineering and Computer Science R. Dennis Irwin Dean, Russ College of Engineering and Technology VADLAMANI, ANANTH K. M.S. March 2004. Electrical Engineering and Computer Science Performance Improvement Methods for Terrain Database Integrity Monitors and Terrain Referenced Navigation (115pp.) Director of Thesis: Maarten Uijt de Haag Terrain database integrity monitors and terrain-referenced navigation systems are based on performing a comparison between stored terrain elevations with data from airborne sensors like radar altimeters, inertial measurement units, GPS receivers etc. This thesis introduces the concept of a spatial terrain database integrity monitor and discusses methods to improve its performance. Furthermore, this thesis discusses an improvement of the terrain-referenced aircraft position estimation for aircraft navigation using only the information from downward-looking sensors and terrain databases, and not the information from the inertial measurement unit. Vertical and horizontal failures of the terrain database are characterized. Time and frequency domain techniques such as the Kalman filter, the autocorrelation function and spectral estimation are designed to evaluate the performance of the proposed integrity monitor and position estimator performance using flight test data from Eagle/Vail, CO, Juneau, AK, Asheville, NC and Albany, OH.

Each has its own operational challenges. And for some, these challenges have grown — as busier airspace and ever-more- demanding flight environments have increased the focus on safety, industry wide. An FAA task force identified three primary areas where operational risks for helicopters need special attention: 1) inadvertent flight into instrument meteorological (IMC) conditions, 2) night operations, and 3) controlled flight into terrain (CFIT). Many ongoing studies have reinforced these findings. And in response, many operators are now asking for technologies that can proactively (and affordably) help address these safety issues. To that end, Garmin is focusing our decades of experience in aviation safety technology on the specialized needs of today’s helicopter community.

    Advisory u.s. Department ofTransportation Federal Aviation Circular Ad.nnlstratlon Subject: CRITERIA FOR OPERATIONAL Date: 3/18/97 AC No: 120-67 APPROVAL OF AUTO FLIGHT Initiated By: AFS-400 Change: GUIDANCE SYSTEMS 1. PURPOSE. This advisory circular (AC) states an acceptable means, but not the only means, for obtaining operational approval of the initial engagement or use of an Auto Flight Guidance System (AFGS) under Title 14 of the Code of Federal Regulations (14 CFR) part 121, section 121.579(d); part 125, section 125.329(e); and part 135, section 135.93(e) for the takeoff and initial climb phase of flight. 2. APPLICABILITY. The criteria contained in this AC are applicable to operators using commercial turbojet and turboprop aircraft holding Federal Aviation Administration (FAA) operating authority issued under SPAR 38-2 and 14 CFR parts 119, 121, 125, and 135. The FAA may approve the AFGS operation for the operators under these parts, where necessary, by amending the applicant's operations specifications (OPSPECS). 3. BACKGROUND. The purpose of this AC is to take advantage of technological improvements in the operational capabilities of autopilot systems, particularly at lower altitudes. This AC complements a rule change that would allow the use of an autopilot, certificated and operationally approved by the FAA, at altitudes less than 500 feet above ground level in the vertical plane and in accordance with sections 121.189 and 135.367, in the lateral plane. 4. DEFINITIONS. a. Airplane Flight Manual (AFM). A document (under 14 CFR part 25, section 25.1581) which is used to obtain an FAA type certificate.

    AVIATION OCCURRENCE REPORT GEAR-UP LANDING COUGAR HELICOPTERS INC. EUROCOPTER AS332L SUPER PUMA (HELICOPTER) C-GQCH ST. JOHN=S, NEWFOUNDLAND 01 JULY 1997 REPORT NUMBER A97A0136 The Transportation Safety Board of Canada (TSB) investigated this occurrence for the purpose of advancing transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability. Aviation Occurrence Report Gear-Up Landing Cougar Helicopters Inc. Eurocopter AS332L Super Puma (Helicopter) C-GQCH St. John=s, Newfoundland 01 July 1997 Report Number A97A0136 Summary The crew of the Super Puma helicopter, serial number 2139, were conducting an instrument landing system (ILS) approach to runway 29 in St. John=s, Newfoundland. As the helicopter was about to touch down, the crew realized that the helicopter was lower than normal and that the landing gear was still retracted. The crew began to bring the helicopter into a hover; however, as collective pitch was applied, the nose of the helicopter contacted the runway surface. Once the hover was established, the landing gear was lowered and the helicopter landed without further incident. Damage was confined to two communications antennae, and the supporting fuselage structure of the aircraft. There were no injuries to the 2 crew members or 11 passengers. 2 Other Factual Information The flight crew were certified and qualified for the flight in accordance to exsisting regulations. The occurrence flight was the second flight of the day for the flight crew. For the first flight of the day, the first crew member arrived at 0700 Newfoundland daylight time (NDT) for the planned morning flight.
