Pallett and Shaheen Ahmad Real-Time Robot Control Laboratory, School of Electrical Engineering, Purdue University West Lafayette, IN 47907 USA ABSTRACT In this report we determine the dynamic model of a miniature helicopter in hovering flight. Identification procedures for the nonlinear terms are also described. The model is then used to design several linearized control laws and a neural network controller. The controllers were then flight tested on a miniature helicopter flight control test bed the details of which are also presented in this report. Experimental performance of the linearized and neural network controllers are discussed. -

As the blades of a Where * is the air density, 4 is the velocity, '5 is the lift coefficient and 6 is gravity as a means to fly. Lift is generated mainly by the the surface area of the wing. Even though most of these components are helicopter rotate against the air, the air pushes back on the rd wings due to their shape. An Airfoil is a cross-section of a relatively easy to measure, the lift coefficient is highly dependable on the blades following Newtons 3 Law of Motion: “To every wing, it is a streamlined shape that is capable of generating shape of the airfoil. Therefore it is usually calculated through the angle of action there is an equal and opposite reaction”. This significantly more lift than drag. Drag is the air resistance attack of a specific airfoil as portrayed in charts much like the following: reaction force is translated into the fuselage of the acting as a force opposing the motion of the aircraft. helicopter via torque, and can be measured for individual % & -/ 0 blades as follows: ! = #$ = '()*+ ∫ # 1# , where $ is the & -.

Helicopter Flying Handbook (FAA-H-8083-21B) Chapter 8
Chapter 8 Ground Procedures and Flight Preparations Introduction Once a pilot takes off, it is up to him or her to make sound, safe decisions throughout the flight. It is equally important for the pilot to use the same diligence when conducting a preflight inspection, making maintenance decisions, refueling, and conducting ground operations. This chapter discusses the responsibility of the pilot regarding ground safety in and around the helicopter and when preparing to fly. 8-1 Preflight There are two primary methods of deferring maintenance on rotorcraft operating under part 91. They are the deferral Before any flight, ensure the helicopter is airworthy by provision of 14 CFR part 91, section 91.213(d) and an FAA- inspecting it according to the rotorcraft flight manual (RFM), approved MEL. pilot’s operating handbook (POH), or other information supplied either by the operator or the manufacturer. The deferral provision of 14 CFR section 91.213(d) is Remember that it is the responsibility of the pilot in command widely used by most pilot/operators. Its popularity is due (PIC) to ensure the aircraft is in an airworthy condition. to simplicity and minimal paperwork. When inoperative equipment is found during preflight or prior to departure, the In preparation for flight, the use of a checklist is important decision should be to cancel the flight, obtain maintenance so that no item is overlooked. [Figure 8-1] Follow the prior to flight, determine if the flight can be made under the manufacturer’s suggested outline for both the inside and limitations imposed by the defective equipment, or to defer outside inspection. -
Paper Helicopters Preparation
Paper Helicopters Preparation CLASS LEVEL First – sixth class OBJECTIVES Content Strand and Strand Unit Energy & forces, Forces Through investigation the child should be enabled to come to appreciate that gravity is a force, SESE: Science Curriculum page 87. In this activity children explore how some things fall and how varying the size of the rotor blades, the shape of the rotor blades and the weight of a paper helicopter affect the way a helicopter spins. Skill development Through completing the strand units of the science curriculum the child should be enabled to design, plan and carry out simple experiments, having regard to one or two variables and the need to sequence tasks and tests, SESE: Science Curriculum page 79. This activity helps them understand fair testing by changing only one variable (i.e. shape only or length only) at a time. Investigating; experimenting; observing; analysing; measuring/timing; recording and communicating. CURRICULUM LINKS Mathematics Data / representing and interpreting data SESE: History Continuity and change over time/ technological and scientific developments over long periods BACKGROUND A previous activity on how things fall (i.e. the weight of the object is not a factor – Galileo and the Leaning Tower of Pisa) would help understanding of this activity, but not essential. MATERIALS/EQUIPMENT Paper, Ruler, Paper Clips, Scissors Templates of different sizes PREPARATION Test out a few thicknesses of paper/cardboard first to see that some of them spin. BACKGROUND The shape of the helicopter rotor blades make it spin INFORMATION when dropped from a height. Gravity pulls the helicopter down. The air resists the movement and pushes up each rotor separately, causing the helicopter to spin. -
Sikorsky S70i CAL FIRE HAWK Fact Sheet
SIKORSKY S70i CAL FIRE HAWK CALIFORNIA DEPARTMENT OF FORESTRY & FIRE PROTECTION AVIATION PROGRAM MANUFACTURER CREW Sikorsky Aircraft, Stratford, Connecticut (Built in Mielec, Poland) One pilot, two Helitack Captains, an operations supervisor, and up to AIRCRAFT FIRE BUILD-UP nine personnel. United Rotorcraft, Englewood, Colorado PAYLOAD ORIGINAL OWNER Fixed tank - 1000 gallons of water/foam with pilot controlled drop volumes. CAL FIRE, 2019 ACQUIRED BY CAL FIRE SPECIFICATIONS Gross Weight: Internal 22,000 lbs./ In 2018 CAL FIRE received approval from the Governor’s Office to purchase External 23,500 lbs. up to 12 new Sikorsky S70i firefighting helicopters from United Rotorcraft. Cruise Speed: 160 mph These new generation helicopters will replace CAL FIRE’s aging fleet of Night Vision Capable 12 Super Huey Helicopters. The new generation of S70i CAL FIRE HAWK Range: 250 miles helicopters will bring enhanced capabilities including flight safety, higher Endurance: 2.5 hours payloads, increased power margins, and night flying capabilities. Rotor Diameter: 53 feet and 8 inches Engines: Twin turbine engine, T700-GE701D MISSION The CAL FIRE HAWK’s primary mission is responding to initial attack wildfires and rescue missions. When responding to wildfires, the helicopter can quickly deliver up to a 9-person Helitack Crew for ground firefighting operations and quickly transition into water/foam dropping missions. The helicopters are also used for firing operations using either a Helitorch or a Chemical Ignition Device System (CIDS) on wildland fires or prescribed burns, transporting internal cargo loads, mapping, medical evacuations and numerous non-fire emergency missions. The CAL FIRE HAWK is also equipped with an external hoist for rescue missions. -

ACRP Problem Statement: 89 Helicopter and Tiltrotor Noise Modeling Procedures Document TAGS: Airport Planning, Environment, Noise Impacts, Operations, Policy, Public Relations OBJECTIVE The objective of this research effort is to develop written documentation on best available methods to model community noise generated from helicopter and tiltrotor operations. The document should address integrated and simulation modeling techniques, and methods for collecting and analyzing noise source data, and outline noise source development protocols. The language and format of the document shall be suitable for standards submission. BACKGROUND Existing noise modeling standards [SAE-AIR-1845; ICAO, Doc-29] for prediction of fixed wing community noise have been promulgated internationally and serve as the technical justification and defensible rationale upon which numerous noise models such as the Aviation Environmental Design Tool (AEDT) and the Integrated Noise Model (INM) rely. -
