The Four Forces of Flight
1 Aviation For Kids: A Mini Course For Students in Grades 2-5 Adopted from AvKids for use by the EAA The AvKids Program developed by the National Business Aviation Association (NBAA) represents what may be the best short course in aviation science for students in grades 2-5. The following pages represents a slightly modified version of the program, with additions and deletions to provide the best activities for the development of the four forces of flight. In addition, follow up activities included involve team work problem solving in geography, writing, and mathematics. In addition, what may be the best aviation glossary for young students has been included. Topics Covered in The Mini-Course 1. The Four Forces of Flight 2. Thrust 3. Weight 4. Drag 5. Lift 6. The Main Parts of a Plane 7. Business Aviation: An Extension of General Aviation 8. Additional Aviation Projects 9. Aviation Terms 2 The Four Forces of Flight An aircraft in straight and level, constant velocity flight is acted upon by four forces: lift, weight, thrust, and drag. The opposing forces balance each other; in the vertical direction, lift opposes weight, in the horizontal direction, thrust opposes drag. Any time one force is greater than the other force along either of these directions, an acceleration will result in the direction of the larger force. This acceleration will occur until the two forces along the direction of interest again become balanced. Drag: The air resistance that tends to slow the forward movement of an airplane due to the collisions of the aircraft with air molecules. -

Envolvendo um enorme número de empresas diferentes, sempre apresentou um desafio entre integração de software e hardware das mais diversas áreas. Os computadores necessários para controlar e processar toda essa estrutura necessitam ser ágeis, confiáveis e capazes de executar todos os desafios propostos por esta tecnologia. Controlando estes computadores, o sistema operacional Linux mostrou-se capaz de realizar esta missão, sendo atualmente utilizado nos grandes foguetes reutilizáveis ou em drones sob solo marciano. Este estudo exploratório, realizado como revisão bibliográfica, destaca a aplicação do Linux, assim como a tecnologia espacial e seus desafios. Os dados obtidos durante a pesquisa possibilitaram afirmar que a NASA e a SpaceX mudaram a forma como equipes e empresas atuam nas missões espaciais. O Linux vem permitindo que equipes de cientistas em universidades ou empresas de tecnologia de pequeno porte atuem de forma importante para o sucesso da nova era espacial. A missão espacial DM-2 ocorrida em maio de 2020, é a prova do sucesso da utilização do Linux. -
Landing Safely on Earth, Then the Moon and Mars
AIRCRAFT TECHNOLOGY, INTEGRATION AND OPERATIONS send humans beyond low-Earth orbit for the first time since Apollo 17 in 1972. NASA’s Mars 2020 mission, with the 1,050-ki- logram Perseverance rover and new technology demonstration 2-kilogram Ingenuity Mars heli- copter, were launched from Cape Canaveral Air Force Station in Florida in July. The rover is sched- uled to land on the red planet at Jezero Crater. Sev- eral new technologies will operate during entry, descent and landing, including Range Trigger and Terrain-Relative Navigation, while Perseverance descends under the 21.5-meter-nominal-diame- ter Disk Gap Band parachute. In June, the U.S. Army initiated the process to develop the Next Generation Static Line personnel parachute for multidomain operations. The Army Combat Capabilities Development Command Sol- dier Center is leading the technical development and spent the end of the year identifying the capa- bilities of commercially available parachutes in the U.S. and allied nations. These data, along with user input, will be used to conduct a detailed analysis and determine a potential path in 2021.

Space Tales Photograph courtesy of NASA A boom in space-based science is under way. Private companies ferry people and cargo to and from the International Space Station, where astronauts run increasingly automated experiments. While one UCSB team reviews data from a recent mission, another prepares for one ahead. Meanwhile, Netfl ix plans a movie about UCSB College of Engineering graduate and NASA astronaut José Hernández. The SpaceX Crew Dragon Endeavour is pictured high above Earth during its approach to the International Space Station. 13 Photograph courtesy of Allan Hancock College Net ix Movie Former astronaut José Hernández has shared his inspirational story with students to Tell the across the country, including (shown) at a community event in Santa Maria in 2017. he inspirational story of former NASA astronaut José Story of UCSB Hernández, a graduate of UC Santa Barbara’s Electri- Tcal and Computer Engineering Department who went from California’s migrant farmworker community to orbiting Alumnus the Earth, will be the subject of a Netfl ix original movie set to begin production this summer. The working title of the fi lm is “A Million Miles Away.” Hernández spent fourteen days in space in 2009 as a fl ight Astronaut’s engineer on board STS-128, a NASA Space Shuttle mission to the International Space Station (ISS). But his fl ight path to space, where he became the fi rst person to send a tweet in Path to Space Spanish from space, was not easy. “The fi lm shows my life as a migrant farmer who went from working in the fi elds with his parents to becoming an astronaut,” said Hernández, who described his nomadic child- hood of moving each year with his family to various locations throughout California and Mexico. -

Aerobies. 5. Paper Airplane Diagrams. 6. Epilogue. 1. Introduction. a) Rationale. Imagine your students actively involved in a learning activity. If you’ve been teaching for a while, you have undoubtedly developed certain lessons that you look forward to teaching. You are probably also always on the lookout for new ones. Paper airplanes seem like a good topic for such a lesson. From the beginnings of time, Curriculum Unit 88.06.02 1 of 13 man has been interested in flying through the sky. Ancient religions made the heavens the realm of their gods. The gods did not suffer our limitations of being restricted to the earth. Man looked to the birds and saw freedom. Where we plodded, the birds soared. Paper airplanes offer students the opportunity to step back from daily routines and pressures and enter the fanciful world of flight. The freedom of design inherent in paper airplanes appeals to many youngsters. They enjoy taking a piece of paper, folding it into whatever shape they desire, and flying their particular creation across the room. Another child then tries to build a plane that will fly straighter or farther or longer. Each person can participate in a critique of each other’s plane. -

Airplane Explorations
Airplane explorations Children are fascinated with airplanes. This Older children may enjoy making planes that the youngest children in fascination can be a doorway to rich STEM the program can play with. Young preschoolers may need assistance (science, technology, engineering, and math) folding their planes. Toddlers will enjoy chasing after planes thrown learning even for the youngest children. When by older people and bringing them back for another flight.
