Award

Wright Brothers Medal - Participate - SAE International

2018-11-06
Established in 1927, this award annually recognizes the author(s) of the best paper(s) relating to the invention, development, design, construction, or operation of an aircraft and/or spacecraft presented at a meeting of the Society or any of its sections. Consideration is given to the value of the author(s) contribution to the state of the art in furthering flight technology, whether it pertains to aircraft or spacecraft systems or their parts, components, subsystems, or accessories. This award honors Orville (an early SAE member) and Wilbur Wright, the first successful builders and operators of heavier-than-air flying equipment. The award consists of a bronze medal and a framed certificate, a $300 honorarium and is presented each year at an SAE aerospace meeting.

Wright Brothers as Aeronautical Engineers

1951-01-01
510171
BY working from notebook memoranda, personal correspondence files, old photographs, and the original laboratory instruments, the author has been able to gather together the story of how the Wright brothers, starting in 1899 with an idea for controlling the flight of a glider, were able, by 1903, to develop a machine that was capable of powered flight. The author describes this airplane and its engine as well as the 1904-1905 and 1908 ones. The latter was the first airplane to pass U. S. Army acceptance tests.

An average person in North America comes in regular contact with an amazing number of real-time systems on a regular basis. For example, an automobile today can have upward of 40 plus real time systems on board. A residential house has real-time systems in many household electronics. Real-time systems today deliver many customer-facing functionalities. There is a need to express requirements in a manner relevant the customers, for purposes of validation and verification. The proliferation of real-time systems on a single device also creates opportunities for reuse of functionality that rarely existed before. Use Case technique approaches requirements from a scenario perspective. Scenario provides context and external view points that are better suited to address the validation, verification and reuse challenges. In this paper, we present: A few examples of extending use cases for real-time systems to capture system functional requirements.

Writing Good Technical Safety Requirements

2016-04-05
2016-01-0127
One of the key premises of the ISO 26262 functional safety standard is the development of an appropriate Technical Safety Concept for the item under development. This is specified in detail in Part 4 of the standard - Product development at the system level. The Technical safety requirements and the technical safety concept form the basis for deriving the hardware and software safety requirements that are then used by engineering teams for developing a safe product. Just like any other form of product development, making multiple revisions of the requirements are highly undesirable. This is primarily due to cost increases, chances of having inconsistencies within work products and its impact on the overall project schedule. Good technical safety requirements are in fact the foundation for an effective functional safety implementation.

Writing Software Specifications Using Interface Matrix

2007-04-16
2007-01-1618
Software intelligence in most products is a function of several systems working together to produce properties and behavior different than those of components. The disciplines of gathering such intelligence are often missing. That is why typical software has many missing and ambiguous requirements. The purpose of this paper is to show how to capture unknown requirements through an interactions matrix based on a system-of-systems concept.

Writing Technical Reports that Communicate

1968-02-01

The function of all technical reporting can be stated in a single word -- communication. A technical report fails in its purpose precisely in the degree that it fails to communicate. It is very important that engineers, scientists, and technicians know how to write clear, concise and understandable reports -- reports that communicate! The individual who develops this ability will benefit himself, his company, and his profession. This paper shows some of the important steps that lead to writing technical reports that communicate.
