Recert Complete

After a long absence, last flight 2006, I was able to renew my Tripoli membership, get my original number, and recertify back to level 2. Level 1 was accomplished in Nov with my scratch built Pershing 1A with 3d printed fins and nosecone on an Aerotech I218R. Level 2 was done Dec 3 with my […]

Pin valve Mods PT III

After drilling out the old pin valve I have cut some stainless 1/16 solid rod for soldering into the pin body. This will allow a higher flow rate by increasing the size of the orifice. After cutting down all that is left is some hand filing to get length close to the original, a new […]

pin valve modification part ii

In addition to reprofiliing the threads and enlarging the discharge port, other internal modifications need to be accomplished. The retaining plug for the pin needs to be drilled out to increase flow and the pin itself must be modified for a thinner stainless steel shaft. I drilled the retaining plug out to 0.190 which still […]

Pin Valve modifications

Unfortunately I have not been able to contact or obtain a pin valve from the original supplier listed in the data pack. The female threads for the forward closures for the pin valve assembly are 13/16 x 14, but interestingly enough the threads for a typical paint ball pin valve are 1/2 x 14 but […]

And so it begins

Perhaps the most important pieces of the puzzle are the data pack and the forward closures. Currently, I only have one set of closures but a second set is planned for backups in case of any problems. Next to the forward closure, the injector plate and pin valves are the next critical components. The injector […]

Investigating Potential Uses of Swarm Logic in Civilian and Military Unmanned Systems

Abstract This research is focused on the use of swarm logic (SL) in civilian and military unmanned and autonomous systems. A brief history with the discussion of current advances and technologies is presented. This paper focuses on civilian systems, communication aspects, and required infrastructure; military uses are also explored. The advantages for civilian systems are […]

Investigating the Correlation Between Airline Revenue Passenger Miles and the Issuance of Airframe and Powerplant Certificates

Abstract This paper investigates the correlation between the issuance of airframe and powerplant mechanic certificates and revenue passenger miles (RPM) flown by domestic U.S. airlines. It is theorized that the airlines are the main factor driving the employment is this field. Although there is a lead/lag effect, an increase in RPM can be an indicator […]

Unmanned Aircraft Systems Ground Control Stations Human Factors

Abstract Unmanned aircraft are unique in that the pilot does not occupy any space within the airframe so a separate cockpit also known as a ground control station must be utilized. This research traces the development of ground control stations utilized in the operation of these systems. The development of the consoles is researched including […]

Investigation of Haptic Feedback to Improve Spatial and Aircraft State Awareness of Unmanned Aircraft System Pilots

Abstract The design of unmanned aircraft system (UAS) control stations was initially based on an aircraft cockpit. It was to make them familiar to the pilots of manned aircraft who were originally chosen to operate them. However, since a UAS pilot is not aboard the aircraft, all the information related to the system must be […]

UAS Mishaps and Accidents: Training Requirements

Operating an unmanned aircraft system (UAS) comes with certain responsibilities that are intended to protect life and property. Once seen as curiosities, their capabilities have expanded to the point of autonomous operation. Even the consumer grade UAS have semi-autonomous capabilities, that when misused can cause a collision with a manned aircraft (Goglia, 2017). Because of […]
