History Lesson: Importance of the Inclinometer for Flight

Orville and Wilbur Wright may have never found success if not for the inclinometer. Their original aircraft designs were missing a critical piece of innovation that was being used by foresters and other industry pioneers. This simple device is known as an inclinometer (or slip indicator).

The 1902 Flyer had problems maintaining level flight throughout a turn due to the aircraft slipping or skidding through the air, which dramatically reduced the lift generated by the wings they had designed.

While in his sleep, Orville awoke one night after a dream in which he saw the problem:  he needed to add yaw to an aircraft's turn which at the time only included roll. The Wright 1903 Flyer was the first model designed by the Wright brothers to include a rudder, which allowed the aircraft to fly balanced (coordinated) through a turn instead of sliding sideways through a turn using only roll from the ailerons located on the wings. The use of inclinometers on flying aircraft was immediately needed for the pilot to know how much input was needed from the rudders for a coordinated turn.

Early inclinometers were as simple as a pendulum hung where the pilot could see how his aircraft was moving through the air with respect to the force of gravity. The most famous early inclinometer was found in the Spirit of St. Louis piloted by Charles Lindbergh. This Rieker inclinometer used by Charles on his solo flight across the Atlantic Ocean was a simple yet reliable design that is still used today.

As flight instrumentation advanced, the inclinometer became more commonly known as the slip indicator. Modern day inclinometers are sealed glass tubes curved upwards with a ball sitting at the bottom surrounded by fluid in the tube. The ball gives an indication of how coordinated the turn is, whether the aircraft is slipping (skidding) or flying coordinated throughout the turn. The forces of gravity against the aircraft precession forces cause movement of the ball within the tube.

Flight instructors will often tell their students to step on the ball meaning the inclinometers' ball is not centered at the bottom of the tube and the student pilot must add rudder to the aircraft turn to become balanced and coordinated.

The reason why coordinated turns are so important is due to how gravity is felt and applied to the opposing force (lift) generated by the aircraft wings. While an aircraft is slipping or skidding through turns gravity is felt to the side and it pulls the aircraft sideways towards the earth making the lift generated by the wings less effective. When an aircraft becomes coordinated, gravity is pulling directly through the center of the aircraft perfectly opposite of the lift being generated by the wings. This results in a more pleasant feeling for the passengers aboard the aircraft as well as a more efficient flight. In a perfectly coordinated turn many passengers will not feel the aircraft is turning at all due to the weight of gravity being applied directly perpendicular to the seat they are sitting in.

Inclinometers and the New Sony Alpha 7 Camera

Inclinometers are used everywhere!

Sony Alpha 7: The World's Lightest Full-Frame Camera With Interchangeable Lens

Full Article by Mark Sparrow (Mr. Sparrow is a top notch technology writer with an emphasis on digital photography)


"...When it comes to handling I really loved the A7. It sits snugly in the hand and is light enough to use one-handed if you need to. The articulating LCD screen is great for taking candid shots from waist level and there’s also a handy on-screen spirit level and inclinometer to help you keep your pictures straight. I came to depend heavily on this handy little gizmo, especially for architectural and landscape shots. The more pictures I shot with the A7, the more I grew to like it, although I’d probably not recommend it for sports photography as the continuous shooting mode isn’t quite as fast as something like the Nikon D4..."


Just goes to show you that inclinometers are not only for construction equipment or heavy industrial applications for safety purposes, but across many industries and applications! Knowing one's angle or level condition is dependent on some type of level device such as an inclinometer.

Terex announces equipment updates

Terex announces equipment updates

Jason Cannon November 12, 2013

Terex says it has updated its Hi-Ranger TM100 aerial and General 80 digger derrick. The company says its TM100 telescoping, non-overcenter, material handling aerial is now lighter with a decreased travel height to support installation on standard factory trucks, including 6 x 6 chassis. Weight savings come from new outriggers and revised sub-frame configuration that also allows for increased payload capacity, the company adds.

The TM100 stands 13 feet tall and nearly 38-and-a-half feet long with a gross vehicle weight of rating of 52,000 pounds. The company says the unit is designed to achieve 90 degrees of lower boom articulation, 100 feet working height and 51 feet side reach with a 95-foot bottom-of-platform height. It also features an end-mounted, two-person, D-shaped, 800-pound-capacity working platform.
The General 80 digger derrick update includes a 79.9-foot sheave height, a 26,600-pound lift capacity at the 10-foot, fully retracted radius, a 1,840 pound lift capacity at 0 degrees fully extended and a 36.4-foot digging reach.

Other enhancements include boom extension rollers, a digger hanger shaft, a load moment limiter and a hydraulic, interlocking tilt pole guide.

DOT Roadway Safety Plan


DOT Roadway Safety Plan


During the first decade of the 21st century, over 400,000 people died on America’s roadways, while millions suffered life-altering injuries. Such incidents have had a profound impact, not only on those injured, but also on their families and communities. The Nation must significantly reduce roadway crashes, deaths, injuries, and the terrible social and economic costs that are consequently borne by the American public.

The U.S. Department of Transportation (DOT) developed the Roadway Safety Plan based on the premise that significantly reducing roadway fatalities will require fresh ideas, stronger partnerships, and tremendous resolve. DOT will continue to build upon past successes, lessons learned, and current and future trends.

Senior DOT leaders initiated this Roadway Safety Plan to bring an integrated focus to roadway safety issues. A Roadway Safety Plan Working Group (Working Group) was assembled that includes a cross section of representatives from the Federal Highway Administration (FHWA), the Federal Motor Carrier Safety Administration (FMCSA), the National Highway Traffic Safety Administration (NHTSA), and the Research and Innovative Technology Administration (RITA), supported by the Office of the Secretary of Transportation (OST). Each member was identified for his or her subject matter expertise.

The Roadway Safety Plan leverages multiple strategic and operational plans that have been developed over the years to address roadway safety issues, both within DOT and by external stakeholder groups. The Working Group expanded these existing plans, examining new opportunities for and methods of innovation, integration, and collaboration.

Ultimately, the Roadway Safety Plan seeks to align with the safety focus of the strategic, legislative, budgetary, and performance planning processes that will be needed to advance its ideas.

Rieker Inc is currently working with State DOT administrators and engineers to provide advanced technology that significantly improves specific aspects of Roadway Safety. Based on the Federal Highway Administration (FHWA) guidelines on how to determine safe curve speed, our new system allows the operator to drive a select road or roads as needed, with traffic, while automatically recording relevant road telemetry (including curve radius, side friction, and super elevation) - creating a permanent record for later analysis via our Curve Advisory Reporting System (analytics and auto calculations) software. The goal coincides with the Zero Fatality initiative to create technology that not only makes it safer for DOT employees to do their job, but for the general driving public  - standardizing the country wide problem of inaccurate and often times incorrect safe curve advisory warning signs.

The Spirit of St. Louis and Rieker Inclinometers!

In the early 1920's, the US Government contracted Rieker Instruments Company to produce bubble style pitch and roll indicators for the fast emerging aircraft market.   

One of the most famous inclinometer fluid filled vial type installations - if not the most famous - was the use of a pair of Rieker glass tube instruments on the panel of the Ryan NYP "The Spirit of St. Louis".  In 1927 Charles Lindbergh chose the lightweight Rieker P-1057 Degree Inclinometer to give him climb and descent angle information.  

Rieker's ability to produce precise instrumentation for the aviation industry led to our status as the dominant supplier to Original Aircraft Manufacturers to this day.  Our specialty glass department still hand crafts replacement slip indicators for vintage aircraft around the world.

Applications for Inclinometers in the Shipbuilding Industry

Inclinometers are a specialized family of instruments used to measure tilt, elevation, and depression and these tools have applications in a wide array of industries from forestry to manufacturing and aerospace applications. Among these industries is shipbuilding which has been making use of inclinometers in one form or another for many years and there are two primary applications for inclinometers in shipbuilding: - 
  • Construction uses both during and after ship construction is complete - 
  • Navigation and safety concerns such as measuring the heel of the ship while it's at sea.

Shipbuilding

Inclinometers are known as "swiss army knife" of shipbuilding because they are used throughout the process and, also, to ensure that the finalized ship is seaworthy and safe. Chief among the reasons for using inclinometers in shipbuilding is the fact that they are used in equipment such as cranes and other heavy-lift equipment to ensure that the item being lifted is kept level. Careful placement of panels, components, and parts of the ship's structure is paramount to its structural integrity and to its ability to safely navigate the sea and inclinometers ensure that these components are kept level and precise

Stability Testing and Navigation


The final use for inclinometers in shipbuilding is to perform an inclining experiment, also know as an inclining test. The inclining test determines the ship's overall stability, its lightship weight–the weight of the ship when all extraneous weight has been removed–, and the ship's center of gravity and must be performed on all ships measuring 24 meters or longer. The inclinometer's role in an inclining test is to measure the degrees to which a ship heels when a series of weights are moved around the surface of the ship. The measurements resulting from the inclining test are crucial to maintaining the ship's stability are also used during navigation.

The measurements and readings from inclining experiments are most often used on sailboats, though other ships can make use of them. A sailboat must tilt, or heel, at a specific degree to ensure that it is sailing efficiently and an inclinometer helps the ship's crew ensure that it is doing so. Furthermore, the inclinometer will notify the ship's crew if the heel is too aggressive and the ship is in danger of capsizing. Finally, an inclinometer can be used as a navigational device by the ship's crew to determine the latitude or to determine deviation from a set course.

From manufacturing to testing inclinometers are used in nearly every aspect of shipbuilding. These devices not only help to ensure that surfaces are free from defects and malformations but, also, they are useful in determining center of gravity and ship weights. For more information about inclinometers, and for help determining the specific inclinometer package that's best for your inclining project, contact Rieker Inc, and they will be happy to help.
