Lawrence Hargrave was born as Laurence Hubert Hargrave on June 17, 1850. He is commonly known by his first name, Larry, or L.H. Hargrave.
Birth and Death Dates
Born: June 17, 1850
Died: October 21, 1915
Nationality and Profession(s)
Hargrave was an Australian aviator, engineer, inventor, and explorer. He is best known for his pioneering work in the development of tailless aircraft, a design that would later influence the creation of modern gliders.
Early Life and Background
Laurence Hargrave was born in Kensington, London, England. His family moved to Australia when he was three years old, settling in Kogarah, New South Wales. Hargrave developed an interest in science and mathematics at a young age, which would later serve as the foundation for his innovative work.
Major Accomplishments
Hargrave's contributions to aviation are multifaceted:
Tailless Aircraft Design: In 1907, he designed and built a tailless aircraft, the Hargrave Delta Triplane. Although it was not successful in flight tests, his design laid the groundwork for future experimentation.
Aerodynamic Research: His work on aerodynamics led to the development of more efficient wing designs, which improved the overall performance of aircraft.
Explorer and Adventurer: Hargrave participated in several expeditions, including a notable journey to Papua New Guinea (then known as British New Guinea), where he collected valuable data on tropical diseases.Notable Works or Actions
Hargrave's publications and inventions include:
Aerodynamic Experiments: In 1905, he conducted a series of experiments using kites to test aerodynamic principles.
Wing Design Innovations: His work led to the development of more efficient wing designs, which improved aircraft performance.Impact and Legacy
Hargrave's contributions to aviation have had a lasting impact on the industry:
Advancements in Aircraft Design: His tailless design paved the way for future experimentation with innovative wing configurations.
Inspiration to Others: Hargrave's work inspired other pioneers, including Sir Charles Kingsford Smith and Ross and Keith Smith.Why They Are Widely Quoted or Remembered
Lawrence Hargrave is remembered as a pioneering figure in aviation due to his:
Visionary Approach: His willingness to challenge conventional designs led to significant advancements in aerodynamics.
* Perseverance and Innovation: Despite initial setbacks, Hargrave continued to push the boundaries of what was thought possible.
His quotes and legacy serve as a testament to the power of innovation and perseverance in shaping the future of human flight.
Quotes by Lawrence Hargrave
It becomes a giant’s task to compute the result when the effect of cross seas, wind at all angles and ever varying force, arched surfaces, head resistance, ratio of weight to area, and the intelligence of the guiding power crop up.
Workers must root out the idea that by keeping the results of their labors to themselves a fortune will be assured to them. Patent fees are so much wasted money. The flying machine of the future will not be born fully fledged and capable of a flight for 1,000 miles or so. Like everything else it must be evolved gradually. The first difficulty is to get a thing that will fly at all. When this is made, a full description should be published as an aid to others. Excellence of design and workmanship will always defy competition.
![The people of Sydney who can speak of my work [on flying-machine models] without a smile are very scarce; it is doubtless the same with American workers. I know that success is dead sure to come, and therefore do not waste time and words in trying to convince unbelievers.](https://lakl0ama8n6qbptj.public.blob.vercel-storage.com/quotes/quote-1665208.png)
The people of Sydney who can speak of my work [on flying-machine models] without a smile are very scarce; it is doubtless the same with American workers. I know that success is dead sure to come, and therefore do not waste time and words in trying to convince unbelievers.
My objective is and has been for years to make the lightest and most compact flying machine that would carry me at 25 or 30 miles per hour for 10 minutes or a quarter of an hour. Current events show this is not at all an ambitious project. Want of an elementary knowledge of oil machines baulks me and causes much misdirected effort. I doubt my ability to acquire that knowledge, and feel like a fireman trying to hew out a donkey pump...
The rapid progress of aeronautics is hampered and delayed by the want of a method of ensuring automatic longitudinal and transversal stability.
To remove this obstacle I repeat or refer to such knowledge as has come under my notice, my own previously expressed views, and also describe and exhibit my last experiments and explain their novelty and utility.
As to the effect of the wave on the air, we will suppose the water to be quite flat and the air motionless, a heavy undulation comes on the scene, it has to pass, so it pushes the air up with its face, letting it fall again as its back glides onwards.
And from a poise at this station the plane may swoop down, at great disadvantage if close to the back of the wave, at various slopes and directions till it cuts into the air that is being raised by the face of the following wave, which again enables it to resume its velocity.
