  ITEM 8.01 - OTHER EVENTS
  
  On June 22, 2006, the  Registrant  issued the following  announcement  over the
  newswire and posted it on its website (www.sonexresearch.com):
  
  
  SONEX SIGNS LETTER OF INTENT FOR UAV HEAVY FUEL ENGINE TECHNOLOGY LICENSE
  
  
  ANNAPOLIS,  MARYLAND,  June 22, 2006 - SONEX RESEARCH, INC. (OTC SONX), a leader
  in the field of combustion technology,  announced that it has signed a Letter of
  Intent  (LOI) with a producer of unmanned  aerial  vehicles  (UAVs)  pursuant to
  which the parties have expressed an intention to complete  negotiations  for and
  conclude a  technology  licensing  agreement  by the end of the summer.  The LOI
  contemplates  an exclusive  license for a part of the patented Sonex  Combustion
  System (SCS) heavy fuel engine  (HFE)  technology  applicable  to a certain size
  range of small engines.  While Sonex must caution that the definitive  licensing
  agreement has not yet been finalized,  it has received a non-refundable  deposit
  of  $25,000  towards  future  royalties  as part of the  LOI.  The LOI  contains
  confidentiality  provisions  that preclude the disclosure of the customer's name
  and further details of the  relationship at this time. Both parties will release
  a joint  statement upon  completion of the agreement  including the terms of the
  joint activities.
  
  The  Department  of Defense  (DoD) now  requires  engines used in UAVs and other
  military  applications for which gasoline  storage and use are  undesirable,  to
  operate on less  volatile,  heavy  fuels to reduce the  hazard  associated  with
  gasoline. Sonex has established a viable HFE technology baseline by applying its
  patented SCS modified combustion chamber design and proprietary  starting system
  to the  conversion  of  lightweight,  spark-ignited  (SI),  two-stroke  gasoline
  engines for use in military  applications such as UAVs to start and operate with
  reduced fuel consumption and low smoke on kerosene-based  heavy fuels JP-5, JP-8
  and D-2 diesel (with lubricant  additive) while retaining the ignition precision
  of the SI process.  The SCS process for two-stroke engines achieves  in-cylinder
  control of ignition and combustion through the chemical/turbulent enhancement of
  combustion  via  combustion  chamber  modifications  that  change  the  chemical
  characteristics  and fuel  disbursement  characteristics  within the  combustion
  chamber.
  
  Sonex has previously  announced two agreements with this unnamed  customer,  the
  first in  October  2005 worth  approximately  $113,000  to develop a  combustion
  system to convert the small,  two-stroke,  SI gasoline engine used in one of the
  customer's  production  UAVs to heavy fuel  operation.  Following the successful
  demonstration  to  the  customer  in  February  2006  of a  "Proof  of  Concept"
  laboratory  SCS HFETM  prototype  operating  on JP-5  heavy  fuel,  the  Company
  announced  the  award  in  March  2006  of a  follow-on  Phase 2  project  worth
  approximately $235,000 to develop, fabricate and qualify pre-production,  flight
  ready SCS HFEsTM.  Phase 2 is expected to be completed  this  summer,  following
  which the  parties  plan to  undertake  additional  phases for SCS HFETM  flight
  certification testing and production introduction.

  About Sonex
  
  Sonex  Research,  Inc.,  a leader  in the  field of  combustion  technology,  is
  developing its patented Sonex Combustion  System (SCS)  piston-based  technology
  for in-cylinder  control of ignition and  combustion,  designed to increase fuel
  mileage and reduce  emissions  of internal  combustion  engines.  Sonex plans to
  complete  development,  commercialize  and  market  its  Sonex  Controlled  Auto
  Ignition (SCAI)  combustion  process to the automotive  industry to improve fuel
  efficiency of gasoline powered vehicles.  Additionally,  independent third-party
  testing has confirmed the potential of the SCS application  for  direct-injected
  diesel  engines  to  significantly   reduce  harmful  soot  in-cylinder  without
  increasing  fuel  consumption.  Other  SCS  designs  are being  used to  convert
  gasoline engines of various sizes to operate on safer, diesel-type "heavy fuels"
  for use in military and commercial  applications requiring light weight and safe
  handling and storage of fuel, such as in UAVs (unmanned aerial vehicles).
  
  
  CAUTION REGARDING FORWARD-LOOKING STATEMENTS
  
  "Forward-looking"  statements  contained in this report, as well as all publicly
  disseminated  material about the Company, are made pursuant to the "safe harbor"
  provisions of the Private  Securities  Litigation Act. Such statements are based
  on current  expectations,  estimates,  projections and assumptions by management
  with respect to matters such as commercial acceptance of the SCS technology, the
  impact of  competition,  and the  Company's  financial  condition  or results of
  operations.  Readers are cautioned  that such  statements  are not guarantees of
  future  performance and involve risks and uncertainties  that could cause actual
  results to differ  materially from those  expressed in any such  forward-looking
  statements.
  
  
  RISK FACTORS
  
  Additional  information  regarding  the risks  faced by Sonex is provided in the
  Company's  periodic  filings with the Securities and Exchange  Commission  (SEC)
  under the heading "Risk  Factors".  Such filings are available upon request from
  the Company or online in the SEC's EDGAR database at  www.sec.gov.  The Company,
  however,  is delinquent in its filings with the SEC. It has not filed its Annual
  Reports on Form 10-KSB for the years ended December 31, 2004 and 2005 because it
  lacks the financial  resources to engage its independent  accountants to conduct
  audits of the December 31, 2004 and 2005  financial  statements,  and because it
  lacks the  staffing to prepare  the Form 10-KSB  itself due in large part to the
  amount of time  management has spent in responding to  litigation.  For the same
  reasons,  the  Company  has been  unable to file its  Quarterly  Reports on Form
  10-QSB for 2005 and 2006.  The Company is unable to predict when it will be able
  to make these  filings and there can be no  assurance  that the filings  will be
  made at all. In addition, there can be no assurance that a public market for the
  Company's Common Stock will continue to exist.
